Students compare soils sampled from different environments and describe their color, texture, and composition. Samples of different soils are mixed with water in small vials, and water soil profiles are compared for difference in particle size and... (View More)

This activity introduces learners to the visible portion of electromagnetic spectrum. A visible spectrum is projected in the classroom using a diffraction grating and learners reproduce it using colored pencils. Filters are also used to block... (View More)

In this activity, students build an obstacle course for a flashlight beam using file cards, hole punch, clay, and observe that light travels in a straight line and demonstrate the concept of light extinction. The resource is part of the teacher's... (View More)

In this activity, students examine everyday objects with a flashlight and determine if they are transparent, translucent, or opaque. Common household materials such as wax paper, plastic wrap, aluminum foil, tissue, and food coloring are required.... (View More)

In this activity, learners will explore the properties of color filters and filter bandpass by observing light sources using diffraction grating and color filters and create a graph of percent transmission versus wavelength to characterize the... (View More)

In this kinesthetic game, student learn about light reflection. Teams line up with a series of mirrors and race to as they transfer a beam of light from one mirror to another as quickly as they can. A flashlight and 4 or 5 handheld mirrors are... (View More)
