Day 42: Hoverpucks

hoverpucks

(double period)

First period:

Bowling Ball Debrief #1-5 only on Whiteboards

–> 2 students still thought that an object in space would eventually slow down (“loses energy over time” , “loses force”) while other students rightly said that w/o friction it would keep moving.

So we played with the hoverpucks to TEST a hypothesis:

* If it was “losing force,” then it would slow down even in a frictionless environment.

Kids saw constant speed. I talked about how friction was like tiny mallet taps when the bumps in the floor and ball hit each other.

2nd Period:

Introduced Unit Notes sheet — a way to keep track of key concepts, ideas, equations, etc. from each activity.

Discussion Notes for Activity #1 Bowling ball & Mallet — speed up (tap same direction), slow down (tap opposite direction), steady speed (no taps -or- tap same-opposite), friction vs. no friction

Finished up the period by riding the large hovercraft!
