In this activity, learners conduct a controlled experiment to examine how temperature will affect the height of a soda geyser.

In this tasty activity, learners make their own ice cream any day of the year in an exploration of heat and cold. Highlights include freezing and melting and the transition from liquid to solid.

In this dynamic activity, learners build a catapult that launches projectiles, such as marshmallows.

In this activity, learners use the Sun's energy to cook marshmallows. Learners construct the solar oven out of simple everyday materials.

Learners carefully pour vegetable oil, water, and corn syrup in any order into a cup and discover that regardless of the order they are poured, the liquids arrange themselves in layers the same way.

In this activity, Frankenstein's lab is running out of electricity! Learners use fruit to help Igor find a temporary source of energy to turn on a light.

In this activity, learners investigate the process of osmosis by adding salt to a sealed bag of raw carrots and comparing it to a control.

In this activity, learners explore engineering package designs that meet the needs of safely shipping a product.

In this activity, learners conduct a controlled experiment to examine which brand of soda makes the best (highest) soda geyser.

Create a chemical reaction that makes cheese! This hands-on activity demonstrates that molecules and atoms are tiny particles that make up everything around us.

In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.

In this design challenge, learners will use microbes to design and grow a custom biomaterial at home and make something creative with it.

In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.

This is an activity (on page 2 of the PDF under Surface Area Activity) about surface area to volume ratio.

In this activity related to rotational inertia (page 1 of the PDF under SciGirls Activity: Microgravity), learners will use a bit of scientific experimenting to test if open-faced peanut butter sandwi

In this hands-on experiment, kids use chemistry to explore whether acids or bases are better at restoring a penny’s shine.

In this activity, learners compare and contrast their own skin (including the area covered) with that of an orange.

DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique. This activity allows you to see long, stringy strands of DNA extracted from wheat germ.

In this math lesson, learners are introduced to proportional reasoning through modeling, sharing, and questioning techniques.
