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

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.

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, learners observe what happens when yeast cells are provided with a source of food (sugar). Red cabbage "juice" will serve as an indicator for the presence of carbon dioxide.

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

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.

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

This lesson gives full instructions for making cabbage juice indicator, a procedure sheet for learners to record observations as they use the indicator to test materials, and extension activities to d

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 activity on page 7 of the PDF (Chemistry—It’s Elemental), learners use iodine to identify foods that contain starch.

In this activity on page 8 of the PDF (Behind the Scenes with Chemistry), learners make three of Harry Potter's essential school supplies: quills, ink, and color-changing paper.

In this activity, learners use detergent solution to compare two solutions containing vinegar and cream of tartar.
