PHYSICS OF SOUND
The Physics of Sound Module consists of
four sequential investigations, each designed to expose a
specific set of concepts. Students learn to discriminate between
sounds generated by dropped objects, how sounds can be made
louder or softer and higher or lower, how sounds travel through
a variety of materials, and how sounds get from a source to
a receiver. The investigations provide opportunities for students
to explore the natural and humanmade worlds by observing and
manipulating materials in focused settings using simple tools.
FOSS EXPECTS STUDENTS TO
- Observe and compare sounds to develop discrimination ability.
- Communicate with others using a drop code.
- Learn that sound originates from a source that is vibrating
and is detected at a receiver such as the human ear.
- Understand the relationship between the pitch of a sound
and the physical properties of the sound source (i.e. length
of vibrating object, frequency of vibrations, and tension
of vibrating string).
- Compare methods to amplify sound at the source and at
- Observe and compare how sound travels through solids,
liquids, and air.
- Use knowledge of the physics of sound to solve simple
- Acquire vocabulary associated with the physics of sound.
- Exercise language, social studies, and math skills in
the context of the physics of sound.
- Develop and refine the manipulative skills required for
- Use scientific thinking processes to conduct investigations
and build explanations: observing, communicating, comparing,
