In this activity, student teams explore the connections between parts of the Earth system by examining a time series of environmental data maps. Each student teams examines images for two variables and determines if there is a direct or inversely... (View More)

In this activity, students analyze regions of sea ice using data and ImageJ software. They measure ice mass and calculate effective albedo, and plot changes in solar energy and water/ice cover percentages. This is part 4 of a four-part activity on... (View More)

In this activity, student teams explore connections between parts of the Earth system, by examining a time series of environmental data maps. Each team examines a single variable displayed on a global data map, and identify the unit of measure, the... (View More)

These two posters represent visual data collected from satellites, ground based observations, and model predictions representing solar energy, average temperature, cloud cover, precipitation, soil moisture and vegetation over 12 month periods in... (View More)

This article describes an approach designed to decrease math anxiety and teach students about the use of mathematical symbols simplifying radicals. A deck of cards is used in a demonstration, and a problem set using real life examples to master the... (View More)

This activity is designed to help building student understanding of how scientific theories can change over time. Science theories change in the face of new evidence. However, when new explanatory frameworks, or theories, are proposed to explain... (View More)

This is a lesson about solar system exploration. Learners will understand that combining information gathered by a variety of robots gives us a more comprehensive understanding of our solar system. Learners will explore a planet made up of a... (View More)

In this hands-on activity, students create a model soil profile in a two-liter beverage bottle, time the movement of water through different soils and observe the amount of water held in these soils. They observe the filtering ability of soils by... (View More)

Learners will compare satellite images of Mars and Earth to look for similar features. Then they brainstorm a list of forces or events that could have caused some of these features to form on Mars. This is activity 3 of 9 in Mars and Earth: Science... (View More)

In this activity, students produce a land cover map of a 15 km x 15 km GLOBE study site from hard copies of Landsat satellite images. Students place clear transparencies over the Landsat TM images and use markers to outline and classify areas of... (View More)
