Across
  1. 5. The action of walking on grass in bare feet; allowing the built up charges in out bodies to be released and soaking up the earth's energy through your soles.
  2. 6. a device for making or breaking the connections in an electrical circuit
  3. 10. made by Volta of copper and zinc plates with salt water solution between
  4. 12. flow of electrons
  5. 13. the lines of force surrounding a permanent magnet
  6. 16. salts dissolved in water, conducts electricity due to presence of ions
  7. 18. two unlike poles pull toward each other
  8. 19. converts kinetic energy into electrical energy
  9. 20. mechanical, solar, kinetic, sound, light, thermal,electrical, etc
  10. 22. a piece of material (such as iron or steel) that attract
  11. 23. substance capable of transmitting light, electricity, heat, or sound
Down
  1. 1. positively charged particle in an atom
  2. 2. measures how well a material or object conducts electricity
  3. 3. a pathway made of wires that electrons can flow through. There has to be a connection of the negative end to the positive end of a power source.
  4. 4. measurement of current, flow of electric chargeover time through a givne point in an electric circuit
  5. 7. one of the three metals that are attracted to a magnet
  6. 8. the build up of an electrical charge on the surface of an object. The charges remain in one area for a while rather than moving or "flowing" to another area.
  7. 9. measurement of electric pressure, electric force that causes electrons to flow
  8. 11. a material that is a poor conductor of electricity, heat, or sound.
  9. 12. a piece of iron encircled by a coil of wire through which an electric current is passed to magnetize the iron
  10. 14. a sort of container that stores energy until it is needed.
  11. 15. converts electrical energy into knietic energy
  12. 16. negatively charged particle in an atom
  13. 17. measurement of power over time or how much power is used
  14. 18. the basic building blocks of all matter,cannot be divided into smaller parts by ordinary means.
  15. 21. two like poles push each other away
