Stacked Ball Drop - A Physics Lesson

The Physics Girl is a great YouTube channel that recently appeared as a suggestion while I was browsing the ASAP Science channel. The Physics Girl is Dianna Cowern who produces short physics lessons for students of all ages. Stacked Ball Drop is one of the videos that caught my attention while I was browsing her channel.

In the Stacked Ball Drop Dianna shows viewers that when one ball is placed on top of another and then dropped the ball on top bounces higher than it would if it was dropped alone. Dianna then goes on to explain the physics that is involved in a single ball bouncing as well the physics of two or more balls stacked on top of each other being dropped and bounced. That explanation transitions to how the concepts in the stacked ball dropped are analogous to the formation of super novas.


Applications for Education
This video demonstrates an excellent science lesson for students. After watching the video or a portion of the video you could have students write predictions for what they think will happen if they stack more balls and or use balls of different sizes and densities. Then let them go out and conduct the experiment and record their results.

To create a flipped lesson based on this video try using Vizia, VideoNot.es, or EDPuzzle.
