Create a chemical reaction that makes cheese! This hands-on activity demonstrates that molecules and atoms are tiny particles that make up everything around us.

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

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 follow a recipe to make hollandaise sauce. Learners discover how cooks use egg yolks to blend oil and water together into a smooth mix.

In this activity, learners measure the amount of carbon dioxide in a carbonated drink.

In this activity, learners touch supercooled water drops with an ice crystal and trigger the water drops to freeze instantly.

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

In this activity, learners conduct an experiment to explore how water flows up from a tree's roots to its leafy crown.

In this "Sid the Science Kid" activity from Episode 108: My Ice Pops, learners observe reversible change while thinking about ways to make ice melt.

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

In this activity, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.

In this tasty activity, learners make their own ice cream any day of the year in an exploration of heat and cold. Highlights include freezing and melting and the transition from liquid to solid.

In this delicious activity, learners get to make, taste-test and compare their own "brands" of homemade strawberry ice cream.

This fun video explains how to make a batch of oobleck (or slime) and why this special substance is known as a "non-Newtonian" fluid. Watch as Mr.

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 chemistry activity, learners use the lowered freezing point of water to chill another mixture (ice cream) to the solid state.

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

In this activity, learners cut wells in JELL-O© and load the wells with different detergent solutions.

In this chemistry activity (page 1 of the PDF), learners will observe a physical change.

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