Students will use computer-based laboratory tools to measure sound wave properties such as the time for a pattern to repeat, wavelength, frequency, amplitude, and the velocity of the wave.

*Constancy, Change, and Measurement

Students will brainstorm to list the factors necessary for "heat lightning" to occur. This phenomenon - observing lightning without hearing thunder- occurs during a period of hot weather. Students will conduct research to explain this phenomenon.

*Constancy, Change, and Measurement

Students will explore the properties of transverse and longitudinal waves in strings and springs. They will use a ripple tank apparatus and/or computer simulation of a ripple tank to explore the properties of waves that are generated in water.

*Constancy, Change, and Measurement

Students will determine the speed of sound by using the principle of resonance. Students will use an apparatus consisting of a vibrating tuning fork over an open PVC tube of water.

*Constancy, Change, and Measurement

*Unifying Concept (NSES) represented in this activity. Unifying concepts cross curricular areas and provide students with productive and insightful ways of thinking about and integrating basic ideas that explain the natural and designed world.
