We made Cartesian Divers. We saw that squeezing the bottle changed the size of the bubble in the diver and caused the diver to sink. A lot of really tricky science can explain this but just understanding a little bit about density can help the kids to figure out how the divers sink and float.

We made foil boats and tested how much weight they could hold. By observing their boats and the boats of their classmates, students could make suggestions about how to make a better boat. This was quite exciting and it seems like students could build boats all term.
