STC Literacy Series™: Balancing and Weighing

0.00 - 0.00

Grades K–2. 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.


Introduce children to the relationship between balance and weight.

Grades K–2. The text explores how an object's mass, the length of a lever arm, and the position of a fulcrum affect balance. It explains weighing as the process of balancing an object against a certain number of standard objects. The book provides many examples of balancing and weighing in everyday life, showing how different object compare to each other.

Developed to enhance the teaching of the Science and Technology Concepts™ (STC™) unit, the STC Literacy Series™ Balancing and Weighing reader supports inquiry-based science lessons with engaging informational text. The content gives students a natural transition from hands-on investigations, builds background knowledge to reinforce conceptual learning, and lets students apply relevant nonfiction to their own real-world experiences. Questions provided throughout the book encourage critical thinking and allow children to be actively involved in their learning.

Educational studies show that children are more likely to engage in a reading exercise when the literature is related to a recent hands-on activity. This is exactly how the STC Program™ works. Included in every STC-Elementary™ kit, the STC Literacy Series™ helps improve reading comprehension, and supports the following Common Core Standards:

  • RI.1-3
  • RI.4-6
  • RI.7-9

Balancing and Weighing paper version (item #971796) comes as a pack of 8 readers. Balancing and Weighing electronic version (item #971796E32) allows 32 students per year to have access to the text for 60 months.
