Curated OER
WAVES AND PHOTONS
Students examine the many types of electromagnetic waves, the concept of an EM wave, how James Clerk Maxwell proposed a slight modification of the equations of electricity, Heinrich Hertz and his radio-frequency, wavelengths, and light...

LEDs Rainbow Connection
View LED lights through the eyes of a scientist. Young scholars learn to view light as a wave frequency and connect various frequencies to different colors on the light spectrum. A lab activity asks groups to measure the frequency of...

Under the Ice: Imaging Glacier Bases with Sound
Students investigate with radio waves that are used to remotely sense the topography beneath the ice sheet. They experiment with travel time of waves and convert data to distance and depth. As a result, they develop a profile of the...

Determining Red-Shift in a Receding Star
Students practice manipulating algebra formulas with more than one variable. They examine the topics of velocity, wavelength and frequency. They determine the amount of red-shift in a receding star.
