In this activity about physical stress (page 28 of PDF), learners discover that muscles and bones need to work to stay strong.

This is written as a display, but can easily be adapted to a hands-on activity. Learners observe and shake containers of shiny liquids.

In this activity about the human heart (on page 5 of the PDF), learners work in teams to simulate the volume of blood moved through the circulatory system by transferring liquid into--and through--a s

In this activity about heart health (on page 34 of the PDF), learners measure their own blood pressure using an electronic blood pressure monitor with a self-inflating cuff (included in cost of materi

In this activity, learners will measure their lung capacity by making their own spirometer. Learners will then explore factors that affect the amount of air the lungs can hold.

In this activity, learners investigate how geometry plays a role in perspective.

This is a fun activity about the power of the Sun and the importance of using sunscreen to protect your sensitive skin from its rays.

In this activity, learners examine photo images of Earth taken from space, and attempt to identify and explain some of our planet's geological features.

In this activity (page 5 of pdf), learners explore the relationships between the shape and structure of a shark's teeth and the food it eats, and then create their own shark tooth from clay.

In this activity, learners build a paper model of the spacecraft and photometer (telescope) used during NASA's Kepler Mission.

In this simple activity (on page 2 of the PDF), learners make a crystal garden using salt, water, and a brick.

In this activity, learners use a toaster to generate wind and compare the appliance's heat source to Jupiter's own hot interior. Learners discover that convection drives wind on Jupiter and on Earth.

Learners imagine they are paleontologists in Florida, where they find (remove from envelope) paper "fossils" of some unknown creature, only a few at a time.

In this activity, learners will create unique rockets. Each rocket will be powered by air as the learner will blow into a straw and watch their rocket fly.

In this physics activity, learners will investigate the strength of egg shells.

In this activity, learners trap a thin layer of air between two pieces of Plexiglas to produce rainbow-colored interference patterns.

In this environmental science activity (page 4 of the PDF), learners use vinegar and chalk to observe the effect of acid rain on various building materials and plant life.

In this activity, learners will create a home for animal friends in their backyard using recycled materials. Some material suggestions include: pine straw and twigs.

In this activity, teams of learners study magnetic fields at four separate stations: examining magnetic fields generated by everyday items, mapping out a magnetic field using a compass, creating model

Make a one-string "guitar" by stringing a cup with some fishing line. You amplify the plucking of the string by placing a piezo contact microphone and mini battery powered amplifier inside the cup.
