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 lesson bridging art and science, students build understanding of the terms translucent, opaque, and transparent, as they apply to cloud descriptions, and create a collage using materials matching these characteristics, as well as a... (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 are introduced to the concept of remote sensing. In the course of this experiment, students will investigate heat conduction on two surfaces and understand the application of these techniques to spacecraft investigations... (View More)

This activity, effective outdoors or indoors, demonstrates how insolation is affected by latitude by using a pair of thermometers, each taped to some cardboard, placed outside on a sunny day. A globe can also be used, outdoors or indoors. Students... (View More)

In this lesson, students are introduced to the electromagnetic spectrum. They observe a demonstration of the visible light spectrum created by a flashlight and a prism, complete an activity sheet where they identify the wavelength that is involved... (View More)

Students are introduced to classification through progressive activities. Initially, the teacher models the task by classifying buttons. Students then devise a classification scheme for paper clips. Subsequent activities use objects brought from... (View More)
