  1. 2. The ability to cause change in matter.
  2. 5. The process of using the senses to collect information. An observation is also a piece of information gathered using the senses.
  3. 7. The scientific study of matter and energy and how they interact.
  4. 11. An explanation for a natural phenomenon that is based on a body of facts and can be supported by the results of experiments.
  5. 12. A push or pull.
  6. 14. The pursuit of knowledge about the natural world and the application of that knowledge. Science is based on objective observations, investigations, and collected evidence.
  7. 15. A description of facts or observations that is accepted as true and can be used to predict future results. Scientific laws often use mathematical equations to describe relationships.
  8. 17. A neutral subatomic particle located in the nucleus of an atom.
  9. 19. The smallest particle of an element. An atom of a given element cannot be divided into smaller pieces that are still the same substance.
Down
  1. 1. A planned series of actions that test whether an idea is true.
  2. 3. A group of connected, interacting parts.
  3. 4. The base SI unit of mass. 1 kilogram (kg) is equal to 1,000 grams (g).
  4. 6. A method of writing very small or large numbers using powers of 10.
  5. 8. A negatively charged subatomic particle located outside the nucleus of an atom.
  6. 9. A positively charged subatomic particle located in the nucleus of an atom.
  7. 10. The SI unit for energy, named after physicist James Prescott Joule.
  8. 13. The use of scientific knowledge for practical purposes.
  9. 16. Anything that takes up space and has mass.
  10. 18. The SI unit used to measure force.
