In this outdoor activity/field trip, learners catch and observe water striders to explore their movement and feeding behaviors.

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.

In this outdoor activity, learners visit the intertidal zone of a rocky coastal site well populated with marine organisms.

In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.

In this activity, learners model erosion using a clear shoebox and sand or soil.

In this activity, learners construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.

In this design-based lesson, learners study flood dynamics as they modify a riverbed with blockages or levees to simulate real-world scenarios.

This activity (on page 2 of the PDF under SciGirls Activity: Malformed Frogs) is a full inquiry investigation into using indicator species to assess the health of an environment.

In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.

In this activity, learners explore rocketry and the principals of space flight.

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.
