In this activity, learners observe fly behavior and then build a flytrap.

In this activity, learners will take a step back and learn the history of the land they live on, and the people who used to live on it.

Learners experiment with a commercial photo-sensitive paper (Sunprint® or NaturePrint® paper). They place opaque and clear objects on the paper and expose it to bright light, observing the results.

In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

In this activity, learners explore the concept of valve operation and how engineers have adapted valves for use in mechanical heart valve design.

This fun hands-on astronomy activity uses a variety of simple props to help learners understand why they see what they see in a telescope.

In this activity, learners observe hard parts of sea creatures (shells, molts, etc.) to better understand marine environments.

Glare from the sun and ripples from the wind can make it hard to see what's below the surface of a body of water.

In this field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.

In this activity, learners survey living organisms near where they live or go to school, and create a local field guide.

In this laboratory experiment, learners explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation.
