In this activity (4th activity on the page), learners use their sense of smell to rate and arrange containers filled with different dilutions of a scent (like cologne or fruit juice) in order from wea

In this online activity, learners experience the thrill of pickle making, and explore how a cucumber becomes a pickle.

In this optics activity, learners use a shoebox, colored cellophane and sunlight to "change" the colors of gumballs. Learners will be surprised when the green and blue gumballs appear black!

In this activity on page 7 of the PDF, learners follow a recipe to make a dough similar to the clay artists use to make sculptures.

In this activity, learners examine baking powder, a combination of three powders: baking soda, cream of tartar, and cornstarch.

In this activity, learners add food coloring to hot and cold water to see whether heating or cooling affects the speed of water molecules.

In this physics demonstration, learners are challenged to break a raw egg just by squeezing it. Learners will be shocked by their inability to complete the deceivingly simple challenge.

In this chemistry demonstration, learners investigate the factors that increase the rate of dissolution for a solid.

In this activity on page 9 of the PDF, learners test how flavoring extracts move through the walls of a balloon.

In this activity, learners create a "mini sky" in a glass of water in a dark room.

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.

In this activity, high voltage is applied across a pickle to emit a yellow glow. This activity should only be conducted by skilled adults and is best suited as a demonstration.

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.

In this optics activity, learners explore how they can make gelatin stop light, but not stop them from seeing fruit suspended within.

In this activity, learners mix up a bubbly brew and examine density. Learners explore how they can make different materials fall and rise in water using oil, water, and salt.

In this activity, learners investigate the movement of water into and out of a polymer. Learners test the diffusion of water through gummy bears, which are made of sugar and gelatin (a polymer).

In this activity on page 2 of the PDF (Get Cooking With Chemistry), learners conduct chemical tests on certain powders used in cooking.

Learners use their knowledge of color changes with red cabbage indicator to neutralize an acidic solution with a base and then neutralize a basic solution with an acid.

In this activity, learners conduct a series of hands-on experiments that demonstrate how the working of plants' veins, known as capillary action, enables water to travel throughout the length of a pla

In this quick activity (on page 2 of the PDF under GPS: Body Electricity Activity), learners will observe how dry breakfast cereal appears to dance when it gets close to a balloon charged with static
