Sound and Vibrations — Interactive Lesson (Ages 8–9)

Why does a ruler twang when you flick it? This 31-slide interactive lesson helps Year 4 pupils understand sound and vibrations, from how sound is made to how our ears detect it.

Discovering Sound and Vibrations in Year 4 Science

Pupils learn that every sound is caused by something vibrating, from guitar strings to vocal cords, and that sound travels outward as waves through air, liquids and solids but not through empty space. They compare the speed of sound with the speed of light using thunder and lightning, find out how the ear senses vibrations and sends signals to the brain, and discover why sound waves cannot be seen.
