Did you know...
and...
Just like before the children learned these facts through reading, discussing, and experimenting.
Here is some of what we did:
- We rubbed our hands together.
- We watched things slow down.
- We rolled items down a ramp and saw which "floor" had the least amount of friction (because it went the farthest!)
- We leaned on things to show friction at our feet keeping us standing.
- We rolled and pushed things across the floor to see the amount of friction it created (see below)

Through all of this we learned... friction is a force that happens when things rub together or touch. And it slows down movement.
