Learning Goals & Assessments
VDOE - SOL's targeting Waves: >> applications of sound waves. Key concepts include >> a) wavelength, frequency, speed, and amplitude; >> b) resonance; >> c) the nature of mechanical waves; and >> d) technological applications of sound. >> Key concepts include >> a) the wave behavior of light (reflection, refraction, diffraction, and interference); >> b) images formed by lenses and mirrors; and >> c) the electromagnetic spectrum. >> waves to interpret wave phenomena. Key concepts include >> a) wave characteristics (period, wavelength, frequency, amplitude, and phase); >> b) fundamental wave processes (reflection, refraction, diffraction, interference, polarization, >> Doppler effect); and >> c) light and sound in terms of wave models. >> electromagnetic spectrum are phenomena ranging from radio waves through visible light to >> gamma radiation. Key concepts include >> a) the properties and behaviors of radio waves, microwaves, infrared, visible light, ultraviolet, >> X-rays, and gamma rays; and >> b) current applications based on the wave properties of each band. >> the fundamental processes of reflection, refraction, and image formation. Key concepts include >> a) application of the laws of reflection and refraction; >> b) construction and interpretation of ray diagrams; >> c) development and use of mirror and lens equations; and >> d) predictions of type, size, and position of real and virtual images.

Lesson Plans Draft
Scope / Sequence Telegraph - Square waves Relay - little circuit to big circuit Solenoid - current makes something move Motor - current makes something spin Generator - mechanical energy to electrical energy Wind Turbine - blades turn generator

Speaker - uses a solenoid to make sound CENTRAL CONCEPT: Waves are back-and-forth movement Examples - Vibrating Ruler / Tuning Fork / Guitar String Periodic v Aperiodic Pure Tone v Complex Waveform

Acquire other kinds of data from other sensors Display other kinds of waveforms

Technology / Materials
Brainstorm of *possible* items:
 * home-made speaker
 * amplifier
 * commercial microphone
 * signal-processing circuit
 * Arduinos
 * tuning forks
 * possibly use GB / BF's JavaSonics license

Scholarship

 * 5 pg max
 * What has to be taught in Middle School Physical Science?
 * Key issue: How to link abstraction to the actual event? ( link actual sine wave to event...)
 * What is //some// of existing research?
 * How might we best link science concepts to engineering design, in light of what has done before?
