Dynamic Demo of the Week-Tennis Ball Molecules

I use tennis balls to demonstrate lots of things in my science classroom. Here I use 2 balls to demonstrate something we cannot even see- what happens when air is heated. Don’t worry about how simple it is; that’s how air molecules really behave.

This demo is an excerpt from an Interactive Science Lesson called “Bag Balance“.

Time-Saving Teacher Tip-Clear Instructions

Would you be shocked if your students went to a workstation and actually knew what to do? Write out what it is they are supposed to do (“Take 3 rubber bands”, “Fill beaker halfway with water”, etc.…) on a piece of paper and tape it down at the station like a sign. No more confusion, no more repeating.
