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

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 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 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.

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

In this activity (on pages 12-15), learners make a crater model and test the effects of weather (rain) on its surface.

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

In this activity, learners will model the mechanical weathering and erosion of rocks in a stream or river.

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

In this activity, learners investigate soil erosion. Learners set up a simulation to observe how water can change the land and move nutrients from one place to another.

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

In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.

In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.

In this activity (page 1 of the PDF under SciGirls Activity: Dinosaurs), learners will model how paleontologists estimate the age of fossil discoveries by extracting “fossil” playing cards from newspa

In this three-part activity, learners explore how waves are formed and why some waves are bigger than others. First, learners observe waves of water in a pan generated by an electric fan.

In this quick activity, learners explore how blubber protects animals from the cold by making a "blubber mitt." Using cooking shortening, two zip-top sandwich bags, and duct tape, learners simulate bl
