In this activity, learners sublimate dry ice and then taste the carbon dioxide gas.

In this activity (4th activity on the page), learners use their sense of smell to rate and arrange containers filled with different dilutions of a scent (like cologne or fruit juice) in order from wea

In this online activity, learners experience the thrill of pickle making, and explore how a cucumber becomes a pickle.

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

In this optics activity, learners explore how they can make gelatin stop light, but not stop them from seeing fruit suspended within.

In this activity, learners mix up a bubbly brew and examine density. Learners explore how they can make different materials fall and rise in water using oil, water, and salt.

In this quick activity, learners break the tension that happens when water develops a "skin." Learners use water, pepper and some soap to discover the wonders of surface tension—the force that attract

This is a series of three quick science activities to do with a spoon, knife, and fork. In the first two activities, learners use the flatware to explore optics, mirrors, reflection, and distortion.

In this activity, learners construct drums out of everyday containers (like bowls or food containers) and shrink wrap. Learners use a hair dryer to affix and tighten the shrink wrap to the container.

In this chemistry activity, learners use spaghetti to explore density and chemical reactions.

In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.

In this activity, learners test what happens when they put baking power on different frozen liquids.

In this activity, learners use gelatin as a lens to investigate the properties of laser light.

In this two-part activity, learners use household items to smell the difference between some stereoisomers, or molecules which are mirror images of one another.

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.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.

This activity teaches combustion as the interaction of a fuel source and oxygen.
