STC Literacy Series™: Balancing and Weighing

Did you know that the adult human brain weighs about 3 pounds? Or that cheetahs can change direction in midair when chasing prey? Using engaging, real-world examples like these, Balancing and Weighing from the STC Literacy Series™ gets young students interested in basic physical science. The text explores balance and helps children discover that it is affected by 3 variables—the mass of an object, the length of the lever arm, and the position of the fulcrum.
