Students can actually change what happens in the video, selecting and varying a parameter like the mass of the object or the frequency of the wave, and observe how this change affects the outcome.
Students use interactive measurement tools such as rulers and a stopwatch to decide for themselves what and how to measure.
Students learn about transverse mechanical waves, how to measure the speed of a wave, and the relationship between the frequency of a wave and the wavelength.
Students measure the total power output of the sun by comparing the intensity of the Sun’s light at Earth’s surface to the intensity of a known source of light.
