We love some LEGOs around here. They are played with every day. Thus when it was time to talk about levers as part of simple machines for science, I knew we had to use LEGOs.
I started the lesson by giving the boys the definition of levers and talking about the three parts of a lever. I was surprised how easily they understood the difference between the effort and the load and how they act on the lever. Next, I introduced each type of lever and drew an example for them on a whiteboard. I then asked the them to create an example of the lever out of LEGOs.
Thing 1 was able to create each lever, a much better lever than I did, in less time.
After each type of lever was built I had the boys draw an example on a simple worksheet I created to further reinforce the concept. At this time we also talked about real life example of each type of lever. Thing 1 blew me away with the examples he came up with there were some I didn’t even think about. For example, he realized that the act of him throwing a ball in a windmill fashion was similar to a third class lever.
How have you used LEGOs in your school?
