This fun and simple hands-on astronomy activity demonstrates the shadow of the Earth as it rises as a dark blue shadow above the eastern horizon.

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.

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

Learners build 3D representations of constellations, which show not just the position of the stars as seen from Earth but also their relative distance from Earth.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

In this activity, learners build a simple solar oven out of household materials to melt chocolate and marshmallow between graham crackers--known as s'mores.

This activity (located on page 3 of the PDF under GPS: Temperate Rain Forest Activity) is a full inquiry investigation into biodiversity of a given habitat.

In this activity, learners construct hail-proof houses using recycled materials to discuss storm readiness and safety.

In this two-part lesson, learners discover how large bodies of water can serve as a heat source or sink at different times and how proximity to water moderates climate along the coast.

In this activity, learners examine ways that Native Americans of the Southwest express their relationship with nature through art.

In this activity (on page 1 of the PDF under SciGirls Activity: Earthquakes), learners will use a magnifier to carefully examine samples of sand from different locations.

In this water activity, learners build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.

Learners build models to learn about the special cells and structures that plants use to move water from their roots up through the stems and leaves.

In this activity, pairs of learners will create two make-believe dig sites by burying chicken bones in plaster of Paris--a powder that hardens when wet.

In this activity, learners use a compass, powerful magnet, and copper magnet wire to build a special generator known as a dynamo.

In this activity, groups of learners work together to create edible models of chemicals involved in autotrophic nutrition.

In this activity (located on page 3 of the PDF), learners investigate the way water moves and how we can control and direct water.

In this quick activity (located on page 2 of the PDF under GPS Wetlands Activity), learners will model how wetlands act as natural filters for the environment.
