WA.4. Physical Science
PS3. Energy: Transfer, Transformation, and Conservation
2-3.PS3. Forms of Energy: Students learn to identify several different forms of energy. Children in this age range have an intuitive understanding of energy concepts. For example, energy is needed to get things done; humans get energy from food. It is possible to build on these ideas by having the students explore different energy phenomena.
2-3.PS3A. Students know that heat, light, motion, electricity, and sound are all forms of energy.
2-3.PS3A.3. Students are expected to explain how light, sound, and motions are all energy.
