Week 8 – Buoyant Boats Part 2 – The Submarine

Last week teach about the concept of buoyancy. We can extend last week’s inquiry to be a bit deeper.

Extended Inquiry Question: Can we manipulate (control) the buoyancy of your submarine to float in the middle of the tank? Ie between the bottom and the top?

You’d be surprised at the answers. Most students said yes right away and were eager to test it out!
