Vibrations and waves
Learners explore the nature of sound, light and radiations in the electromagnetic spectrum. They use musical instruments to explore the relationship between vibrations and sounds produced. They develop their understanding of the properties of light and other forms of electromagnetic radiations. They explore how different waves relate to the environment and how we make use of them in health, medicine and communications.

Through play, I have explored a variety of ways of making sounds.
|
By collaborating in experiments on different ways of producing sound from vibrations, I can demonstrate how to change the pitch of the sound.
|
Through research on how animals communicate, I can explain how sound vibrations are carried by waves through air, water and other media.
|
|
By recording and analysing sound signals, I can describe how they can be manipulated and used in sound engineering.

By exploring reflections, the formation of shadows and the mixing of coloured lights, I can use my knowledge of the properties of light to show how it can be used in a creative way.
|
By exploring the refraction of light when passed through different materials, lenses and prisms, I can explain how light can be used in a variety of applications.
|
By carrying out a comparison of the properties of parts of the electromagnetic spectrum beyond the visible, I can explain the use of radiation and discuss how this has impacted upon society and our quality of life.

By exploring radiations beyond the visible, I can describe a selected application, discussing the advantages and limitations.
