In this activity, learners test what happens when they put baking power on different frozen liquids.

Learners observe a tank of water containing cans of diet and regular sodas. The diet sodas float and the regular sodas sink. All the cans contain the same amount of liquid and the same amount of air.

In this activity, learners will use simple materials to explore centripetal force and variables by swinging a cup of water without having the water spill out.

In this activity, learners explore the concepts of density and basic chemical reactions as they create a homemade lava lamp effect using water, oil, food coloring, and Alka-Seltzer tablets.

Learners investigate an iron-fortified cereal by stirring it with a strong magnet. They discover that metallic iron is present in some cereals.

In this activity, learners create their own experiment and test which of 4 mixtures of household chemicals turn pennies green over 5 days.

In this quick and simple activity, learners explore how the distribution of the mass of an object determines the position of its center of gravity, its angular momentum, and your ability to balance it

In this activity, learners use a tuning fork to explore how the Doppler effect works.

In this matching activity (3rd activity on the page), learners use their sense of smell to match pairs of opaque containers filled with various smelly items like orange peel, roses, or moth balls.

In this chemistry demonstration, learners investigate the rule "likes dissolve likes" by combining three, immiscible liquids to create a colorful density column.

In this activity, learners will create their very own constellation.

In this simple activity (on page 7 of the PDF), learners use water and liquid dish detergent to see which one removes lipstick better from an index card.

Learners roll their fingerpads in ink pads, and then press their fingerprints onto balloons. Learners inflate the balloons to produce enlarged versions of their fingerprints.

In this activity, learners discover how sweating makes us feel cooler. Learners put on one damp sock and one dry sock and sit in front of a fan.

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

Learners mix liquid water with solid cornstarch. They investigate the slime produced, which has properties of both a solid and a liquid.

Learners discover that their breath contains carbon dioxide, one of the pollutants found in car exhaust.

In this activity, learners create a large film of soap and experiment with what can and cannot pass through it.

In this activity, learners use water, oil, and food coloring to observe a chemical reaction that creates a shower of colors inside of a glass.

In this hands-on activity, learners explore static electricity through the use of common household products. They also explore the connection between static electricity and cold weather.
