This is a lesson about visual spectra. Learners will explore different ways of displaying visual spectra, including colored "barcode" spectra, like those produced by a diffraction grating, and line plots displaying intensity versus color, or... (View More)

This is an activity about the Doppler effect. Learners begin by simulating the noise made by a passing siren. After learning that the change in pitch results from movement, they investigate the definition of frequency, calculate change in frequency,... (View More)

This resource describes the physics behind the formation of clouds, and provides a demonstration of those principles using a beaker, ice, a match, hot water, and a laser pointer. This resource is from PUMAS - Practical Uses of Math and Science - a... (View More)

This is an activity about the electromagnetic spectrum and how light is split into its component frequencies or colors. Using a diffraction grating, learners will observe four different light sources and sketch their spectra. This activity requires... (View More)

This experimental activity is designed to develop a basic understanding of the interrelationship between temperature and pressure and the structure of a device made to examine this relationship. Resources needed to conduct this activity include two... (View More)

This experimental activity is designed to develop a basic understanding of the relationship between temperature and pressure and that a barometer can be constructed to detect this relationship. Resources needed to build a simple barometer include a... (View More)

This is a lesson to demonstrate magnetic field lines in 2- and 3-dimensions. In the first activity, learners sprinkle iron filings over a magnet underneath a paper and record their observations. The second activity involves building a 3-D magnetic... (View More)

Audience: Middle school
Materials Cost: $1 - $5 per group of students

This is a summative activity about magnets. Learners will observe a demonstration of the action of a magnet on a test tube of iron filings, answer questions, and, using the concepts learned in previous activities, write an essay about their... (View More)

This is lesson to begin learners' thinking about magnetic influence. Learners will watch a classroom demonstration about the effect of magnets on iron filings and then complete a journal assignment to record their reactions and thoughts. This is the... (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)
