The popular science toy, the Cartesian diver, is not only fun to play with, it also connects to at least five scientific principles and laws. • Archimedes' Principle • Pascal's Principle • Boyle's Law • Newton's First Law of Motion • Pressure as a Function of Depth in a fluid A Cartesian Diver is easily made from a 2-Liter plastic bottle and a glass eyedropper. Making a working Cartesian diver is a 100% successful activity.

This hands-on activity reveals the chemistry that describes the well-known baking soda and vinegar chemical reaction. Students observe the reaction and then model the balanced chemical equation with a set of Chem Cards. A great introduction to the subject of chemistry.

This hands-on activity teaches students how to apply Newton's third law of motion to the freefall portion of a real skydive and the freefall motion of a paper skydiver. Instructions for cutting, folding and dropping the paper skydiver are printed on the student page.
