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 explore why the sky is blue. Learners model the scattering of light by the atmosphere, which creates the blue sky and red sunset, using a flashlight and clear glue sticks.

In this activity, learners explore clouds and how they form.

Many germs spread by our hands, and often times, people don't wash their hands well enough to get rid of germs.

In this activity/demo, learners investigate biobarcodes, a nanomedical technology that allows for massively parallel testing that can assist with disease diagnosis.

Learners match puzzle pieces to outlines of a DNA strand. The puzzle pieces represent the four chemicals making up DNA base pairs: adenine, thymine, guanine, and cytosine.

This fun and simple hands-on astronomy activity illustrates the path of light as it reflects off of mirrors and how this is used in telescopes.

In this optics activity, learners make a lens and explore how the eye manipulates the light that enters it.

In this activity (page 2 of PDF), learners play with a lens and a piece of paper to focus an image on the paper. Learners look at different things, and see how the lenses affect the image.

In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.

In this activity (last activity on the page), learners make a model of the eardrum (also called the "tympanic membrane") and see how sound travels through the air.

In this activity, learners interact with a 3-D model of a watershed to better understand the interconnectedness of terrestrial and aquatic environments.

Doctors often send a sample of blood to a lab, to make sure their patients are healthy.

In this activity, learners explore how eating unhealthy food can damage a heart and arteries.

Some bugs can walk on the surface of a lake, stream, river, pond or ocean.

In this activity, learners create a large film of soap and experiment with what can and cannot pass through it.

In "Chemistry Makes Scents," participants use their noses to distinguish between chemicals with very similar structures.
