What Are Scientists? The class then drew a picture of themselves as scientists in a field that interested them. The pictures were quite cute. We have some budding scientists!

We talked about the fact that scientists study everything. They ask lots of questions. They do experiments, make hypotheses, discuss their findings, and ask more questions!
We have been experimenting with forces - push and pull. We have talked about friction and gravity.
Yesterday we did experiments with dropping 2 objects and making predictions about which would fall faster? The items included ping pong balls, marbles, a shotput, erasers, pencils, a feather, paperclips, and paper.

| Finch records her results on her data sheet. |
Then, three third grade classes (Mr. Kuehl's, Mrs. Sheehan's, and our own) met together to discuss our results. We learned about Galileo and his work in the 1600s with gravity.

We finished by watching a video of an astronaut conducting Galileo's experiment using a feather and a hammer on the moon.

After our experiments we wrote about what we learned from falling objects. Here is what we concluded.
