[Grades 5-8] Energy is a property of many substances and is transferred in many ways Light [electromagnetic radiation] interacts with matter by transmission, absorption or reflection In most nuclear reactions, energy is transferred into or out of a system [Dawn Instrumentation Module] Orbital perturbations of the Dawn spacecraft caused by mass concentration changes—elevation and density—of surface and subsurface features of Vesta and Ceres cause Doppler shifts in radio waves which can be detected and used as basis for finding the mass concentration (gravity) of the two asteroids. The interaction of electromagnetic radiation with the surface features of Vesta and Ceres can be measured using VIR to detect mineral content (surface geology) Framing Cameras to form images of the surfaces GRaND to identify elements and water/ice in surface and sub-surface regolith/rocks [Grades 9-12] 
Waves, including sound and light waves, have energy and can transfer energy when they interact with matter. Electromagnetic waves include radio waves, infrared radiation, visible light, and gamma rays. Each kind of atom or molecule can gain or lose energy only in particular discrete amounts and thus can absorb and emit light only at wavelengths corresponding to these amounts. These wavelengths can be used to identify the substance.
