In this activity (page 7 of the PDF), learners will investigate the contents of owl pellets. Learners will discover how owls digest their food as well as the kind of animals they eat.

In this activity, learners perform 20 arm curls with cans that simulate the weight of beans on Earth versus the weights of the same number of beans on the Moon and in space.

This activity (page 2 of the PDF under SciGirls Activity: Double Dutch) is a full inquiry investigation into whether hearing or seeing has a bigger effect on jump rope performance.

In this activity, learners examine how colored lenses act like filters and absorb all colors of light except for the color of the lenses.

In this activity, learners find out why some mineral sunblock rubs in clear. Learners compare nano and non-nano sunblocks and discover how particle size affects visibility.

In this kinesthetic activity, learners move pom-pom "ions" across a membrane to simulate how an action potential is propagated along an axon.

In this health activity (page 5 of the PDF), learners will explore a unique connection betweeen the bones of the body.

In this activity about human anatomy (page 20 of PDF), learners investigate the structure of muscles by comparing yarn and cooked meat.

In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

In this activity, learners investigate the touch sensory system and discover how to plan and carry out their own experiments.

In this activity about light and refraction, learners discover how a lens creates an image that hangs in midair.

In this activity, learners will explore the foods that are in their kitchen and what sugars are inside of them. Explore nutrition and food labels to better understand the foods you eat.

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 exercise and nutrition activity, learners will explore how food is the fuel that powers them. They will create a chart to figure out how many calories they burn during recess.

In this optics activity, learners examine how polarized light can reveal stress patterns in clear plastic.

Cool off in the heat with this project! Learners use simple materials to build a fan that runs on a motor.

In this activity, learners will conduct an experiment to discover methods of reventing foot mold growth on food.

In this activity, learners explore cooked chicken wings and identify the various parts including: bones (radius, ulna, humerus, shoulder joint, elbow joint), tendons, and cartilage.

In this activity, learners create slime to model mucus and examine how it collects simulated particles. Mucus keeps particles from the environment out of our lungs when we breathe.

Learners mark their traits for tongue rolling, PTC tasting (a harmless, bitter chemical), and earlobe attachment on tree leaf cut-outs.
