Learners add drops of four liquids (water, alcohol, salt water, and detergent solution) to different surfaces and observe the liquids' behavior.

In this activity on page 3 of the PDF, learners create a collage by using vinegar to transfer color pictures from a newspaper onto a piece of white paper.

In this activity (on pages 4-5), learners make fake snow by adding water to the super-absorbant chemical from diapers, sodium polyacrylate.

In this activity, learners make their own "tornado" using two soda bottles and water.

In this activity learners compare the bounciness of warm and cold racquetballs to see if temperature makes a difference in how well they bounce.

In this activity on page 9 of the PDF, learners make their own paint using chalk as a pigment and glue and water as binders. This activity introduces learners to special mixtures called suspensions.

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 heat and cool carbonated water to find out whether temperature has an effect on how fast the dissolved gas leaves carbonated water.

In this activity (on page 8), learners model how marble statues and buildings are affected by acid rain.

In this activity, learners add objects and substances to carbonated water to discover that added objects increase the rate at which dissolved gas comes out of solution.

In this activity on page 4 of the PDF (Water in Our World), learners conduct some quick and easy tests to determine the differences between water and other liquids that look very similar to water.

In this activity on page 15 of the PDF, discover how materials and physical forces behave differently at the nanoscale.

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.

What causes frost to form on the outside of a cold container? In this activity, learners discover that liquid water can change states and freeze to become ice.

In this activity, learners separate materials based on their special properties to mimic the way recyclables are sorted at recycling centers.

In this activity, learners explore the relationship between cooling water vapor and condensation. Learners investigate condensation forming on the outside of a cold cup.

In this activity on page 6 of the PDF (Get Cooking With Chemistry), learners investigate yeast. Learners prepare an experiment to observe what yeast cells like to eat.

In this introductory activity, learners discover that sugar and food coloring dissolve in water but neither dissolves in oil.

In this activity, learners apply a dissolving test to known crystals to identify the unknown. Since the unknown is chemically the same as one of the known crystals, it should dissolve similarly.

In this activity on page 8 of the PDF, learners make a slimy substance very similar to mucus, and sprinkle it with glitter to imitate the way that allergens are trapped.
