Energy Transfer and
Transformations – What is the role of energy in our world? 5.1 - Sound and light are
forms of energy. ¨
Sound is
a form of energy that is produced by the vibration of objects and is
transmitted by the vibration of air and objects. Light is a form of energy that travels in a straight line and can be reflected by a mirror, refracted by a lens, or absorbed by objects. |

main objective of this unit is to help students understand that sound waves
are produced by vibrations and vary in amplitude, frequency and wave length
and that they travel through matter. Ø Define
sound and describe how sound travels. Ø Explain
the various ways that messages can be communicated using sound waves. Ø Explain
the connection between sound and hearing
