In this activity, learners make "solar cookies," edible models of the Sun's outer layers using sugar cookies and toppings.

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 explore how eating unhealthy food can damage a heart and arteries.

In this quick activity, learners drink Avogadro's number worth of molecules - 6.02x10^23 molecules!

Learners mix liquid water with solid cornstarch. They investigate the slime produced, which has properties of both a solid and a liquid.

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

In this activity, learners make a yeast-air balloon to get a better idea of what yeast can do. Learners discover that the purpose of leaveners like yeast is to produce the gas that makes bread rise.

In this activity, learners use water, oil, and food coloring to observe a chemical reaction that creates a shower of colors inside of a glass.

In this activity, learners create a necklace of wheat germ DNA. Learners add alcohol to wheat germ so that the DNA clumps together.

In this chemistry activity, learners prepare two petri dishes, one filled with water and one filled with milk.

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 hands-on activity, learners make the world's simplest Cartesian diver, using only a plastic bottle, some water, and a condiment packet.

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

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

Learners combine hydrogen peroxide with three different forms of potato: raw chunks, ground chunks, and boiled chunks.

This simple and engaging astronomy activity explains nuclear fusion and how radiation is generated by stars, using marshmallows as a model.
