Did you drink a glass of matter today? Do you carry your matter to school with you? What kind of matter do you like on your pizza? You probably don't think twice about the items you use on a regular basis, but all the stuff in the universe - from a tiny speck of dust on the floor to the stars far, far away in our galaxy - is made of matter. Well-known science writers Alvin and Virginia Silverstein and Laura Silverstein Nunn explain what is inside matter, how it forms different states, how it is defined with the elements of the modern periodic table, and how chemical reactions take place. The authors also reveal current research on matter, showing how scientists are finding ways to use substances - even garbage - to create brand new resources and substitutes for items with limited supplies.
