At the end of our unit on sinking and floating, our lab is building lightships. We read the book Lightship, by Brian Floca to go along with this engineering challenge.
We have to make sure our lightships float, but also stay upright. We learned what happened to a boat that was too top-heavy - it sank!
When we started building our ships, we had to choose a material or a shape that would float and be stable, and we needed to include an anchor to keep it in one place. Here's what we came up with!
