Watch carefully. One thing stays on top of the water. One thing goes down. Why do you think that happened?
Look at each thing I hold up. Thumbs up if you think it will float and stay on top. Thumbs down if you think it will sink and go down to the bottom.
Guess first, then we drop and watch. We will start with the big log and the small nail.
At the water tray, pick one thing. Guess float or sink first. Then put it in and watch. Try the next one the same way.
Use the dry things in the tub, the ones that stayed dry. Put the ones that floated in the float hoop. Put the ones that sank in the sink hoop.
