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.

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

In this activity, learners explore the forces at work in water. Learners experiment to find out what happens to pepper in water when they touch it with bar soap and liquid detergent.

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

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

In this physics demonstration, learners are challenged to insert a straw the furthest into a potato.

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 test what happens when they put baking power on different frozen liquids.

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

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

In this sunny day activity, learners compare how a cup of water and a cup of tonic water reflect or refract light in the sun.

Make snack time into measuring time and learn to read Nutrition Facts labels. Try this when you’re using “pourable” foods, such as cereal, yoghurt, or juice.

In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.

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

In this chemistry activity (page 5 of the PDF), learners will see that chewing is more than just the crushing up of food; there is actually a chemical change going on at the same time.

In this activity (2nd activity on the page), learners explore how the nose is responsible for part of the flavor we taste in food.

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

In this activity, learners mix water, cooking oil, and liquid food coloring to create beautiful colored designs in a cup. Use this activity to explore liquid density and solubility.

In this activity (4th activity on the page), learners test to see if saliva is necessary for food to have taste.
