In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

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

Learners create three solutions with different levels of salinity. They compare the density of these solutions by coloring them and layering them in a clear plastic cup and in a soda bottle.

Based of the The Tech Challenge 2015, learners will engage in two mini-design challenges related to seismic engineering.

In this two-part activity, learners investigate buoyancy, density and surface area as well as biodiversity and the relationship between the structure and function of organisms.

Design a vessel that tests the limits of wind power given a set of off the shelf and recycled materials.

In this physics activity, learners will explore buoyancy.

In this hands-on activity, learners make the world's simplest Cartesian diver, using only a plastic bottle, some water, and a condiment packet.

In this demonstration, adult learners create a lava lamp using beer and nuts! Use this pub-themed activity to demonstrate the effects of buoyancy and bubbles.

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