This World of Things follows curious Khushi in her sunlit classroom as she wonders what desks, windowpanes, hinges, books and clothes are made of and where those materials come from. Students explore materials like wood, metal, glass, plastic, rubber, clay and fabric, test properties such as transparency (transparent, translucent, opaque) and flexibility, and distinguish solids, liquids and gases.

FAQ
Why are windowpanes made of glass instead of wood?
Glass is transparent, so it lets sunlight into the room and allows us to see outside while keeping wind and dust out.
What is the difference between a solid and a liquid?
A solid (like a brick or wooden block) keeps its own fixed shape, while a liquid (like water or milk) flows and takes the shape of its container.
