Aluminum Foil Boats

Purpose: To learn about buoyancy forces through the designing of aluminum foil boats.

Learning Objectives:
1. Understand that buoyancy is the ability of an object to float in a liquid.
2. Understand that water has a force that counteracts gravity.
3. Explore how surface area impacts how much a boat can hold.
4. Understand that salt increases the density of water and thus increases an object’s buoyancy.
