Wheels VS Rollers

In Science we experimented with rollers.  We discovered that they are hard to steer, you need a lot of them to go a long distance, and they have no axle.  We discovered that rollers REDUCE FRICTION, making our work easier.

Erin was a good sport and allowed us to push her across the floor in the basket.  Jake said it was hard work.  Then we put her on the rollers and Mrs. Campbell could easily push her across the floor.  :-)
