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 activity, learners perform an experiment to find out what determines a flower's color.

In this activity, learners will develop a method to test five similar-looking powders (baking soda, baking powder, cream of tartar, detergent, and cornstarch) with four test liquids (water, vinegar, i

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 chemistry activity (on page 2 of the PDF), learners corrode a penny in a cup with vinegar, salt water, and a source of iron (nails, paper clips, or twist ties).

In this activity, learners explore acids and bases by preparing six solutions that combine vinegar and ammonia, ranging from acid (all vinegar) to base (all ammonia).

In this Spanish-language chemistry activity, learners use simple materials to explore how fire extinguishers work to put out fires.

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

In this activity, learners transform everyday milk into small plastic figurines and jewelry. Use this activity to introduce learners to monomers and polymers.
