In this outdoor activity and observation game, learners hunt for a variety of textures, colors, odors and evidence of organisms in the activity site.

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 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 activity/game, learners use thermometers to simulate how lizards survive in habitats with extreme temperatures.

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.

This fun and simple hands-on astronomy activity lets learners make 3-dimensional models of the Earth and Moon.

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 use a simple 3D model to discover why the Moon has phases.

In this activity, learners make their own solar oven to bake s'mores and learn about how solar energy is absorbed on Earth.

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 meteorology activity, learners construct simple devices to measure the direction and speed of wind.

Through a series of simple body movements, learners gain insight into the relationship between time and astronomical motions of Earth (rotation about its axis, and orbit around the Sun), and also abou

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 small-group activity, learners assume the roles of pilots, air traffic controllers, and NASA scientists to solve five Air Traffic Control (ATC) problems.
