Activities (2)

Will the egg break? part of comPADRE Pedagogic Library:Interactive Lectures:Examples
This is a discrepant event that can be used to help students understand applications of the momentum-impulse theorem. Students are first asked to predict and hypothesize what will happen when an egg is thrown into a sheet. After sharing predictions and hypotheses, a volunteer student will throw the egg into the sheet. Other students make observations and craft explanations of what happened to explain why the egg does not break when it hits the sheet but does break if thrown at a wall. Students will then be asked a series of guiding questions to help them challenge misconceptions and sharpen their understanding of momentum and impulse.

Science on a Skateboard - Applications of Newton's Third Law part of comPADRE Pedagogic Library:Interactive Lectures:Examples
This is a discrepant event demonstration that can be used to help students begin to understand some applications of Newton's Third law of motion. In this activity, students are asked to predict what would happen if you were sitting on a low friction cart and threw a heavy medicine ball off the back. Students will apply knowledge learned from this demonstration to help them understand basic rocket propulsion.
