This lesson focuses on how materials behave differently as their surface area increases.

In this activity on page 4 of the PDF (Get Cooking With Chemistry), learners investigate ingredients that combine to produce gas bubbles.

In this activity on page 2 of the PDF (Get Cooking With Chemistry), learners conduct chemical tests on certain powders used in cooking.

In this activity, learners discuss how life is defined and conduct a simple experiment, looking for signs of life in three different “soil” samples.

In this chemistry activity, learners perform three chemical reactions in a sealed zip-top bag. Learners will record their observations and classify the changes as chemical or physical.

In this activity, learners test exhaled breath for carbon dioxide and learn how to use an indicator as a simple way to measure pH.

In this activity on page 6 of the PDF (Get Cooking With Chemistry), learners investigate yeast. Learners prepare an experiment to observe what yeast cells like to eat.

In this activity on page 6 of the PDF (Chemistry—It’s Elemental), learners explore some of the properties of copper using a few common household ingredients.

In this activity on page 8 of the PDF, learners investigate vitamin C. Learners conduct a chemistry experiment to determine if Tang drink mix or orange juice contains more vitamin C.

In this chemistry activity which should only be done under adult supervision (page 10 of the PDF), learners will create an exothermic process by making Sodium Acetate.

In this activity, learners create and reveal secret messages written with invisible ink! The invisible ink is actually a baking soda solution, and the magical revealing liquid is fruit juice.

In this activity, learners experiment with hydrogen peroxide, vinegar, yeast, and baking soda to produce hot and cold reactions. Use this activity to demonstrate exothermic and endothermic reactions.

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 (located on page 2), learners will construct tiny model geysers out of film canisters, warm water, and antacid seltzer tablets.

Learners place water and part of an antacid tablet in a film canister. The reaction creates a gas reaction that launches the film canister like a rocket.

In this activity, learners construct and launch rockets using simple materials and their understanding of chemical reactions.

In this fascinating and fun experiment, learners use chemistry to identify a mystery powder and to solve a "crime," a process similar to that used by real forensic scientists.

In this chemistry activity, learners transform two ingredients (4% polyvinyl alcohol solution and 4% borax solution) into gooey slime.

Learners mix vinegar and baking soda to produce a gas. With the addition of a bit of liquid soap, the gas becomes trapped in measurable bubbles.

In this playful, goopy activity, learners mix two liquids to create a solid (that sometimes acts like a liquid ), using basic household materials such as borax and glue.
