Students design and construct a boat out of aluminum foil and a few other simple materials. The boats then be tested by floating them in water, then adding mass until they sink. They explore the various shapes of boat construction.

Students research inventors and inventions and their impacts. In this invention lesson, students research inventions and their affects in good and bad ways.

Pupils study the properties of fluids under different circumstances.  In this pressure fluids instructional activity students view a demonstration, complete an activity and describe what they learned. 

In this lesson, students will investigate why the Cartesian diver dives and rises in a 2 liter bottle. They will also, through their own discovery, come up with a question and then change one variable and record their results. Students...

Students observe Pascal's law, Archimedes' principle, and the ideal gas law as a Cartesian diver moves within a closed system.

This site presents a procedure for creating a cartesian diver, a miniature submarine which rises or sinks depending upon the water pressure within a closed bottle. The site also introduces basic concepts of water and air pressure.

In this lab, students will have to build a Cartesian diver to bring to class to race. I do this as an introduction to the gas laws, specifically Boyle's Law which deals with volume and pressure of gas at the same temperature. The...

This PBS site shows users how they can make their own cartesian divers, discover how it works, and have some fun at the same time.

Use a condiment packet as a Cartesian diver to show how pressure changes cause the "diver" to float, sink or hover.

A simple experiment in buoyancy where you discover how to make a packet of sauce or candy float or sink at will, and why you are able to do this.

Try out these experiments you can do with items you might already have around the house: "Two Ball Bounce," "Cartesian Diver," "Straw Flute," "Bernoulli Ball," and others. Two experiments, "Imploding Pop Can" and "Balloon in a Bottle,"...
