Light and Sound
Light and sound with Millie and her kitten Biscuit, at a grade 4 level: what makes its own light and what only bounces it, why shadows form, transparent, translucent and opaque things, mirrors and reflection, how a prism makes a rainbow, sound as vibration, loud and soft, high and low notes, and how echoes and sound travel through air, water and solids.
Every card is a little story: “Octavia grabs her crashing cymbal with one arm and the sound stops. Why?” Each topic has its own world, from the Star Tower at night to Echo Valley, and a big seek-and-find picture to explore.
