In this activity (on page 1 of the PDF), learners make a "mini-globe" to investigate the causes of day and night on our planet.

This is an activity (located on page 131 of the PDF) related to sleep and circadian rhythms as well as space travel.

In this activity, learners investigate the formation of craters. Learners will examine how the size, angle and speed of a meteorite's impact affects the properties of craters.

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

In this activity (on pages 36-39), learners make a model of a watershed out of paper, then run water down the mountain to simulate how rainfall and pollution affect watersheds.

In this online activity, learners adjust mountain snowfall and temperature to see how glaciers grow and shrink. They will use scientific tools to measure thickness, velocity and glacial budget.

In this activity, learners discover how to determine the distance to a lightning strike or nearby thunderstorm.

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

This fun and simple hands-on astronomy activity lets learners create 3D models of the Earth, Moon and Sun to demonstrate solar and lunar eclipses.

This is an activity (located on page 3 of the PDF under Water Clean-up Activity) about the use of reduction agents to decontaminate ground water.

In this activity, learners discuss the different salinities of oceans, rivers and estuaries.

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 online Flash game, learners will explore a coral reef using an underwater remotely operated vehicle (ROV).

In this online Flash game, learners will captain a sailing challenge, adjusting boat direction and sails, seeking the way to take greatest advantage of varying wind speeds and directions to catch the

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 activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

Through doing these hands-on activities, learners explore the environmental consequences associated with fossil fuel usage.

In this creative roleplay activity, learners will explore the various processes of the water cycle using movement, sound, and props to aid in comprehension.

Ancient trash tells archaeologists a lot about the past. In this activity, learners take a close look inside their trash can and think about the clues it offers about their lives.

In this activity, learners explore the engineering behind seismographs and how technology has improved accurate recording of earthquakes.
