This demonstration shows that similar-appearing lights can be distinctly different, suggesting that the light emitted is generated in different ways. It requires some advance preparation/setup by the teacher and three recommended sources of orange light, that can be purchased at a hardware or department store. Includes extensions and additional background information on light generation in a section ... Full description.

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 of surfaces in the solar system. Materials required for the outdoor demonstration include a cement step, sand, laboratory thermometers, foam rubber, and ... Full description.

Comment on this resource
This lesson addresses the common student misconception that the Earth is closer to the Sun during the summer in the Northern Hemisphere. This lesson encourages students to voice this misconception at the beginning of the lesson and then attempts to correct it-first, by exploring the reason for it, and then by presenting an alternate explanation. Materials needed for the demonstration include a small ... Full description.

In this activity, students compute the strengths of the gravitational forces exerted on the Moon by the Sun and by the Earth, and demonstrate the actual shape of the Moon's orbit around the Sun. The lesson begins with students' assumptions about the motions of the Moon about the Earth and the Earth about the Sun, and then test their understanding using an experimental apparatus made from a cardboard ...

Atmospheric scientists use computer models to forecast the position of a moving volcanic cloud, and remote sensing can identify its components, including gases and aerosols. This resource provides ideas for classroom investigation of these topics, and directions for a demonstration of light scattering by aerosols. The lesson ideas are from PUMAS - Practical Uses of Math and Science - a collection ... Full description.
