Rocks and the Changing Earth
Earth science with Millie and her kitten Biscuit, at a grade 4 level: rocks and minerals and how hard they are, the three kinds of rock, fossils, what soil is made of, how weathering breaks rock and erosion carries it away, volcanoes and mountains, and the layers deep inside Earth.
Every card is a little story: “Mia drops a light, bubbly grey rock into the castle pond and it floats! Which rock is it?” Each topic has its own world, from the Fairy Garden to Mermaid Lagoon, and a big seek-and-find picture to explore.
