Today we explored more about wheels. When asked about what wheels do, the children said that wheels “move us” and that “they take us from one place to another.” We then created our own vehicles, talking about how they need wheels as well as axles to work.
Last week we explored the importance of wheels and how they make things move easier. This week, we learned about a simple machine called a lever. In our story, the lever was a see-saw and it had a rigid bar that rested on a sturdy object called a fulcrum. A lever can lift or move things up and down.
The children used their body weight experimenting with one and then two feet to move a bean bag using our simple machines. They noticed that our boards in class were a lever, just like the see-saw in the story. They were also able to find the fulcrum and see that it wasn’t in the middle of the bar.
