Intended for use after viewing the Science on a Sphere film "Water Falls," this lesson deepens student's understanding of global precipitation measurement. Students will explore NASA satellite data gathered during Hurricane Sandy to learn how that... (View More)

This is an activity about color. Participants will use scientific practices to investigate answers to questions involving the color of the sky, sunsets, the Sun, and oceans. This activity requires use of a clear acrylic or glass container to hold... (View More)

Audience: Informal education

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)

This model demonstrates convection currents and uses water, food coloring, a cup of very hot water and a votive candle as heat sources. Movie clips of demonstration setup and convection in action are provided. This activity is supported by a... (View More)

In this laboratory activity, students observe what happens when a fluid of one density is placed in a fluid of a different density. The fluids are salt water and fresh water, cold water and warm water. They generalize their results to describe what... (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)

In this laboratory investigation, student teams discover that the ocean's capacity to dissolve carbon dioxide depends on its temperature, and consider the effect of a warming ocean on CO² absorption. The activity requires Bromothymol blue indicator... (View More)

In this hands-on activity, students will test one aspect of a theory that reduction in the polar caps will speed global warming. They simulate a polar region with pans of water, one painted white to represent a glacier, and one painted black or blue... (View More)

In this activity, students Identify differences between photography and satellite imagery, and identify the features in true color and false color images. A worksheet, data sheet, answer key, and Web links are included. This is Lesson 5 in the unit... (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)
