“We’ve been making toboggans in Cheryl’s class with Kai, one of the dads of a kid in our class. We’re making two toboggans. Right now we’re making the stringers. The stringer is a piece of wood that goes down the middle of the sled. It used to go down the whole length, but now it only goes part way. The stringer is used for strength and it makes the toboggan stiffer.
Because we’re making toboggans we’ve been learning about friction, like how it slows you down, and gravity, and some of Newton’s Laws, like: A body in motion tends to stay in motion unless acted upon by another force. And: For every action there’s an opposite and equal reaction. For tobogganing, this would be like when you push off and you keep going forward. We’re making the toboggan out of polyethylene. Polyethylene is really slippery so it reduces friction and makes the toboggan go faster. It is also made from recycled milk jugs, there’s a fun fact for you!
When they’re done we’re going to take them out to test them at Rosemont Golf Course, or somewhere with a big hill.”
