In this three-part activity, learners use food to determine the effects of wind, sandblasting and water on regolith (dust) formation and deposition on Earth.

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

In this outdoor beach activity, learners use a variety of "beaks" (such as trowels, spoons or sticks) to hunt for organisms that shore birds might eat.

In this outdoor activity, learners investigate the relationship between the slope of a trail and soil erosion.

In this activity, learners take an indoor nature walk and discover various objects that have been brought in from the outdoor environment.

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.

In this outdoor activity, learners simulate an oil spill using popcorn (both oil and popcorn float on water), and estimate the spill's impact on the environment.

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

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

In this outdoor activity, learners plan a simple foot path and create an environmental impact study of the natural area where the path would be.

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 activity, learners explore the physics of impact craters from their own backyard using mud. Learners are encouraged to match features of real impact craters to their models.

In this kinesthetic activity that demonstrates pressure, learners act as air molecules in a "container" as defined by a rope.

In this hands-on and feet-on excursion, learners take a science walk to visualize the planet's immense size and numerous structures, without the usual scale and ratio dimensions found in most textbook

In this environmental science activity (page 3 of the PDF), leaners will identify and explain the causes of erosion.

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

In this activity (on pages 6-11), learners work as a team to investigate how impact craters on Earth, the Moon or other planets take shape and what patterns they make.

In this activity, learners model the flow of energy from the sun as it enters a photovoltaic cell, moves along a wire and powers a load.

In this activity (on pages 30-36), learners simulate a dig for ancient pollen, to experience how paleobotanists study fossilized pollen in rocks to learn about early geological and climatological even

In this three part activity, learners explore and experiment with shadows to learn about the Sun's relative motion in the sky.
