Across
  1. 2. The distance between any two corresponding points that are adjacent on a wave
  2. 9. the energy an object has due to its motion
  3. 11. can travel through space (vacuum)
  4. 12. the transfer of the energy of a wave to matter as the wave passes through it
  5. 14. distance between the resting position and the maximum displacement of the wave
  6. 15. an educated guess about what will happen in your experiment
  7. 19. are the particles in an atom that has a neutral charge
  8. 20. a physical material that humans need and value
  9. 21. an elementary particle that has a negative charge of electricity and travels around the nucleus of an atom

  2. 3. how plants produce their food
  3. 4. the highest surface part of a wave
  4. 5. the ability to do work
  5. 6. is the change in direction of a wave passing from one medium to another caused by its change in speed
  6. 7. a deep cup or glass with a wide mouth and usually a lip for pouring
  7. 8. is a physical property that measures how closely packed together a substance's particles are
  8. 10. is an atomic particle that occurs in the nucleus of every atom and carries a positive charge equal in size to the negative charge of an electron
