Today, AP Physics 2 students had the first opportunity to modify an existing computational model to prepare for tomorrow’s lab practicum. Tomorrow’s lab practicum is to predict where on the floor to place a cup such that the cup catches the water exiting from a 2L-bottle filled to the specified level and placed the specified distance from the floor. The computation model that I provided implements projectile motion and provides the framework for modeling the bottle and water. Students have to add the physics to calculate the initial velocity of the water. I also emphasized the importance of verifying your model against a known outcome before using it to predict an unknown outcome. Students are using Friday’s quiz as a test case for their model and verifying the prediction of the model against their hand calculations. While this lab practicum doesn’t require the use of a computational model, it is another representation in which the students demonstrate their understanding.

We will see how wet the floor gets tomorrow!
