Potential vs Kinetic Energy

Here are a few more pics of students learning about potential and kinetic energy as well as how energy transfer works. Students engaged in a lab involving dropping different types of balls and recording data about their bounce heights. They also explored energy transfer by colliding marbles, and they explored energy concepts with rubber band cars.

Marble Collisons

Some days you wish every parent could see what is happening in their child’s classroom. Friday was that kind of day! Students were studying energy transfer: how a rolling marble transferred energy to a still marble on impact, and how the steepness of the incline affected that transfer. Every student was fully engaged. And then…after finishing, one group decided to try the same experiment but using a yardstick, thus changing the length of the inclined ramp. Other groups caught the vision, and suddenly my students became scientists excited to create their own experiments!

Testing rubber band powered vehicles on a carpeted floor. How does changing the amount of potential energy, change the amount of kinetic energy? How does today’s data compare to yesterday’s?
