Say Cheese!
Source Institutions
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.
Mystery Powders
Source Institutions
Learners are given mysterious white powders and have to determine their identity with chemical tests.
Universal Indicator Rainbow Trout
Source Institutions
In this activity on page 2 of the PDF, learners discover how color changes can help scientists distinguish between acids and bases.
Color Changes with Acids and Bases
Source Institutions
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.
Homemade Bath Fizzies
Source Institutions
In this activity, learners make their own bath bomb fizzies and experience what happens when they mix a base and an acid.
Change in Temperature: Endothermic Reaction
Source Institutions
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.
Neutralizing Acids and Bases
Source Institutions
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.
New Sense about Cents
Source Institutions
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.
pH Scale
Source Institutions
In this online interactive simulation, learners will test the pH of liquids like coffee, spit, and soap to determine whether each is acidic, basic, or neutral.
Reaction: Yes or No?
Source Institutions
In this activity, learners mix ingredients in a plastic bag, and then identify three characteristics of a chemical reaction: production of heat, color change, and production of a gas.
Edible Ink
Source Institutions
In this chemistry activity (page 6 of the PDF), learners observe a chemical change. Learners write and reveal a secret message using edible ink.
Finding Colors
Source Institutions
In this chemistry challenge, learners combine acids and bases in a universal indicator to create five different colors.
Pop Rockets
Source Institutions
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.
Breathing Blue
Source Institutions
In this activity, learners test exhaled breath for carbon dioxide and learn how to use an indicator as a simple way to measure pH.
Cheese: Behold the Power of Chemistry
Source Institutions
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.
Powder Particulars
Source Institutions
In this introductory activity and demonstration, learners are introduced to the concept that different substances react chemically in characteristic ways.
Como funciona un extintor
Source Institutions
In this Spanish-language chemistry activity, learners use simple materials to explore how fire extinguishers work to put out fires.
Comparing the Amount of Acid in Different Solutions
Source Institutions
In this activity, learners use detergent solution to compare two solutions containing vinegar and cream of tartar.
