Powder Particulars
Source Institutions
In this introductory activity and demonstration, learners are introduced to the concept that different substances react chemically in characteristic ways.

Spaghetti Strength
Source Institutions
In this activity on page 7 of the PDF, learners explore how engineers characterize building materials.

Sweet Measurements
Source Institutions
In this activity on page 3 of the PDF, learners investigate how much sugar is in a soda. Learners use sugar cubes to measure and calculate the amount of sugar in a bottle of soda.

A Feast for Yeast
Source Institutions
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.

Veggies with Vigor
Source Institutions
In this activity, learners try to revive wilted celery. Learners discover that plants wilt when their cells lose water through evaporation. Use this activity to introduce capillary action.

Dissolving Different Liquids in Water
Source Institutions
In this activity, learners add different liquids to water and apply their working definition of “dissolving” to their observations.

Avi's Sensational Salt Dough
Source Institutions
In this activity on page 5 of the PDF, learners mimic the process for making bricks. Learners shape and bake creations from a dough that is made from flour, salt, and water.

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.

Temperature Affects the Solubility of Gases
Source Institutions
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.

Iodine Investigators!
Source Institutions
In this activity on page 7 of the PDF (Chemistry—It’s Elemental), learners use iodine to identify foods that contain starch.

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.

Testing Vitamin C: Chemistry's Clear Solution
Source Institutions
In this activity on page 8 of the PDF, learners investigate vitamin C. Learners conduct a chemistry experiment to determine if Tang drink mix or orange juice contains more vitamin C.

Dissolving a Substance in Different Liquids
Source Institutions
In this activity, learners make colored sugar and add it to water, alcohol, and oil to discover some interesting differences in dissolving.

Special Effects Using Household Chemicals
Source Institutions
In this activity on page 4 of the PDF (Behind the Scenes with Chemistry), learners make some special effects, including snow and breaking glass, with supplies found in the home.

Milli's Insulation Investigation
Source Institutions
In this activity on page 2 of the PDF, learners test different materials to find out which is the best insulator.

Homework, Hogwarts Style
Source Institutions
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.

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.

Temperature Affects Dissolving
Source Institutions
Learners design their own experiment to compare how well cocoa mix dissolves in cold and hot water. They will see that cocoa mix dissolves much better in hot water. Adult supervision recommended.

Apples with Appeal
Source Institutions
In this activity, learners investigate why apples turn brown. Learners discover that lemon juice interferes with the reaction that causes the browning.

Changing the Density of an Object: Adding Material
Source Institutions
Learners see that a can of regular cola sinks while a can of diet cola floats. As a demonstration, bubble wrap is taped to the can of regular cola to make it float.
