Unit 2: Fluids (revised 2010)

In this challenge activity find out if you can get an egg to float. Learn how the density of matter affects the buoyancy of objects.

It’s not easy to dive deep underwater. How do divers get down deep? Learn how scuba divers manipulate density to move up and down in this hands on activity.

Explore the forces of gravity and buoyancy while designing a raft to hold the most weight possible.

Use a pop bottle and other everyday materials to create a rocket that you can launch outdoors.

Build a vortex cannon and discover how fluids (liquids and gases) can move in unique ways due to their physical properties.

Have you ever been on a ship and wondered how you’re staying afloat? The answer is buoyancy!
