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 problem set, students calculate precisely how much carbon dioxide is in a gallon of gasoline. A student worksheet provides step-by-step instructions as students calculate the production of carbon dioxide. The investigation is supported the... (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)

This is an activity about bar magnets and their invisible magnetic fields. Learners will experiment with magnets and a compass to detect and draw magnetic fields. This is Activity 1 of a larger resource, entitled Exploring the Sun. The NASA... (View More)

The front of this poster is a cartoon profile of the atmosphere, showing the "good and bad" roles of ozone in the stratosphere, high troposphere, mid-troposphere, and surface. On the back is an article for students, beginning with an explanation of... (View More)
