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).

Some aquatic organisms live in open water, while some live in soil at the bottom of a body of water.

In this activity, learners walk the sides and interior angles of various polygons drawn on the playground. As they do so, learners practice rotating clockwise 180° and 360°.

In this activity, learners work in teams to study the observation skills essential to scientific research.

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

In this outdoor activity, learners review the parts of the synapse and their functions by playing a game.

In this activity, learners capture and observe planaria, which are worms that eat tiny pond critters.

In this activity, learners make pykrete by freezing a mixture of water and a material like cotton wool, grass, hair, shredded paper, wood chips, or sawdust.

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

Learners build a solar oven from a cardboard pizza box, aluminum foil and plastic. Learners can use their oven to cook S'mores or other food in the sun.

In this activity, learners will explore the ways natural materials can produce sounds. Appropriate for any age, learners can make individual music or create a symphony with others.

This is a comprehensive lesson plan on page 85 for a group cleanup trip to a local beach, lake or stream. Learners keep track of the types and amounts of trash picked up and analyze this information.

In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.

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.

In this activity, learners collect worms and then observe how they move.

In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

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

In this activity, learners will test soil content using their sample, some water and a container that seals.

In this activity, learners investigate parallax, a method used to measure distances to stars and planets in the solar system.

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.
