In this activity, learners use three types of cheesy snacks--cheese balls, cheese puffs, and Cheetos--to learn about polymers.

In this chemistry activity (page 3 of the PDF), learners will learn about crystals by growing their very own.

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

In this activity, learners use oil, water, food coloring and antacid tablets to create a bubbling lava lamp. Use this activity to introduce concepts related to density, hydrophobicity vs.

In this activity, learners make instant ice cream without using a freezer.

This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells. It includes an optional test for the presence of DNA.

In this activity, learners make prisms from gelatin. Learners then shine light through the prisms and discover what happens. This activity introduces learners to the idea of refraction.

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

In this optics activity, learners use a shoebox, colored cellophane and sunlight to "change" the colors of gumballs. Learners will be surprised when the green and blue gumballs appear black!

In this activity on page 7 of the PDF, learners follow a recipe to make a dough similar to the clay artists use to make sculptures.

In this activity, learners examine baking powder, a combination of three powders: baking soda, cream of tartar, and cornstarch.

In this biology activity (page 3 of the PDF), learners will explore how plants turn sunlight into food through a process called photosynthesis.

This hands-on activity lets participant explore chemical reactions as they create a soda explosion with lots of bubbles. The bubbles in soda are made of carbon dioxide gas.

In this activity, learners add food coloring to hot and cold water to see whether heating or cooling affects the speed of water molecules.

In this physics demonstration, learners are challenged to break a raw egg just by squeezing it. Learners will be shocked by their inability to complete the deceivingly simple challenge.
