It has been fun this past week as we investigated ways things roll.
We started by rolling wheels and created our very own wheel systems. Did you know that if you have two wheels that are the same size, the wheel system rolls straight. If one wheel is smaller, then the wheel system will roll off to the side of the ramp.
We tried rolling cups too! They rolled off to the side as well, because they have one big end and a small end. To make the cups roll straight we had to join them together in the middle with tape and have the same size on both ends.
If we added weight to the cups, they rolled slower and faster and some bumped up and down.
WOW! we learned a lot about rolling!
