Projects: COR, Standards First

Discipline: Science

Professional Commentary: Experimenting with solar collectors, cookers, and calculators, students discover the properties of light (radiant) energy from the sun. This investigation could be the beginning of a unit on the many forms of energy....

Projects: Standards First

Discipline: Science

Professional Commentary: This resource allows students to look at different kinds of materials; to identify the properties of materials and their suitability for different purposes. In this investigation, the familiar tale of The Three Little Pigs is used as an introduction to materials and manufacturing....
