Everything is matter, and matter is everything. Stuff! is where kids explore these ideas and so much more, starting with the basics of what actually “counts” as matter, including the question of whether light “counts” as matter.

Not only do kids explore the different forms of matter – solids, liquids, and gases – through intriguing examples from their everyday lives, they also take a deeper look at the properties of matter and the properties that make particular materials suited for particular tasks. Can matter change from one form to another? Can it be put together, taken apart, and reassembled? You bet, and it’s all here in Stuff!
