85 Fun Critical Thinking Questions for Kids & Teens

Have you ever thought about using fun questions to practice critical thinking?

Students may need a little guidance to think their way through questions that lack straightforward answers.

But it is that process that is important!

How the Right Questions Encourage Critical Thinking

Every parent knows how natural it is for children to ask questions. 

It should be encouraged. After all, asking questions helps with critical thinking.

As they grow older, however, training them to answer questions can be equally beneficial.

Posing questions that encourage kids to analyze, compare, and evaluate information can help them develop their ability to think critically about tough topics in the future. 

Of course, critical thinking questions for kids need to be age-appropriate—even better if you can mix a little fun into it!

That’s what I hope to help you with today. I’ve organized the questions below into three different ages groups:

• Upper elementary
• Middle school
• High school

Introduce critical thinking gently & easily with thought-provoking exercises.

Upper Elementary

Students in upper elementary grades can be reluctant to put themselves out there, especially with answers that seem weird. 

In some cases, such hesitancy is actually fear of differing from their peers (and a barrier to critical thinking ). 

But that’s exactly why it’s important to practice answering ambiguous questions. 

We want our children to stand firm for their beliefs—not cave to peer pressure. 

Additionally, students may feel uneasy about answering serious questions, uncertain of tackling “big” problems. 

However, with careful use of creative questions for kids, it’s possible to engage even the most reluctant children in this age group. 

The idea is to simply get them interested in the conversation and questions asked.

If you have an especially reserved student, try starting with the funny critical thinking questions. 

Humor is a natural icebreaker that can make critical thinking questions more lighthearted and enjoyable. 

Of course, most younger kids just like to be silly, so playing upon that can keep them active and engaged.

With that said, here are some great questions to get you started:

1. Someone gives you a penguin. You can’t sell it or give it away. What do you do with it?

2. What would it be like if people could fly?

3. If animals could talk, what question would you ask? 

4. If you were ice cream, what kind would you be and why?

5. Do you want to travel back in time? If yes, how far back would you go? If no, why not?

6. What could you invent that would help your family? 

7. If you could stay up all night, what would you do?

8. What does the man on the moon do during the day?

9. What makes something weird or normal? 

10. Can you describe the tastes “salty” and “sweet” without using those words?

11. What does it feel like to ride a rollercoaster?

12. What makes a joke funny?

13. What two items would you take if you knew you would be stranded on an island and why?

14. Do you have a favorite way of laughing?

15. What noise makes you cringe and cover your ears? Why?

16. If you could be the parent for the day, what would you do?

17. If you could jump into your favorite movie and change the outcome, which one would you pick and why?

18. If you could be invisible for a day, what would you do?

19. What makes a day “perfect”?

20. If you owned a store, what kind of products would you sell?

21. If your parents were your age, would you be friends with them?

22. Would you still like your favorite food if it tasted the same as always, but now had an awful smell?

23. What would you do if you forgot to put your shoes on before leaving home?

24. Who would you be if you were a cartoon character?

25. How many hot dogs do you think you could eat in one sitting?

26. If you could breathe under water, what would you explore?

27. At what age do you think you stop being a kid?

28. If you had springs in your legs, what would you be able to do?

29. Can you describe the color blue to someone if they’re blind?

Middle School

At this point, students start to acquire more complex skills and are able to form their own conclusions based on the information they’re given. 

However, we can’t expect deep philosophical debates with 12 and 13 year olds. 

That said, as parent-teachers, we can certainly begin using more challenging questions to help them examine and rationalize their thought processes. 

Browse the fun critical thinking questions below for students in this age range. 

You might be surprised to see how receptive middle school kids can be to such thought-provoking (yet still fun) questions .

30. What would happen if it really did rain cats and dogs?

High School

Critical thinking takes on an entirely different role once students reach high school. 

At this age, they have a greater sense of right and wrong (and what makes things so) as well as a better understanding of the world’s challenges.

Guiding teens to delve deeper and contemplate such things is an important part of developing their reasoning and critical thinking skills. 

Whether it’s fun questions about hypothetical superpowers or tough critical thinking questions about life, older teens typically have what it takes to think their way to a logical conclusion .

The ability to think critically will often determine your success in life.

Let’s face it. Every day, we are bombarded by news, social media updates, and an avalanche of information. If you take all of this at face value, it’s easy to be deceived, misled or ripped off.

That’s why it’s important to  develop a mindset that focuses on critical thinking . This is a skill that needs to be developed in the classroom. But it’s also a valuable life skill.

With that in mind, the following post will share 85 critical thinking questions you can use to increase your awareness about different problems by carefully examining available information. 

Let’s get started…

Table of Contents

What Are Critical Thinking Questions?

Critical thinking questions are inquiries that help you think rationally and clearly by understanding the link between different facts or ideas. These questions create a seemingly endless learning process that lets you critique, evaluate, and develop a depth of knowledge about a given subject. Moreover, you get to reinforce your viewpoints or see things in a new way.

We make decisions every day, whether at work or home. Adopting logical, rational, and practical approaches in addressing various issues requiring critical thinking is essential in decision-making. Therefore, before arriving at a decision, always ask yourself relevant questions and carefully analyze the matter’s pros and cons.

Critical Thinking Questions When in an Argument

When you make an argument using a critical thinking approach, you focus on justified claims that are valid and based on evidence. It helps one establish a strong argument.

• Do I disagree with the other person? Might the person I'm arguing with be misinformed on what they are saying?
• Would I be comfortable saying what I am telling him/her if I was in front of a group of people? 
• What would happen if I lose this argument? Is engaging in this argument worth my time and energy? How will I feel if I lose?
• Is there room for ambiguity or misinterpretation? Are we arguing because I didn't make my point explicit? Should I take my time to understand his school of thought?
• Do I need some rest before saying something? Am I arguing because of other reasons other than the issues at hand? Do I need to take some time and cool down?

• Is it more important that I’m right? Am I trying to ask to prove an unnecessary point?
• Is this argument inductive, deductive, or abductive? Is it a weak or strong argument that I need to engage in? Is it compelling or sound? 
• Is my opponent sincere? Given that they are wrong, are they willing to admit that they are wrong? Can they depend on available evidence, wherever it leads?
• Are my opponents only trying to shift their burden to me? What is the best way to prove them wrong without making them feel bad?
• Are the people I'm arguing with only interested in winning, or are they trying to pass some information across and help me discover the truth?

Critical Thinking Questions When Reading a Book 

When you read a book, you probably ask yourself many “why” questions. Why is this a problem? Why did the character say that? Why is this important? The most challenging part of reading a book is assessing the information you are reading. These questions can help.

• If I learn only two things from this book, what will they be? How will they help me? How will I apply them in my daily life?
• What message are the authors trying to pass across? Are they making suggestions or providing evidence for their arguments?
• Given that almost every book is about solving problems, what is the most prevalent issue that the author is trying to solve?
• What is the author’s writing style? What strategy or master plan does the author employ to convey his/her main ideas throughout the book?
• Do I have background information about the book’s topic? If so, how is what the author is saying different from what I already know?
• What didn’t I understand from the book? Should I re-read the book to understand everything the writer is trying to convey?
• Which sections of the book do I love the most, and why? Generally, do I like this book? Should I look for more books that are written by the same author?
• If I had a chance to meet this book’s author, what questions would I ask him/her? What would I tell the writer about the book? Is it a great book worth recommending to your friends and family members?
• Who are the main characters of the book? If there is only one main character, what overarching goal does the character accomplish?
• In what ways did the protagonist change from the start of the book to the end? What caused the changes? Was the protagonist reckless in some ways? Which ways?

Critical Thinking Questions to Spot a Scam

Asking questions when you feel that a fraud or a scam is being presented to you is a good way to stretch your critical thinking muscles. Are you being emailed or messaged by a stranger? Or maybe there are other red flags you are unsure about. If so, ask these questions.

• Does it seem to be too good to be true? Is this stranger pushy or trying to lure me into making a poor decision?
• When trying out online dating: Is my new “friend” professing strong feelings towards me although we’ve only interacted for a few hours?
• Why is a stranger calling me to ask about my Social Security Number (SSN), personal contact information, or bank details while claiming they are from the bank or a phone company? 
• When buying products online, why does the seller ask me to pay for goods using an insecure payment option like Bitcoin or money order?
• Does the email I have received have any spelling or grammatical errors? Is the language used overly formal or informal?
• If I do a quick search about the exact words of the email I received, does Google indicate it's a fraud or scam?
• Why should a stranger manipulate me using obvious questions like “Would you want to be rich or poor?” While they already know the answer?
• Is the email asking me to download an attachment? Or click a link to some insecure website? 
• Is the person trying to make me feel selfish or guilty for not sending them money, whether for a donation or buying a product? 
• Is the stranger portraying a sense of urgency and using pressure tactics? Are they telling me that their family member needs urgent medical attention?

• Do I have any values that guide me in life? If so, what are these values? Am I always true to these values?
• Am I always worried about what people around me think? Can I act independently without the need to meet social expectations?

• If I wasn't afraid of anyone or anything, what would I have done? What if I didn't have any fear in me?
• If today was my last day, what extraordinary thing would I do? Can I do it right now?
• What should I do with the things that matter the most to me? 
• What things will make the greatest difference in my future life if I take action now?

• What information does my team, or I need before this discussion? 

Critical Thinking Questions About Lying

Critical Thinking Questions When Presented With a Claim

What Are the Basic Principles of Critical Thinking?

Your critical thinking skills involve gathering complete information, understanding and defining terms, questioning the methods by which we get facts, questioning the conclusions, and looking for hidden assumptions and biases.

Additionally, we can’t expect to find all of the answers, and we need to take the time to examine the big picture of it all.

Here are the basic principles:

• Disposition: Someone with critical thinking skills is often skeptical, open-minded, and practices fair-mindedness. They can look at different viewpoints and change positions if the evidence and reason lead them to do so.
• Criteria: In order to think critically, one must also apply criteria. Certain conditions must be met before someone believes in something. The information needs to be from credible sources.
• Argument: An argument is simply a statement or proposition that is shown with supporting evidence. When you use your critical thinking skills, you identify, evaluate, and construct your argument.
• Reasoning: With critical thinking comes reasoning. You must examine logical relationships among the statements being made.
• Point of View: Critical thinkers can see things from different perspectives and different points of view.

What Are Good Analysis Questions?

Analysis is a part of critical thinking that allows you to examine something carefully. Someone with analytical skills can examine the information presented, understand what that information means, and then properly explain that information to others. Analysis in critical thinking provides more clarity on the information you process.

When analyzing, you may ask yourself, “how do I know this,” how would I solve this problem,” and “why does it matter?”

Why Is Critical Thinking an Important Skill?

Critical thinking skills allow you to express thoughts, ideas, and beliefs in a better way. It also leads to improved communication while allowing others to understand you better. Critical thinking fosters creativity and encourages out-of-the-box thinking. This is a skill that can be applied to many different areas of your life.

For example, knowing the answers to critical thinking questions for a job interview will better prepare you for the interview. Many employers, during questioning, are likely to ask you critical thinking questions to assess if you have the ability to evaluate information effectively so you can make more informed decisions.

Final Thoughts on Critical Thinking Questions

Although it's common to get torn between making two or more choices, nobody wants to make the wrong decision. The only thing you can do to avoid this is use critical thinking questions to examine your situation. The answers to these questions will help you make informed decisions and help you comprehend crucial matters in your life.

5 Critical Thinking Skills Every Kid Needs To Learn (And How To Teach Them)

Teach them to thoughtfully question the world around them.

Little kids love to ask questions. “Why is the sky blue?” “Where does the sun go at night?” Their innate curiosity helps them learn more about the world, and it’s key to their development. As they grow older, it’s important to encourage them to keep asking questions and to teach them the right kinds of questions to ask. We call these “critical thinking skills,” and they help kids become thoughtful adults who are able to make informed decisions as they grow older.

What is critical thinking?

Critical thinking allows us to examine a subject and develop an informed opinion about it. First, we need to be able to simply understand the information, then we build on that by analyzing, comparing, evaluating, reflecting, and more. Critical thinking is about asking questions, then looking closely at the answers to form conclusions that are backed by provable facts, not just “gut feelings” and opinion.

Critical thinkers tend to question everything, and that can drive teachers and parents a little crazy. The temptation to reply, “Because I said so!” is strong, but when you can, try to provide the reasons behind your answers. We want to raise children who take an active role in the world around them and who nurture curiosity throughout their entire lives.

Key Critical Thinking Skills

So, what are critical thinking skills? There’s no official list, but many people use Bloom’s Taxonomy to help lay out the skills kids should develop as they grow up.

Source: Vanderbilt University

Bloom’s Taxonomy is laid out as a pyramid, with foundational skills at the bottom providing a base for more advanced skills higher up. The lowest phase, “Remember,” doesn’t require much critical thinking. These are the skills kids use when they memorize math facts or world capitals or practice their spelling words. Critical thinking doesn’t begin to creep in until the next steps.

Understanding requires more than memorization. It’s the difference between a child reciting by rote “one times four is four, two times four is eight, three times four is twelve,” versus recognizing that multiplication is the same as adding a number to itself a certain number of times. Schools focus more these days on understanding concepts than they used to; pure memorization has its place, but when a student understands the concept behind something, they can then move on to the next phase.

Application opens up whole worlds to students. Once you realize you can use a concept you’ve already mastered and apply it to other examples, you’ve expanded your learning exponentially. It’s easy to see this in math or science, but it works in all subjects. Kids may memorize sight words to speed up their reading mastery, but it’s learning to apply phonics and other reading skills that allows them to tackle any new word that comes their way.

Analysis is the real leap into advanced critical thinking for most kids. When we analyze something, we don’t take it at face value. Analysis requires us to find facts that stand up to inquiry, even if we don’t like what those facts might mean. We put aside personal feelings or beliefs and explore, examine, research, compare and contrast, draw correlations, organize, experiment, and so much more. We learn to identify primary sources for information, and check into the validity of those sources. Analysis is a skill successful adults must use every day, so it’s something we must help kids learn as early as possible.

Almost at the top of Bloom’s pyramid, evaluation skills let us synthesize all the information we’ve learned, understood, applied, and analyzed, and to use it to support our opinions and decisions. Now we can reflect on the data we’ve gathered and use it to make choices, cast votes, or offer informed opinions. We can evaluate the statements of others too, using these same skills. True evaluation requires us to put aside our own biases and accept that there may be other valid points of view, even if we don’t necessarily agree with them.

In the final phase, we use every one of those previous skills to create something new. This could be a proposal, an essay, a theory, a plan—anything a person assembles that’s unique.

Note: Bloom’s original taxonomy included “synthesis” as opposed to “create,” and it was located between “apply” and “evaluate.” When you synthesize, you put various parts of different ideas together to form a new whole. In 2001, a group of cognitive psychologists removed that term from the taxonomy , replacing it with “create,” but it’s part of the same concept.

How To Teach Critical Thinking

Using critical thinking in your own life is vital, but passing it along to the next generation is just as important. Be sure to focus on analyzing and evaluating, two multifaceted sets of skills that take lots and lots of practice. Start with these 10 Tips for Teaching Kids To Be Awesome Critical Thinkers . Then try these critical thinking activities and games. Finally, try to incorporate some of these 100+ Critical Thinking Questions for Students into your lessons. They’ll help your students develop the skills they need to navigate a world full of conflicting facts and provocative opinions.

One of These Things Is Not Like the Other

This classic Sesame Street activity is terrific for introducing the ideas of classifying, sorting, and finding relationships. All you need are several different objects (or pictures of objects). Lay them out in front of students, and ask them to decide which one doesn’t belong to the group. Let them be creative: The answer they come up with might not be the one you envisioned, and that’s OK!

The Answer Is …

Post an “answer” and ask kids to come up with the question. For instance, if you’re reading the book Charlotte’s Web , the answer might be “Templeton.” Students could say, “Who helped save Wilbur even though he didn’t really like him?” or “What’s the name of the rat that lived in the barn?” Backwards thinking encourages creativity and requires a good understanding of the subject matter.

Forced Analogies

Practice making connections and seeing relationships with this fun game. Kids write four random words in the corners of a Frayer Model and one more in the middle. The challenge? To link the center word to one of the others by making an analogy. The more far out the analogies, the better!

Primary Sources

Tired of hearing “I found it on Wikipedia!” when you ask kids where they got their answer? It’s time to take a closer look at primary sources. Show students how to follow a fact back to its original source, whether online or in print. We’ve got 10 terrific American history–based primary source activities to try here.

Science Experiments

Hands-on science experiments and STEM challenges are a surefire way to engage students, and they involve all sorts of critical thinking skills. We’ve got hundreds of experiment ideas for all ages on our STEM pages , starting with 50 Stem Activities To Help Kids Think Outside the Box .

Not the Answer

Multiple-choice questions can be a great way to work on critical thinking. Turn the questions into discussions, asking kids to eliminate wrong answers one by one. This gives them practice analyzing and evaluating, allowing them to make considered choices.

Correlation Tic-Tac-Toe

Here’s a fun way to work on correlation, which is a part of analysis. Show kids a 3 x 3 grid with nine pictures, and ask them to find a way to link three in a row together to get tic-tac-toe. For instance, in the pictures above, you might link together the cracked ground, the landslide, and the tsunami as things that might happen after an earthquake. Take things a step further and discuss the fact that there are other ways those things might have happened (a landslide can be caused by heavy rain, for instance), so correlation doesn’t necessarily prove causation.

Inventions That Changed the World

Explore the chain of cause and effect with this fun thought exercise. Start it off by asking one student to name an invention they believe changed the world. Each student then follows by explaining an effect that invention had on the world and their own lives. Challenge each student to come up with something different.

Critical Thinking Games

There are so many board games that help kids learn to question, analyze, examine, make judgments, and more. In fact, pretty much any game that doesn’t leave things entirely up to chance (Sorry, Candy Land) requires players to use critical thinking skills. See one teacher’s favorites at the link below.

“Judge a man by his questions rather than his answers.” – Voltaire

As critical thinkers, it’s our job to question everything, instead of just blindly believing what we’re told, but what kinds of questions should we be asking though?

What are the “right” questions to ask?

In this article I’ve compiled a list of 200+ of the very best critical thinking questions for almost any situation.

• Has the interview been edited to make the interviewee look bad, to paint them in a negative light?
• What additional questions would you ask the interviewee that the interviewer didn’t ask?

If you’re watching a group or panel discussion

Ask the other person:

• How did you determine that?

• What do you know that I don’t?
• Where am I wrong in my argument or rationale?
• What evidence would it take to change your mind, to convince you otherwise?

Statistics questions

“There are three kinds of lies: lies, damned lies, and statistics.” – Benjamin Disraeli

Ask yourself the following questions whenever you’re presented with any statistic:

• Who paid for the study or survey?
• Who conducted the study or survey? Does it come from a credible source?
• Why was the study or survey done? What is the likely agenda?
• When was the study done? Is the information outdated? Is it still relevant? Times change. Public opinion changes
• Who was polled? Conservatives or liberals? Men or women? Asians, Blacks, Hispanics or Whites? What age group? Gen X, Y or Z? How diverse was the group?
• How large was the sample size? How many people were surveyed? Is the sample size large enough? Is it qualitative, quantitative, or mixed methods? Was the sample size sufficient?  Was it  representative enough of the wider population? Did the participants come from different cultural and social backgrounds? How generalizable are the findings?
• What are the statistics measuring?
• How long did the information take to gather? Was it a 2 week survey? A 6 month study? A 10 year study?
• What questions were asked?
• How was each question asked? Were the questions leading or loaded or worded in such a way as to encourage a certain answer?
• What is the context of the survey?
• How was the research done? Phone, email, social media, face to face?
• What is the number as a percentage? e.g. 55, 000 Americans is 0.0167% of the population
• Is the percentage statistically insignificant? e.g. 500, 000 Americans might be addicted to Heroin, but as a percentage that’s ‘only’ (any number above one is obviously too high) 0.153% of Americans
• Do the author’s conclusions and the headline logically follow from the data? Or are they reading too much into the data? Find the raw data if you can. Don’t just accept and believe headlines for statistics. Make sure it says what the headline says it says. Statistical headlines are often used to suggest things the data doesn’t actually say
• Is the research confusing causation and correlation? Check out: spurious correlations for a perfect visual example of why correlation does not equal causation
• Has this study been peer reviewed by experts?
• Beware of unsourced statistics

“I can prove anything by statistics except the truth.” – George Canning 

Critical thinking about your life questions

“The unexamined life is not worth living” – Socrates

Short Answer Type Questions

1. Define crop along with examples

Answer:   Plants of same kind that are grown and cultivated at one place on large scale are called a crop. Some of the crop plants are wheat, rice, maize, sugarcane, cotton, vegetables, fruits etc.

2. Differentiate between kharif and rabi crops Answer:  

3. What do you mean by preparation of soil?

Answer:  Preparation of soil is a very important step in agriculture before cultivation of crops. It includes loosening of soil, removing weeds from the soil and levelling of soil before sowing of seeds. Loosening of soil improves the air circulation in soil and enhances the water retaining capacity of the soil.

4. Why loosened soil is important for cultivation of crops?

Answer:  It is necessary to turn and loosen the soil because only loose soil allows the roots to penetrate freely deeper into soil. The roots can breathe easily in loose soil. The deep roots hold the plants more firmly. The water also can reach easily up to more depth in loose soils. Microbes and worms can also grow in loose soil.

5. Write a paragraph in your own word on each of the following: (a) Tilling (b) Weeds

Answer: (a) Tilling:  The process of loosening and turning of the soil is called tilling or ploughing and is carried on by using a plough. Ploughs are made by wood or iron material, it is being used since ancient time for different purposes like tilling the soil, adding fertilisers to crops, removing weeds etc. this implement is drawn by a pair of bulls or other animals like camels, horses etc.

(b) Weeds:  Weeds are unwanted plants that grow along with crop plants and compete with them for water, nutrients, space and light, thus they affect growth of crop plants. Some of the weeds are poisonous for animals and human beings and they interfere even in harvesting of crop plants and the removal of weeds is called weeding.

6. Write shorts notes on: (a) Sowing of seeds (b) Threshing

Answer:  (a) Sowing of seeds:  One of the important part of crop production is sowing. Good quality seeds are selected and are sown in prepared soil with the help of various tools like traditional tools and seed drill.

(i) Traditional tools:  The shape of this tool is like a funnel which is filled by seeds, then the seeds are passed down through two or three pipes having sharp ends and these ends pierce into the soil and place seeds there.

(ii) Seed drill:  This tool is used for sowing with the help of tractors and it sows the seeds uniformly and at proper distances and depth, it also ensures covering of the seeds from soil after sowing, so that seeds could not get damaged by birds and by other organisms. Sowing by using a seed drill saves time and labour. In order to avoid overcrowding of plants it is very important to leave some space between two seeds. This also allows plants to get sufficient sunlight, nutrients and water from the soil.

(b) Threshing:  Threshing is the process of separating the grains from the straw and chaff. This is carried out with the help of a machine called combine which works as harvester and thresher both.

7. What are the advantages of a cultivator over plough for the purpose of ploughing?

Answer:  Ploughing by cultivators save time and labour as cultivator is driven by tractors whereas plough is driven by pair of bull.

8. How could you separate good and healthy seeds from the damaged ones?

Answer:  Take a beaker half filled with water and put some seeds into it and stir well, wait for some time. You will observe some seeds sink in water while some seeds float in water, damaged seeds become hollow and lighter and thus they float on water.

9. Write a short notes on tools used for sowing seeds.

Answer:  Tools used for sowing of seeds are: (a) Traditional tools:  The shape of this tool is like a funnel which is filled by seeds, then the seeds are passed down through two or three pipes having sharp ends and these ends pierce into the soil and place seeds there. (b) Seed drill:  This tool is used for sowing with the help of tractors and it sows the seeds uniformly and at proper distances and depth, it also ensures covering of the seeds from soil after sowing, so that seeds could not get damaged by birds and by other organisms. Sowing by using a seed drill saves time and labour. In order to avoid overcrowding of plants it is very important to leave some space between two seeds. This also allows plants to get sufficient sunlight, nutrients and water from the soil.

10. What are the advantages of a seed drill used for sowing?

Answer:  Advantages of seed drill are as follows: (a)  This sows the seeds uniformly at equal distance and depth. (b)  It ensures that seeds get covered by the soil after sowing. (c)  This protects seeds from being eaten by birds. (d)  Sowing by using a seed drill saves time and labour.

11. How could we supply nutrients to the soil?

Answer:  We can supply nutrients to the soil by adding manure and fertilisers. Manures are organic substances obtained from the decomposition of plants and animal wastes which provides lot of humus to the soil. It is very important for the healthy growth of plants, and Fertilisers are chemical substances which are rich in particular nutrients like nitrogen, phosphorus and potassium, they are produced in factories. Examples: Urea, NPK, Ammonium sulphate etc.

12. Differentiate between manure and fertilizers. Answer: 

13. What do you understand by manuring and what are the harmful effects of improper or insufficient manuring?

Answer:  Farmers add manure to the fields to replenish the soil with nutrients and to increase their crop production, this process of adding manures to the field is called manuring. Improper manuring results in poor development of crop plants and unhealthy crops.

14. How could we prepare organic manure?

Answer:  Organic manure can be prepared in fields. Dump plant and animal wastes in pits at open places and allow it to decompose by some of the microorganisms; the decomposed matter is used as manure.

15. What are the harmful effects of fertilisers?

Answer:  Harmful effects of fertilisers are as follows: (a)  The excessive use of fertilisers makes soil less fertile. (b)  It is also considered as one of the source of water pollution

16. What is crop rotation? How it helps in replenishment of the soil?

Answer:  Crop rotation involves growing two or more crops alternatively on the same piece of land. For example: after growing wheat for a season, farmers prefer to grow crop of legume family such as peas, gram and groundnut. These leguminous plants have nitrogen fixing bacteria on their root nodules. These bacteria convert atmospheric nitrogen into compound that can be used by plants. This makes the soil rich in nitrogen which is good for crops.

17. State advantages of manure

Answer:  Advantages of manure: (a)  Water holding capacity of soil is increased by adding manure to the soil (b)  It increases the total number of friendly microbes in soil and thus increases soil fertility (c)  By adding manure soil become more porous so that the exchange of gases becomes easy (d)  It improves the texture of the soil.

18. What is irrigation and its importance?

Answer:  Irrigation is the process of applying water to the crops artificially to fulfil their water requirements. The various sources of water for irrigation are wells, ponds, lakes, canals, tube-wells, and even dams. Water is very important for proper growth and development of flowers, fruits and seeds of plants, it plays important role in (a)  Germination of seeds (b)  Transportation of nutrients in different parts of plants (c)  Protects crops from both frost and hot air currents (d)  It maintains the moisture of soil

19. Why we should supply more water to crops during summer season?

Answer:  Because of the increased rate of evaporation of water from the soil and the leaves it is important to increase the frequency of watering in summer season.

20. Explain modern methods of irrigation.

Answer:  Modern method of irrigation help us to use water economically, it involves following methods: Sprinkler system:  In this system the perpendicular pipes with rotating nozzles on top are joined to the main pipeline at regular intervals when water is allowed to flow through the main pipe under pressure with the help of pump, it escape from the rotating nozzles, it gets sprinkled on the crop as if it is raining, sprinkler is very useful for sandy soil.

Drip system:  In this system water falls drop by drop just at the position of the roots. So it is called drip system. It is the best technique for watering plants, trees and garden. This system provides water to plants drop by drop, and water is not wasted at all

21. Why do we have to eat food?

Answer:  Food provides us energy. The energy provided by food is utilised by the organisms for carrying out their various body functions, such as digestion, respiration and excretion. We get our food from plants and animals.

22. Explain various types of crops.

Answer:  Crops are of two types: (a) Kharif crops:  The crops which are grown in the rainy season are called kharif crops (June to September). Paddy, maize, soyabean, groundnut, cotton are some of the major kharif crops.

(b) Rabi crops:  The crops sown in the winter season are called rabi crops (October to March). Wheat, gram, pea, mustard and linseed are some of the major rabi crops.

23. List various agricultural practices.

Answer: The agricultural practices are listed below:  (a)  Preparation of soil (b)  Sowing (c)  Adding manure and fertilizers (d)  Irrigation (e)  Protecting from weeds (f)  Harvesting (g)  Storage

24. What is plough?

Answer:  This implement is made of wood and iron. It is drawn by a pair of bulls or other animals. It contains a strong triangular iron strip called ploughshare. The main part of the plough is a long log of wood which is called ploughshaft. The plough is used for tilling the soil, adding fertilizers to the crop, removing the weeds and scraping of soil. 

25. What is hoe? What is its use?

Answer:  Hoe is a simple tool which is used for removing weeds and for loosening the soil. It has a long rod of wood or the iron. A strong broad and bent plate of iron is fixed to one of its ends and works like a blade. It is also pulled by animals.

26. Explain the preparation of manure by the farmers.

Answer:  Manure is an organic substance obtained from decomposition of plant or animal wastes. Farmers dump plant and animal wastes in pits at open places and allow it to decompose. The decomposition is caused by some microorganisms. The decomposed matter is used as organic manure.

27. What are fertilizers? How do they differ from manure on the basis of their formation?

Answer:  Fertilizers are the chemical substances which are rich in a particular nutrient. Fertilizers are produced in the factories while manure can be made by farmers themselves in the fields. Some fertilizers are urea, ammonium sulphate, super‑phosphate, potash, N.P.K. (Nitrogen, Phosphorus, Potassium). Fertilizers are used to get better yield of crops.

28. What is the role of water in the production of crops?

Answer:  Water is essential for plants. It helps in the germination of seeds because seeds cannot germinate under dry conditions. Nutrients dissolved in water get transported to each part of the plant. It protects the crop from frost and hot air currents. Water is important for proper growth and development of flowers, fruits and seeds of plants. Along with water minerals and fertilizers are also absorbed. Plants contain nearly 90% water. The time and frequency of irrigation varies from crop to crop, soil to soil and season to season.

29. Explain traditional methods of irrigation.

Answer:  The water available in wells, lakes and canals is lifted up by different methods in different regions, for taking it to the fields. Cattle or human labour is used in these methods. These methods are cheaper but less efficient. The various traditional ways are:

30. What is weeding? Why is it necessary?

Answer:  The process of removal of weeds is called weeding. Weeding is necessary since weeds compete with crop plants for water, nutrients, space and sunlight. Thus they affect the growth of crop. Some weeds interfere even in harvesting and may be poisonous for animals and human beings.

31. Explain the various methods of weeding.

Answer:  Farmers use many ways to remove weeds and control their growth. Tilling before sowing of crops helps in uprooting and killing weeds, which may then dry up and get mixed with the soil. The best time for the removal of weeds is before they produce flowers and seeds. The khurpi is used to remove weeds by uprooting or cutting them from time to time. A seed drill is also used to uproot weeds. Weeds are also controlled by using weedicides like 2, 4‑D.

32. Explain various methods of harvesting in our country.

Answer:  There are mainly two methods which are used to harvest the mature crops: (a) Manual : A device called sickle is used to harvest mature crops manually. (b) By Machine : A machine called harvester is also used to harvest crops. A machine called combine which is in fact, a combined harvester and thresher. This machine does both the functions of harvesting and threshing at the same time.

33. What do you know about Harvest Festival?

Answer:  After three or four months of hard work there comes the day of harvest. The sight of golden fields of standing crops, laden with grains fills the hearts of farmers with joy and a sense of well being. Men and women celebrate this period with great enthusiasm. This period of joy is called Harvest Festival. Pongal, Baishakhi, Holi, Diwali, Nabanya and Bihu are such Harvest Festivals.

34. How do the grains stored and preserved?

Answer:  Farmers store the grains in jute bags or metallic bins. However, large scale storage of grains is done in silos and granaries, to protect them from pests like rats and insects. Dried neem leaves are used for storing food grains at home. For storing large quantities of grains in big godowns, specific chemical treatments are required to protect them from pests and microorganisms.

Long Answer Type Questions

1. Describe various methods of agricultural practices involved in crop production and management.

Answer:  Various methods of agricultural practices involved in crop production and management are:

• Preparation of soil by tilling and leveling.
• Sowing of seeds into prepared soil.
• Adding manure and fertilizers for replenishment and enrichment of soil and healthy growth of crops.
• The supply of water to crops at appropriate interval called as irrigation.
• Protecting from weeds by using weedicides.
• Harvesting of crops by machines.
• Proper storage to protect them from harmful effects of pests and microorganisms.

2. Define irrigation and its various methods and explain its two methods which conserve water.

Answer:  Irrigation is the artificial application of water to crops at different intervals. The time and frequency of irrigation varies from crop to crop, soil to soil and season to season.

Two methods of irrigation are

1. Traditional method  of irrigation involves cattle or human labour and thus are cheaper than modern methods of irrigation, various traditional ways of irrigation are: (a)  Moat (pulley system) (b)  Chain pump (c)  Dhekli (d)  Rahat (Lever system)

2. Modern methods  of irrigation helps us to use water economically, it involves following methods:

Sprinkler system:  In this system, perpendicular pipes, having rotating nozzles on top, are joined to the main pipeline at regular intervals. When water is allowed to flow through the main pipe under pressure with the help of a pump, it sprinkles from the rotating nozzles. It gets sprinkled on the crop as if it is raining. Example:  It is used mostly on uneven land.

Drip system:  In this system water falls drop by drop just at the position of the roots. So it is called drip system. It is the best technique for watering plants, trees and garden. This system provides water to plants drop by drop, and water is not wasted at all. Example:  watering fruit plants, gardens and trees.

3. Describe the importance of weedicides, manures and fertilizers in good agricultural practice.

Answer:   Weeds:  Weeds are unwanted plants that grow along with crop plants and compete with them for water, nutrients, space and light, thus they affect growth of crop plants. Some of the weeds are poisonous for animals and human beings and they interfere even in harvesting of crop plants. Example:  Wild oat, grass.

Weedicides:  are chemical that are sprayed in the fields to kill the weeds, they do not damage the crops. Weedicides are diluted with water and are sprayed in the field by sprayer to kill the weeds. Example:  2,4-D

Manure and fertilizers  are added to the soil to replenish it with nutrients to ensure healthy growth of plants. Manures like animal waste, plant residues and fertilizers like urea, NPK are used for this purpose.

4. Explain harvest festivals.

Answer:  A Harvest Festival is an annual celebration that occurs around the time of the main harvest of a given region. The efforts of the farmer of past season borne fruit in the form of crop, laden with grain, at this point they celebrate harvest festival to express their joy and happiness. Special festivals associated with the harvest season are Pongal, Baisakhi, Holi, Diwali, Nabanya and Bihu.

5. Explain how continuous plantation of crops in a field affects the quality of soil.

Answer:  Crop rotation is the practice of growing a series of different types of crops in the same area in sequential seasons. Growing the same type of in the same place for many years in a row disproportionately depletes the soil of certain nutrients. With rotation, a crop that leaches the soil of one kind of nutrient is followed during the next growing season by a dissimilar crop that returns that nutrient to the soil or draws a different ratio of nutrients. For example, rice followed by cotton.

6. Differentiate between mixed cultivation and crop rotation

Answer:  In mixed cultivation, two or more different types of crops are sown in a particular field at the same time. For example,  pea plants can be grown in the same field along with a cereal like wheat.

Crop rotation is a practice of growing two or more dissimilar crops in the same field one after the other. The nutrient requirements of a particular crop are kept in mind when crops are grown on a rotational basis. For example,  it is a known fact that paddy uses up a lot of nitrogen from the soil. When planning for the subsequent crop to be sown, this fact is kept in mind. So leguminous plants like soya bean or pea are purposely sown so that this loss of nitrogen can be replaced naturally by them.

7. Write a brief note on ‘Animal Husbandry’.

Answer:  Animal husbandry is the management and care of farm animals by humans for profit. In animal husbandry, genetic qualities and behavior are considered to be advantageous to humans for further development. Animal husbandry has been practiced for thousands of years since the first domestication of animals. Humans are dependent on animals in many ways. The animals are domesticated by humans for many purposes. Depending on the usefulness of domestic animals they are categorized as:

• Meat and Egg yielding animals like pig, sheep, fish, poultry, goat and duck.
• Milk-yielding animals or dairy animals like cow, buffalo and goat.
• Wool and skin yielding animals like sheep, goat, camel, buffaloes and cow. Skins are used as leather for different articles.
