P5 Generation Science – Good Vibrations

This afternoon P5 had Generation Science in to visit us to teach us all about sound and sound vibrations.

We discovered that everything is made up of particles, and for sound to move it needs to pass through the particles by bumping into each other. Sound can travel through gas, liquids or solids and it travels fastest through solids.

We also found out that higher pitched notes have waves that vibrate quicker than low pitched notes.

Even notes that we can’t hear still make sound vibrations.

Bigger vibrations make noises that are louder. E.g. hitting a drum harder.

The reason a guitar has a hole in the middle is so that the sound vibrations can be amplified by air in the box.

We recorded our own song using digital technology.
