Fat is a very important component in our diet. It's the most efficient source of energy in our bodies, and plays an important role in the flavor of foods.

In this activity, learners develop an understanding of cylinders and volume as they compare two sizes of popcorn buckets.

In this activity, learners explore the different salinities of various sources of water by taste-testing.

In this math activity, learners create their own units of measurement by making noodle rulers. Learners practice estimating and measuring objects using the noodle rulers .

In this quick activity (page 1 of PDF under SciGirls Activity: Exercise and Memory), learners will investigate what happens to bubble gum when it is chewed for 5-10 minutes.

In this activity/demo, learners discover how liquid nitrogen cools a creamy mixture at such a rapid rate that it precipitates super fine grained (nano) ice cream.

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.

In this lab exercise, learners explore diffusion, cell membranes and particle size using beets and three alcohols.

Learners place an M&M candy in water and observe what happens. The sugar-and-color coating dissolves and spreads out in a circular pattern around the M&M.

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 activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.

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.

In this activity, learners explore fractions as they help gators share pies.

In this activity, learners follow clues to find five puzzle pieces, then assemble them. This activity works well with a whole group, individuals, or families.

Through this nutrition activity (page 5 of the PDF), learners will understand—and probably be surprised by—how big serving sizes of various foods should be.

In this activity, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.

In this interactive and informative group activity, learners use packages of M&M's to illustrate the difference between weather and climate.

In this Cyberchase activity, have fun measuring volumes and enjoy a delicious shake.

En esta tira cómica, Mateo y Cientina emplean su conocimiento de la química y las medidas para esta actividad deliciosa - ¡hacer helado!

In this chemistry activity, learners use the lowered freezing point of water to chill another mixture (ice cream) to the solid state.
