Balance and Motion

Wow, things are really rolling along in Room 223...We just began a science unit on how objects move and balance. We are observing and experimenting with forces like pushing and pulling, gravity, balancing points, and counterweights.

We began our investigations by using some simple tools: a cardboard ramp, a plastic axle, and two different sized wheels. During our experiments we noted what happened when big and little wheels were pulled along by gravity. Ok, some groups added pushing forces as well. Zoom, zoom, zoom.

The last couple days we have been exploring balance and balancing points. Who among us would have predicted we could balance a crayfish on its nose? Sound fishy? You're right. We used a tagboard cutout of a crayfish instead of the genuine article. While the crayfish was fairly stable, we discovered it became more stable when we added counterweights. You probably know the counterweights better as clothespins.

Each day we explore a little, question a little, talk a little, and read and write a little about balance and motion. In these processes, literacy helps us complete our work as scientists, engineers, problem solvers. As always, the learning never seems to stop. So, here's to balance. Here's to motion. And here's to Seconds!
