## Reflection: Performance Tasks A Collision Lab - Section 3: Collision Lab Activity

This student lab sample is a good effort and shows me the group understood how momentum conservation was applied. My only critique of this final document is that the group didn't calculate the percent error and the explanations are a bit weak in the conclusion. The AP Physics 1 exam emphasizes justification of evidence and results through error discussions, so it's my goal to get students to practice this process in as many formal assessment opportunities as possible.
