In this food science activity, learners explore digestion and proteins by observing the action of meat tenderizer on luncheon meat.

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

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

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 activity (located on pages 23-24 of the PDF), learners are introduced to structural engineering and encouraged to practice goal-oriented building.

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.

Learners use M&Ms® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air.

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.

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

In this (edible) activity, learners balance chemical equations using different kinds and colors of candy that represent different atoms. Learners will work in pairs and explore conservation of atoms.

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.

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

This is a classic exercise for visualizing the scale of the Solar System.
