Next Generation Science Standards (NGSS Comprehensive)
NGSS.4-PS. PHYSICAL SCIENCE
4-PS3. Energy - Students who demonstrate understanding can:
4-PS3-1. Use evidence to construct an explanation relating the speed of an object to the energy of that object.
4-PS3-2. Make observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents.
4-PS3.DCI. Disciplinary Core Ideas
PS3.A: Definitions of Energy
PS3.A:1. The faster a given object is moving, the more energy it possesses. (4-PS3-1)
PS3.B: Conservation of Energy and Energy Transfer
PS3.B:1. Energy is present whenever there are moving objects, sound, light, or heat. When objects collide, energy can be transferred from one object to another, thereby changing their motion. In such collisions, some energy is typically also transferred to the surrounding air; as a result, the air gets heated and sound is produced. (4-PS3-2), (4-PS3-3)
