This is an activity about the size of the Sun. Learners will construct a pinhole camera and, using the projected image of the Sun, calculate its diameter. After calculating the diameter of the Sun, learners will create a classroom sized scale model... (View More)

In this problem set, learners will analyze a graph of the reflectivity of soil and two kinds of vegetation to understand how scientists use these measures to identify different materials. Answer key is provided. This is part of Earth Math: A Brief... (View More)

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... (View More)

This interactive, online activity provides a method for generating waves using a computer. Students can select the energy they want the waves to have, observe how the waves appear on the screen, and then measure the frequency and wavelength of the... (View More)

In this kinesthetic activity, students learn how photons may be transmitted, absorbed, or scattered. Materials required include a small ball, an overhead projector, 4 clear cups, different liquids (milk, water, black ink, grape juice), and a... (View More)

This resource uses an everyday example of walking a dog as a context where students can observe changes in shadows over the course of a day, and deduce that light travels and tends to maintain its direction of motion. The activity is from PUMAS -... (View More)
