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

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

In this lesson that includes hands-on activities and demonstrations, learners discover that it is the tilt of the Earth's axis (not its proximity to the sun) that causes the seasons.

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 seismic simulation, learners play a "who-dunnit" game to explore earthquakes.

In this online activity, learners build their own system of heavenly bodies and watch the gravitational ballet.

In this online activity, learners can test their skills at finding constellations in the northern hemisphere's night sky.

In this online activity, learners see simulations of how processes shape the Earth, and see estimates of how long these processes take.

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

In this online Flash game, learners take to the skies in a hot air balloon and are challenged to beat other balloonists' times to the finish line without crashing.

In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.

In this activity (on page 7), learners explore the meaning of a "carbon sink." Using simple props, learners and/or an educator demonstrate how plants act as carbon sinks and how greenhouse gases cause

This online simulation game explores the different consequences of water levels on the Columbia River in the Pacific Northwest.

In this activity, learners sample a star field to estimate the number of stars in the universe.

In this activity, learners conduct an experiment by heating an aluminum can filled with water to investigate air pressure.

In this game, learners walk through an imaginary Carbon Cycle and explore the ways in which carbon is stored in reservoirs and the processes that transport the carbon atom from one location to another

In this online activity, learners discover how random variation influences biological evolution.
