Across
  1. 2. An element that is an excellent conductor of heat and electricity, can be hammered into sheets, found on the left side of the Periodic Table.
  2. 4. Like matter, this cannot be created or destroyed, it can only change form.
  3. 6. Newton’s law that explains inertia; an object in motion will stay in motion, and an object at rest will stay at rest unless an unbalanced force acts upon it.
  4. 7. Forces Forces that cause a change in motion.
  5. 10. The change of state from a gas to a liquid.
  6. 12. A state of matter where particles move the slowest.
  7. 18. The ability of living things to make more of their own kind.
  8. 20. Forces Forces that are equal and opposite, causing no movement.
  9. 22. Change A change that forms a new substance with different properties.
  10. 24. The amount of space an object takes up.
  11. 25. A state of matter with electrically charged particles.
  12. 27. The smallest whole piece of matter.
  13. 28. Point The temperature at which a solid becomes a liquid.
  14. 30. The tendency of an object to resist changes in motion.
  15. 32. A mixture that is uniformly distributed.
  16. 33. A state of matter with definite volume but no definite shape.
  17. 35. Newton’s law that explains how force, mass, and acceleration are related.
  18. 37. Number The number of protons in an atom’s nucleus.
  19. 38. The change of state from a liquid to a gas.
  20. 39. A characteristic of living things where organisms can develop.
  21. 42. A mixture that is not uniformly distributed.
Down
  1. 1. How tightly packed matter is; mass divided by volume.
  2. 2. Two or more substances physically combined but not bonded.
  3. 3. A push or pull measured in newtons.
  4. 5. How living things react to stimuli in their environment.
  5. 8. Mass The number of protons and neutrons in an atom’s nucleus.
  6. 9. A state of matter with no definite shape or volume.
  7. 11. An element that is brittle and a poor conductor, found on the right side of the Periodic Table.
  8. 13. How cells become tissues and tissues become organs and organs become systems.
  9. 14. Words & Clues (Unit 2 Science)
  10. 15. A living thing.
  11. 16. A substance with a pH less than 7.
  12. 17. The change of state from a liquid to a solid.
  13. 19. The amount of matter in an object.
  14. 21. A substance made of two or more elements chemically bonded together.
  15. 23. A substance with a pH greater than 7.
  16. 26. Anything that has mass and takes up space.
  17. 29. A change in speed or direction.
  18. 31. Newton’s law that explains how for every reaction is there is an equal and opposite reaction.
  19. 34. A positively charged particle in the nucleus of an atom.
  20. 35. Scale A tool used to measure force.
  21. 36. Point The temperature at which a liquid becomes a solid.
  22. 40. Change A change where the substance stays the same but its form changes.
  23. 41. The gravitational pull on an object.
