Sound Waves and Hearing — Interactive Lesson (Ages 11–14)

Talking drums, car horns and music all reach your ears as longitudinal waves. This 18-slide interactive lesson on sound waves takes pupils from first ideas to exam-style explanations, with 9 self-marking activities and nothing to prepare beforehand.

Teaching Sound Waves and Hearing in KS3 Science

Pupils explain that sound is made by vibrations and travels as a longitudinal wave that needs a medium, and compare its speed in solids, liquids and gases. They link frequency to pitch and amplitude to loudness using oscilloscope traces, follow sound through the parts of the ear, and describe the range of human hearing, ultrasound and echoes.

What Pupils Will Learn

• Explain that sound is made by vibrations.
• Describe how sound travels as a longitudinal wave through a medium.
• Link frequency to pitch and amplitude to loudness.
• Describe how the ear detects sound.
• Describe ultrasound and the range of human hearing.
