Explore how sound travels as a wave. Examine diagrams and simulations; answer questions about sound properties. Test the effects of changing wave properties: frequency, wavelength and amplitude. Transmit sounds in a range of mediums: air, water, steel or a vacuum. Find out how echolocation works. Measure speed and direction by using echo. This learning object is a combination of five objects in the same series.
Objective
Students use a wave model to explain the behavior of sound.
Students explore the basic properties of sound waves.
Students test the effects of varying sound wavelength, amplitude, frequency and medium density.
