Students determine whether a liquid will sink or float in water by comparing its density to the density of water.

This experiment allows you to dramatically demonstrate the different densities of five different common household liquids.

This experiment demonstrates the density of selected liquids.

Discover how the molecular make-up of water affects its density.

Learn how the molecular movement in different temperature water affects the density of the liquid.

Demonstrate the effect that dissolving different amounts of salt in water has on the density of the liquid.

In this lab experiment, students will use 4 solids and 6 liquids to create colorful, layered rows demonstrating that less dense materials will float on top of the more dense materials.

By making oil float on water--with the help of other ingredients--students can create a lava-lite effect.

Learn about the layers of the Earth.

Investigate the science behind this age old question. Find out the role density and polarity play in the liquids.
