D. Pressure not addressed at this grade level. The use of energy and its products affect the lives of all peoples of the world. Different parts of the world have different amounts and kinds of energy resources to use and use them for different purposes. Energy transformations occur at both micro- and macro levels. Energy can neither be created nor destroyed.
Energy can change from one form to another.
Moving objects have kinetic energy. An object has potential energy because of its position. Make a Rube Goldberg device and describe the energy transfers involved. Heat moves in predictable ways from warmer objects to colder objects. Heat can be transferred through materials by the collisions of atoms, across space by radiation, or by movement of fluids.
