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 make scale models of the Sun and Earth out of paper mache.

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 set of outdoor games, learners increase their awareness of the outdoor environment by going on a scavenger hunt and an out-of-place hunt.

In some parts of the world, lakes freeze during winter. In this activity learners will explore water’s unique properties of freezing and melting, and how these relate to density and temperature.

In this activity, learners build their own magnetometer using an empty soda bottle, magnets, laser pointer, and household objects.

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

In this outdoor activity/field trip, learners explore an aquatic site such as a pond, lake, stream, river or seashore to find and investigate plants and animals that live in water.
