SPS9. Students will investigate the properties of waves.
a. Recognize that all waves transfer energy. b. Relate frequency and wavelength to the energy of different types of electromagnetic waves and mechanical waves. c. Compare and contrast the characteristics of electromagnetic and mechanical (sound) waves. d. Investigate the phenomena of reflection, refraction, interference, and diffraction. e. Relate the speed of sound to different mediums. f. Explain the Doppler Effect in terms of everyday interactions. EQ: How can you compare and contrast different types of waves? Monday GMAS Testing in the morning resulted in an abbreviated schedule for all classes. Students reviewed work from Friday (Using notes from Waves and Electromagnetic Spectrum complete the practice working in small groups) and starting exploring how to use a spectroscope to break visible light into its separate wavelengths of color (ROY G BIV). Tuesday Mechanical Wave Machine Lab. Students worked in small groups to construct a mechanical wave machine using tape, bamboo skewers, ring stands, clamps, and different masses for the ends of the skewers to change the energy of the waves (mini marshmallows, gummy bears, and gum-balls). Wednesday Compare and contrast the different wave machines and and their energy based on mass. Review of frequency, wavelength, and wave speed. Thursday Practice for wavelengths and Electromagnetic Spectrum. Complete the IR on Waves.
