Across
- 1. energy from the sun
- 3. energy stored in the nucleus of an atom (forces of protons and neutrons held together, released when forces are overcome and particles are either removed from or added to the nucleus)
- 4. the energy of moving particles (hot cocoa has lots, ice-cold lemonade has less)
- 8. the ability to make things move or change
- 9. heat energy from inside the Earth that can used to heat buildings and produce electricity (natural hot springs and geysers)
- 11. energy of moving objects (car moving, ball rolling, fish swimming)
- 12. a change from one form to another
Down
- 2. energy of moving charges (lamps, toasters, computers, moves through wires)
- 5. energy that travels as waves, through matter or through empty space (Earth gets this from the sun)
- 6. energy of moving air (wind turbines)
- 7. energy stored in the bonds that hold atoms together in molecules (it is released when molecules undergo chemical reactions and form new substances) (Foods, fuels, and batteries store this energy)
- 10. energy of moving water (hydroelectric power plants use hydropower to produce electricity)
