This is written as a static display, but can easily be adapted to a hands-on experiment for learners to conduct.

In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.

In this activity, learners explore the different salinities of various sources of water by taste-testing.

Learners see that a carrot slice sinks in fresh water and floats in saltwater.

In this activity, learners explore what happens when polarized white light passes through a sugar solution.

In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.

Learners mix a solution containing luminol and copper with a fake blood solution. A chemical reaction between the luminol solution and fake blood (hydrogen peroxide) show learners a blue glow.

In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.

In this activity, learners investigate diffusion by creating underwater "fireworks" using food coloring, oil and water.

In this activity, learners explore how salt water freezes in comparison to fresh water.

This series of chemistry stations is designed to accompany the PBS documentary about African-American chemist "Percy Julian: Forgotten Genius." Each of the six stations features either a chemical or p

Learners observe a sealed container holding a clear colorless liquid. They shake the container and the fluid turns blue. When allowed to sit for a few moments, the fluid turns colorless again.

Learners use a universal indicator to test the amount of sodium hydroxide needed to change the pH of plain water compared with the amount needed to change the pH of gelatin.

In this chemistry demonstration, learners investigate the factors that increase the rate of dissolution for a solid.

Learners use a mortar and pestle to extract clove oil from cloves using denatured alcohol. They put this oil on paper, which they can take home.

In this investigation of reaction kinetics, learners alter the amount of iodate solution mixed with the same amount of starch solution.

Learners test solutions of water, sugar, salt, and hydrochloric acid for electrical conductivity. They immerse leads from a lighting device (a battery pack connected to an LED) into each solution.

Learners add acid rain (nitric acid) to two cups that represent lakes. One cup contains limestone gravel and the other contains granite gravel.

In this activity, learners explore the properties of metals at four stations. The stations include A) Magnetism and Breakfast Cereal; B) Conductivity of Metals; C) Alloys; and D) Metal Plating.

In this quick activity, learners observe how salinity and temperature affect the density of water, to better understand the Great Ocean Conveyor.
