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 design challenge, learners will engineer a structure and see if it can survive an earthquake they create.

In this activity, learners discover how the extent of various wind speeds changes in each of the four quadrants around a hurricane.

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

In this activity, learners explore how the area of Arctic sea ice has changed over recent years. First, learners graph the area of Arctic sea ice over time from 1979 to 2007.

In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.

In this kinesthetic activity, learners will play a game with a ball to demonstrate the Coriolis force, which partly explains why hurricanes in the Northern Hemisphere rotate counterclockwise.

In this activity, learners make their own "tornado" using two soda bottles and water.

In this activity (located on pages 9-14 of PDF), learners visit a cemetery to examine the distinguishing characteristics of rock weathering.

In this quick activity, learners use a toaster to investigate the source for the Earth's wind. Learners hold a pinwheel above a toaster to discover that rising heat causes wind.

In this online interactive, learners use fossils to infer temperatures 55 million years ago, at the sites where the fossils were found.

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

This quiz lets you estimate your annual radiation exposure.

In this quick and easy activity and/or demonstration, learners illustrate the effect of the weight of air over our heads.

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.
