Conservation8.2.3.f. Describe transfer of energy from electrical and magnetic sources to different energy forms (heat, light, sound, chemical)8.2.3.g. Recognize all energy is neither created nor destroyed
Heat8.2.3.e. Recognize that heat moves from warmer objects to cooler objects until both reach the same temperature
Light8.2.3.c. Recognize that light interacts with matter by transmission (including refraction), absorption, or scattering (including reflection)8.2.3.d. Recognize that to see an object, light from the surface of the object must enter the eye; the color seen depends on the properties of the surface and the color of the available light sources
Sound/Mechanical Waves8.2.3.a. Recognize that vibrations set up wave-like disturbances that spread away from the source (sound, seismic, water waves)8.2.3.b. Identify that waves move at different speeds in different materials
