Reflection: Grappling with Complexity Modified Atwood Machine Lab - Section 3: Newton's Second Law Lab Data Collection

Next time I teach this lesson, I will definitely model how to complete the lab so students have a better understanding. I emphasized how to keep the controlled variables controlled but even after checking to make sure that a few students in the class could reiterate what they would be doing, many students did not understand the instructions of the lab. Next time I would include some written instructions as well as a written data table template of how to do each experiment and collect data so that students could refer to that instead of asking me multiple times how to do the lab. It made the data collection take quite a bit longer that I had anticipated.

Making sure students understand instructions is key!
