Learners will use an inexpensive, simple spectrophotometer to test how light at different visible wavelengths (blue, green, red) is transmitted, or absorbed, through four different colored water samples. Clear water is used as the “control,”... (View More)

This activity presents a digital interactive where students identify anthropogenic sources of carbon dioxide and their relative contribution to carbon enrichment of the atmosphere. Students then obtain a photograph pair of a scene in their... (View More)

In this demonstration activity, students make structural models of gas molecules using pipe cleaners and polystyrene balls and test their molecules for their resonant frequency. Students shake the models, count vibrations, and compare the resonance... (View More)

In this field activity, students document examine the role of a tree in its ecosystem and as part of the environment in a human community. Students measure the tree's dimensions, examine co-residing organisms, leaf litter, and soil, and research the... (View More)

This lesson applies the science and math of the rotation of a sphere to water and wind movements on Earth. Students are introduced to convection, the Trade Winds and the Coriolis Force. Using an online visualizer, students generate trajectories and... (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)

In this learning activity, students compare changes in insolation with changes in surface temperature in the polar regions using scientific visualizations of global data sets. Links to readings related to the shrinking ice cap and albedo are... (View More)

In this learning activity, students compare polar data from the Arctic and Antarctic, explore Earth’s albedo and its effect on arctic sea ice, and examine graphed data and scientific visualizations of remotely-sensed satellite data. Readings... (View More)

Students will explore time series plots and raw data to understand the role of sea surface temperature increases on arctic ice melt. This is part three of a four-part activity on polar science. The activity builds on the knowledge gained in Using... (View More)

This interactive website engages children in a story-based scenario that emphasizes concepts of remote sensing and how NASA scientists use satellite imagery to better understand the Earth's environmental changes. The story features a pigeon named... (View More)
