Strand 8.2: ENERGY IS STORED AND TRANSFERRED IN PHYSICAL SYSTEMSObjects can store and transfer energy within systems. Energy can be transferred between objects, which involves changes in the objectís energy. There is a direct relationship between an objectís energy, mass, and velocity. Energy can travel in waves and may be harnessed to transmit information.
Develop and use a model to describe the structure of waves and how they are reflected, absorbed, or transmitted through various materials. Emphasize both light and mechanical waves. Examples could include drawings, simulations, and written descriptions of light waves through a prism, mechanical waves through gas vs. liquids vs. solids, or sound waves through different mediums.
