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!

More Potential and Kinetic Energy

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?

Spaghetti Engineering Challenge

The first day of the 2018-19 school year was exciting. Our STEAM challenge: Groups of 4 had 16 minutes, 20 spaghetti noodles, and 1 yard of masking tape to build a tower that would support a jumbo marshmallow on the top.
