Boat Float

We have been learning about solids and liquids.  We experimented with testing many objects in water to see what would sink and what would float.  We also tested all kinds of plastic bowls and cups to see which one would make the best boat:

dollar section at target several years ago

 "the winner" -  We decided it must be because it is wider and has straight sides.
This really helped the students see why a boat must be balanced.

Next, the students made their own foil boat! 

Each student recorded how many frogs their boat held.

They also recorded this in their Learning Log!

The winning boat!!

It held 164 frogs!!!
