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 on page 2 of the PDF, learners discover how color changes can help scientists distinguish between acids and bases.

In this activity, Frankenstein's lab is running out of electricity! Learners use fruit to help Igor find a temporary source of energy to turn on a light.

Learners mix a variety of substances with red cabbage juice. The juice changes color to indicate whether each substance is an acid or a base.

In this activity, learners make their own bath bomb fizzies and experience what happens when they mix a base and an acid.

Learners investigate signs of a chemical reaction when they mix vinegar and baking soda. In addition to a gas being produced, learners also notice the temperature decreases.

In this activity, learners will experiment with changing flower colors. Learners will investigate the effects of acids and bases on flower colors.

Learners use their knowledge of color changes with red cabbage indicator to neutralize an acidic solution with a base and then neutralize a basic solution with an acid.

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, learners test the pH of safe liquids available at home by creating a pH indicator from mashed blueberries.

Learners make their own acid-base indicator from red cabbage. They use this indicator to test substances around the house.

Electrolysis is the breakdown of water into hydrogen and oxygen. This Exploratorium activity allows learners to visualize the process with an acid-based indicator.

In this chemistry activity (page 6 of the PDF), learners observe a chemical change. Learners write and reveal a secret message using edible ink.

In this chemistry challenge, learners combine acids and bases in a universal indicator to create five different colors.

In this activity, learners make film canister rocket ships. A fin pattern is glued onto the outside of the canister, and fuel (water and half an antacid tablet) is mixed inside the canister.

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 chemistry activity, learners will test the pH of various foods and household substances using cabbage.

In this activity on page 7 of the PDF (Get Cooking With Chemistry), learners conduct an experiment to get an idea of how cheese is made.

In this introductory activity and demonstration, learners are introduced to the concept that different substances react chemically in characteristic ways.

In this experiment, learners test multiple food items to see if they are an acid or base using an indicator solution created with red cabbage.
