Cartesian Diver

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. This highly visual demonstration works best when learners can try moving the diver up and down themselves. This activity can also be related to how animals, like whales, dive in deep waters. This activity guide includes a helpful video that demonstrates each step of...
