In this sensory activity, young learners explore chemical reactions by making their own play dough from home.

In this activity, learners build edible models of DNA, while learning basic DNA structure and the rules of base pairing.

Make your own mummy! Using a combination of salts, transform an apple into a mummy and discover how the Ancient Egyptians used drying as one step in the mummification process.

In this activity (on page 2 of PDF), learners mix oil and water. Then, they add soap and observe what changes! The activity demonstrates how oil and water don't mix, except when soap is added.

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

Learners place multiple M&M's in a plate of water to watch what happens as the candies dissolve.

In this activity, learners experiment with different variables in making hollandaise sauce to achieve the correct texture and consistency.

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

In this chemistry activity (page 3 of the PDF), learners will observe a chemical change, specifically what happens to iodine when it is applied to ripe and unripe apples.

In this activity, learners experiment with the density of ice, water, and oil. Learners will discover that the density of a liquid determines whether it will float above or sink below another liquid.

Learners place an M&M candy in water and observe what happens. The sugar-and-color coating dissolves and spreads out in a circular pattern around the M&M.

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 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 kinesthetic activity, learners move pom-pom "ions" across a membrane to simulate how an action potential is propagated along an axon.

In this chemistry activity, learners use spaghetti to explore density and chemical reactions.

In this activity, learners use marshmallows and gum drops to construct seven models of molecules. Learners classify (solid, liquid or gas) and draw diagrams of the molecules.

Learners observe a bottle containing water and oil. They are invited to pick up the bottle and mix the contents together.

In this hands-on activity (on page 2 of the PDF), learners experiment with lemon juice and paper to create a message that can only be revealed using chemistry.

In this chemistry meets cooking activity, learners compare the stability of egg white foams with various additives.

Does yeast breathe? Find out by watching how plastic bags filled with yeast, warm water and different amounts of sugar change over time.
