When teaching sound and related concepts to students with visual impairment, it is important to tie the concepts to real-life. This activity ties the concepts of wavelength, frequency (in Hertz), and pitch together using an on-line hearing test. It should be completed after these concepts have been introduced.
This activity also incorporates technology in a manner that interests the students and is entertaining.
- Wavelength: the distance from the top (crest) of one wave to the top (crest) of the next wave
- Frequency: the number of wave cycles/ second
- Hertz: a measure of the number of frequency cycles/ second
- Amplitude: the height of a wave
