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 fun hands-on activity, learners whip up a batch of cyber-dough (play dough) using math for measurements.

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 activity learners observe mold growth on different types of bread by measuring and recording the growth rate.

In this nutrition activity, learners explore food labels and consider the nutritional value of foods. Learners also explore units of measurement commonly used on food labels.

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

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 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 simulation, learners use M&M™ candy to explore radioactive isotope decay.

In this activity, learners build edible models of Jupiter and Earth to compare their sizes and illustrate the planets' internal layers.

In this math activity, learners guess which cereals contain the most sugar. Learners use the nutrition labels on the cereal boxes to find the cereal with the least amount of sugar.

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

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

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

In this activity, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.
