Friction Experiments

We had lots of fun in Room 8 this afternoon learning about friction.
We have lots of questions...

What objects have most friction? Why?

What materials (what things are made of) have the most friction? Why

How can we increase or decrease the friction of objects?

Hopefully we can answer these over the next couple of weeks.

We found some shoes went down the ramp faster than others.

So then we had a rubber race! Some rubbers were super speedy. Others hardly moved at all. Why do you think this was?

                                

How could we make the rubbers move faster? (Post a comment)
