Sound

What does vibration mean? Identify how sounds are made, associating some of them with something vibrating. 

How does the ear work? Recognise that vibrations from sounds travel through a medium to the ear.

How is sound measured? Recognise that vibrations from sounds travel through a medium to the ear.

How does the strength of vibrations affect the volume of a sound? Find patterns between the volume of a sound and the strength of the vibrations that produced it.

What is pitch? Find patterns between the volume of a sound and the strength of the vibrations that produced it. Working scientifically − Identifying differences, similarities or changes related to simple scientific ideas and processes.

How does the distance from the sound source affect the volume of the sound? Recognise that sounds get fainter as the distance from the sound source increases.

Can we block sound?

• Use scientific vocabulary to report and answer questions about their findings based on evidence collected, draw simple conclusions and identify next steps, improvements and further questions.

• Begin to choose which observations to make and for how long and make systematic, careful observations and comparisons, identifying changes and connections.

• Construct operational simple series circuits using a range of components and switches for control.

• Explain how sounds are made and heard using diagrams, models, written methods or verbally.

How can we change a sound?

• Use scientific vocabulary to report and answer questions about their findings based on evidence collected, draw simple conclusions and identify next steps, improvements and further questions. 

• Compare and find patterns in the pitch of a sound, using a range of equipment, such as musical instruments.

• Explain how sounds are made and heard using diagrams, models, written methods or verbally.

How far can sound travel?

• Use scientific vocabulary to report and answer questions about their findings based on evidence collected, draw simple conclusions and identify next steps, improvements and further questions.

• Compare how the volume of a sound changes at different distances from the source.

• Take accurate measurements in standard units, using a range of equipment.

• Compare and find patterns in the volume of a sound, using a range of equipment, such as musical instruments.
