A complete package that has students produce wave diagrams using a unique system of formulas (square counts) and standard grid paper. The emphasis is on the how sound wave properties of loudness (dB) and pitch (Hz) are represented respectively with variations in wave amplitude and wave length. Includes both audible frequencies and both ultrasonic and infrasonic frequencies. Includes lab introduction, procedure, data table, write up, score sheet and three companion Power Points. Excellent resource as an NGSS activity. Additional supplies needed include standard grid/graph paper and a ruler. Requires some prior knowledge regarding wave physics.
