Good evening!
Today in Science we made some boxcar racers. Students constructed boxes out of card stock and we attached wheels and axles to the boxes. We used plastic and paper straws, as well as more card stock for the wheels. Students put the plastic straw through their box, in order to create a smooth cylinder for the axle to rotate within. Then we placed the paper straw through the plastics straws, creating a freely rotating axle. We then attached wheels to our boxcars. Students were asked to answer the following question “What is the most efficient axle position?” By changing our tire positioning, we were able to determine that having the axle positioned in the middle of the wheel is ideal for creating a simple machine that works with the least amount of effort.
