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

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

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