In this edition, our activities are linked to the natural environment. Our planet is constantly undergoing transformation, with the changing seasons, with the weather, but also through the actions of humans. What changes do you see in your natural environment? We’ll be making a miniature garden in a jar and finding out how Earth recycles water through our land, oceans and skies. We’re also collecting colourful autumn leaves to make beautiful pieces of art, and we meet Heather Stewart, who studies changes in the Earth at the bottom of the sea.
