Waves & Their Applications in Technologies
Learning Targets
-I can understand that a sound wave needs a medium through which it is transmitted (can’t travel through space). MS-PS4-2.a
-I can understand that because light can travel through space, it cannot be a matter wave, like sound or water waves. MS-PS4-2.b
-I can understand that a simple wave has a repeating pattern with a specific wavelength, frequency, and amplitude. MS-PS4-1.a
-I can use a wave model to understand that light travels in straight lines, except where the light path changes direction due to refraction. MS-PS4-2.c
-I can describe how waves are reflected, absorbed, and transmitted through various materials. MS-PS4-2.d
-I can develop and use a model to show wave reflection, absorption, and transmission. MS-PS4-2.e
-Develop and use models. SEP.6-8.2
-I can use math to show how the amplitude of a wave is related to the energy in a wave. MS-PS4-1.b
-Use mathematics and computational thinking. SEP.6-8.5
-I can understand that a wave model of light is useful for explaining brightness, color, and frequency. MS-PS4-2.f
-I can use a wave model of light to explain brightness, color, and frequency. MS-PS4-2.g
-I can understand the difference between analog and digital technology. MS-PS4-3.a
-I can prove that digitized signals (sent as wave pulses) are a more reliable way to encode and transmit information than analog technology. MS-PS4-3.b
-I can obtain, evaluate, and communicate information. SEP.6-8.8 (I can use written text and visual displays to clarify claims and findings and prove that digitized signals are more reliable than analog signals.)
-I can understand that technology influences the progress of science and science influences the advance of technology. MS-PS4-3.c
