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

An experiment in buoyancy which involves making raisins float by using carbonated soda pop. Students then try the same test with other materials. Instructions for making one's own carbonated liquid are also provided.

Learn about density in this hands-on science experiment. Includes full list of materials, procedures, and scientific explanation of what makes an object float or sink. [PDF]

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.

By choosing the mass, size, and time, students can experiment with whether the block floats or sinks in this simulation. Students have the option to display the forces and add a second block to the tank. Density is also shown to allow...

Experiment with a helium balloon, a hot air balloon, or a rigid sphere filled with different gases. Discover what makes some balloons float and others sink.

Students studying buoyancy will better understand its concepts with this virtual experiment using various balloons and testing what makes them float or sink.
