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.

Exploring Structures: DNA
Source Institutions
In this activity, learners create a necklace of wheat germ DNA. Learners add alcohol to wheat germ so that the DNA clumps together.

Bury Me Not!
Source Institutions
This activity (page 2 of the PDF under SciGirls Activity: Bogs) is a full inquiry investigation into decomposition.

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.

Push Me a Grape
Source Institutions
In this physics activity, learners experiment with the attractive and repulsive power of magnets.

Shimmering Lenses
Source Institutions
In this activity, learners use Jell-O to explore lenses. Learners cut Jell-O into convex and concave lens shapes and examine how light exits each lens in a darkened room.

Making Naked Eggs: Eggs Without Shells
Source Institutions
This is an activity about acid-base reactions using eggs and vinegar. Learners place eggs inside a container of vinegar and leave to soak overnight.

Mummy Magic
Source Institutions
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.

Finding the Carbon in Sugar
Source Institutions
In this activity about combustion and energy, learners observe a burning candle in a sealed jar and the burning of white sugar.

Cabbage Juice Indicator
Source Institutions
In this chemistry activity, learners make indicator solution from red cabbage. Then, learners test everyday foods and household substances using the cabbage juice indicator.

Hot & Cold
Source Institutions
In this activity, learners experiment with hydrogen peroxide, vinegar, yeast, and baking soda to produce hot and cold reactions. Use this activity to demonstrate exothermic and endothermic reactions.

Save Your Skin
Source Institutions
This is a fun activity about the power of the Sun and the importance of using sunscreen to protect your sensitive skin from its rays.

Fun with Flatware: Little Experiments to Try at the Dinner Table
Source Institutions
This is a series of three quick science activities to do with a spoon, knife, and fork. In the first two activities, learners use the flatware to explore optics, mirrors, reflection, and distortion.

Capturing Carbon Dioxide
Source Institutions
In this activity, learners investigate carbon sequestration by creating a carbonated beverage out of apple juice and dry ice.

Space Jell-O
Source Institutions
Albert Einstein proved that space bends around anything that has mass. This activity uses Jell-O's ability to bend around objects as a model for space bending around planets and stars.

Salt Painting
Source Institutions
In this art meets chemistry activity, early learners discover the almost magical absorbent properties of salt while creating ethereal watercolor paintings.

Swirling Milk
Source Institutions
In this chemistry activity, learners prepare two petri dishes, one filled with water and one filled with milk.

Moldy Jell-O
Source Institutions
In this laboratory activity, learners design an experiment to evaluate how environmental factors influence the growth of molds.
