The Case of the Mixed Up Sub
- Level: High School
- Topic: Density
Description:
This activity works best with curricula dealing with the density of fresh & salt water. The activity also could be adapted to fit a biology or physics class. Students will develop a basic understanding of the density differences between fresh and salt water by first determining the properties that require a submarine captain to keep a close watch on the surrounding changing marine environment, then using these properties to design and build a pseudo-sub capable of being neutrally buoyant in fresh water. They will then transfer this fresh water sub into a marine environment where they will have to determine and carry out changes to the sub's design, to make it neutrally buoyant in sea.
