In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.

Learners design, build, and test models of "dragon boats" made from up to three milk cartons.

In this hands-on activity, learners will construct a scuba diver that can float in order to explore how sea creatures stay neutrally buoyant in the ocean and to see what kinds of forces might be influ

Learners create beautiful fluid motion. They explore fluid dynamics, surface tension, solubility, and buoyancy while mixing liquids together.

The goal of this activity is to design the fastest sailboat or one that carries the most treasure.
