In this crime science activity (on page 2 of the PDF), learners will explore the uniqueness of fingerprints. The will learn components of fingerprints as well as why fingerprints are left behind.

In this activity, learners make models representing bones on Earth and bones that have been in space. They discover what happens to bones without proper exercise and nutrition.

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

In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

In this activity, learners explore how to stay fit the fun way. Learners participate in three physical activities.

In this activity about engineering, nutrition, and physical activity, learners design and build a healthy bone model of a space explorer which is strong enough to withstand increasing amounts of weigh

This exercise is designed to teach young learners the different parts of a plant (root, stems, leaves, flowers, fruit, and seeds), the basic functions of each part, and to show that tiny microscopic o

In this invention challenge activity, learners create an indoor game for one or two people that gets you moving.

In this invention challenge activity, learners see how many objects they can grab with a homemade "bionic" arm.

This activity (page 3 of the PDF under SciGirls Activity: Dinosaurs) is a full inquiry investigation into fossil hunting and identification.

In this activity, learners test the rate of ripening fruit and vegetables and use a chemical to inhibit the ripening process.

In this activity, learners will train to increase bone strength and to improve heart and other muscle endurance by performing jump training with a rope, both while stationary and moving.

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.

In this activity (on pages 26-33), learners play parasitologists, solving several "mysteries" about people who got sick from various parasites. In teams of four, each member solves one mystery.

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

In this activity, learners will train to improve lung, heart, and other muscle endurance as they walk a progressive, measured distance.

This quiz lets you estimate your annual radiation exposure.

In this activity, learners will perform various investigations to understand the vestibular-ocular reflex and learn about the importance of visual cues in maintaining balance.

In this activity, learners examine antibodies and antibody recognition using a model.

In this activity, learners train to increase muscular strength and improve upper and lower body coordination by performing the “bear crawl” and the "crab walk.” Learners perform the exercises over tim
