Our last Science unit will be about the Physics of Sound.
The children will be looking at the following essential questions:
Investigation 1
- What are the properties of sounds that make them identifiable?
- Can you use the discrimination of sounds to make a code for sending messages?
- How are sounds made?
Investigation 2
- How are high and low sounds made?
- How does length affect the rate of vibration, and therefore the pitch?
- How does tension affect the rate of vibration, and therefore the pitch?
Investigation 3
- Can sounds travel through liquids?
- Can sounds travel through air?
- How is sound different when heard through air or water?
- Can sound travel through solids?
- How is sound different when heard through solids?
Investigation 4
- How can pitch,volume, and the distance a sound can travel be modified or enhanced?
The students will have a project to complete at home and a written assessment.
