Resource Type: Virtual Labs

The Virtual Lab is an online simulation of a chemistry lab. It is designed to help students link chemical computations with authentic laboratory chemistry. The lab allows students to select from hundreds of standard reagents (aqueous) and manipulate them in a manner resembling a real lab. More information and offline downloads .

Pre-Lab Primer

This pre-lab assignment is an individual assignment to be completed on your own with the help of the "Prior Knowledge" links at the top of this page. All work must be in your own words. Do not copy and paste information from the internet. The assignment will be due 10 minutes before your lab begins.  Late work will not be accepted.

The document below is a preview only. Please do not try to screenshot or print it off. You will be able to find your assignment to work on in your Google Classroom.

Interactive Element

In-Lab Assignments

Group assignment.

Using Zoom Breakout rooms, you will work collaboratively with your group on a Google Doc worksheet called  "Gas Laws Group Worksheet" . Each person can type in this document at the same time. Remember, part of your grade comes from your participation during lab, so there will be a Peer Evaluation this week. Make sure you are contributing to discussion and to the completion of the worksheet. The worksheet will be due by the end of your lab session, and late work is not accepted. Be sure to turn your assignment in on Google Classroom.

Individual Graphing Assignment

After your group has finished the first assignment, you will work individually on a graphing assignment using real experimental data. Your lab instructor will assign a data set to you that can be found on a Google Sheet linked within the assignment. Make sure you open the correct tab since there are five different sets of data!  You will need to copy and paste this data into your own Google Sheet to make some calculations and build the graph for this assignment. Save your Google Sheet! You will also use it for your Post-Lab Problem set to make additional calculations and graphs. This worksheet will be done by the end of your lab period, so make sure you turn it in on Google Classroom. Late work will not be accepted.

Post-Lab Problem Set

After you have had a chance to work on the data analysis with your group during lab, you will be given the  Gas Laws Post-Lab Problem Set.  This is an individual assignment that must be completed on your own, and it builds off of your Individual Graphing In-Lab Assignment. You will need to use the same data set that your instructor assigned to you, and the same Google Sheet that you worked on during lab. You will have a little bit of extra time for this Post-Lab Problem Set: it will be due by 8:00 am two days after your lab meets. For example, if your lab is on Monday, the Post-Lab will be due on Wednesday at 8:00 am. If your lab is on Tuesday, the Post-Lab will be due on Thursday at 8:00 am.  No late work is accepted.
