How are they the same?
How are they different?
One floats and one doesn't! Which is which?

Great for teaching the skills of observation and deduction! Although these two shiny, metal spheres have about the same mass, one has a diameter of 2.86 cm and the other a diameter of 12.7 cm making their densities vastly different. Seeing the large one float in water seems unbelievable! Students can't put these down. Great for teaching that density depends on BOTH mass and volume. Another NSTA best seller! Bowl not included.

Density Identification Set

Students try to identify each of 15 different samples by determining their density.

Density Mystery Set

Ask students to determine the density of 15 identical looking, black plastic specimens of various sizes. Results will vary (hopefully)!

Density Paradox (set of two)

This is an awesome discrepant event for your most advanced 'density' students! Great for demonstrating how temperature can affect an object's density!

Density Sphere Experiment Kit

Designed to permit students to discover and apply concepts of density and buoyancy.
