MS.2. Physical Science: Understand relationships of the properties of objects and materials, position and motion of objects, and transfer of energy to explain the physical world.
2.d. Categorize examples of potential energy as gravitational (e.g., boulder on a hill, child on a slide), elastic (e.g., compressed spring, slingshot, rubber band), or chemical (e.g., unlit match, food). (DOK 2)
2.g. Categorize materials as conductors or insulators and discuss their real life applications (e.g., building construction, clothing, animal covering). (DOK 2)
