This lesson introduces your child to the three key wave properties: amplitude (the height of a wave), frequency (how often a wave happens), and wavelength (the distance between wave peaks). These ideas are part of physics and explain how waves work in things like sound, light, and even mobile signals. Many children hear these terms in school but don’t always understand what they mean.

That’s where this home lesson comes in. I’ve broken the topic into simple parts, added fun and creative tasks, and included plenty of discussion ideas for you to work through together. You don’t need any special knowledge—everything is explained clearly and in plain English. Whether your child is 8 or 16, they’ll come away understanding how waves shape the world around us. All you need is curiosity, paper, and a bit of time.
