This activity (located on page 3 of the PDF) is a full inquiry investigation into mapping the underground “plumbing” of geysers.

In this activity, learners will create their own lava lamps. Learners will explore density, effervescence and chemistry through this activity.

In this activity, learners model hot spot island formation, orientation and progression with condiments.

In this activity, learners make a flip book that shows the progression of two solar events on reversible sides of the flip book.

In this activity, learners will learn how igneous rock, metamorphic rock, and sedimentary rock are formed as part of the rock cycle and that the same forces that produce/change rocks also produce/chan

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 activity, learners discover if carbon dioxide has an effect on temperature.

Learners use beach profile data from a local beach or online data from Ocean City, Maryland to investigate coastal erosion and sediment transport.

In this interdisciplinary activity, learners create a Space Weather Action Center (SWAC) to monitor solar storms and develop real SWAC news reports.

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 use crayons to draw conclusions about rocks and the rock cycle.

In this activity, learners investigate the food, water, and space needs of common livestock animals.

In this quick activity (page 2 of PDF under GPS: Lava Flow Activity), learners will model how large depressions near the top of a volcano are formed by using an inflating and deflating balloon submerg

This activity gets learners looking at 6-sided shapes in nature, including the cells of a beehive, as well as other shapes.

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 explore the engineering behind seismographs and how technology has improved accurate recording of earthquakes.

In this activity, learners explore clouds and how they form.

In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

“Exploring Earth: Investigating Clouds” is a hands-on activity in which visitors create a cloud in a bottle and explore it with laser light.
