Sink of Float?

This week the children were curious about what types of things sink in water and what types of things float in water. We filled up a large tub, and got to work. We experimented with water beads, plastic animals, q-tips, puff balls, and much more!

We found that heavy things tend to sink while lighter things tend to float. We observed that items that were filled with air were more likely to float then items that took on water.
