The Hands-on Waves, Sound, and Light unit will help students understand the world around them through inquiry and hands-on experimentation. The major concepts covered will be waveforms, measures of a wave, interference, reflection, standing waves, refraction, diffraction, Doppler shift, bow/shock waves, sound transmission, wave speed, loudness and pitch, resonance, beats, electromagnetic spectrum, speed of light, luminous bodies, transparent materials, color, pigments, shadows, polarization, mirrors, images, lenses, and the eyeball. The unit takes 5-6 weeks, averaging 45 minutes a day if meeting 5 days/week. The unit is a stand-alone and/or could be used to accompany a number of texts. The unit is structured around the lab work and in-class activities. Many of the activities are inquiry or discovery-based. They attempt to allow students to discover the laws of science involved in the unit. Everything has been provided as a Word 1997-2004 .doc document for compatibility.
The Waves, Sound, and Light unit should be proceeded by:
1. Topics to be taught:
2. Skills to be taught:
The entire unit should take about 5-6 weeks, averaging 45 minutes a day if meeting 5 days/week. The timing of the unit revolves around the lab work and in-class activities. The labs/activities are arranged in numerical order. The homework reinforces the lab work and in-class activities and should be assigned accordingly. The notes could be given as a reference at the start of the unit or as a lecture at the end. The review games prepare students for the group quiz and unit exam.
