The task is to use one of the PhET simulations to design an online lab that can be used to teach certain concepts to students.
You will probably need to do research on your own to better understand the concept you are attempting to teach (something you will probably have to do when you are a teacher).
USE THIS SIMULATION I PREFER: https://phet.colorado.edu/en/simulations/pendulum-lab
I attached a sample model as well.
Your lab lesson should link to the simulation you are using.
Your lab lesson should also explain clearly how to use the simulation so that students can make the proper observations and complete it. For example, which boxes need to be checked so that the data the students need will be displayed. You should also include some explanation of the concept being taught by the simulation.
There should be at least 10 questions; at least two of which should require a calculation and the rest should be conceptual questions that requires the student to interpret what they see in the simulation.
