This fun hands-on astronomy activity lets learners use star maps (included) to find constellations and to identify stars with extrasolar planets (Northern Hemisphere only, naked eye).

Millions of organisms can live in and around a body of water.

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

In this outdoor activity/field trip, learners investigate organisms that live along the ocean's rocky coast.

This fun and simple hands-on astronomy activity lets learners explore model planets (that they or an educator will create), using methods NASA scientists use to explore our Solar System.

In this activity, learners use a simple 3D model to discover why the Moon has phases.

In this craft activity, learners create a string of cut-out moons and stars.

In this two-part outdoor activity, learners conduct a population census of squirting clams on a beach or mudflat, and investigate the clams' natural history.

In this outdoor, beach activity, learners use tennis balls, water balloons and other simple devices to investigate the movement of waves and currents off a sandy beach.

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

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

This fun, nighttime hands-on astronomy activity lets learners explore how long it takes for light from different objects in the universe to reach Earth.

This is a classic exercise for visualizing the scale of the Solar System.

In this activity, learners make their own pinhole viewer in order to measure the size of the sun.

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

How do scientists measure how clear or murky water in a lake is? How does water clarity (clearness) affect what lives in the lake?

In this activity, learners make a small batch of biodiesel that will work in any diesel engine. Learners use an old juice bottle as a "reactor" vessel to chemically process vegetable oil into fuel.
