Across
  1. 1. The starting ingredients in a chemical reaction.
  2. 3. How many bases taste.
  3. 4. A force that slows things down when they rub together.
  4. 7. Bases release these special particles in water(OH-).
  5. 10. When a reaction makes bubbles or a new smell.
  6. 12. A flat, sloping surface, like a ramp.
  7. 13. Acids release these special particles in water (H+).
  8. 16. Forces that are not equal, causing an object to change its motion.
  9. 17. The new things made in a chemical reaction.
  10. 19. Forces that are equal and opposite, so an object keeps its current motion.
  11. 20. The force of gravity pulling an object down.
  12. 21. A solid that forms from a liquid in a chemical reaction.
  13. 22. The force that pushes an airplane or rocket forward.
  14. 25. A sign of a chemical reaction when something looks different, like what bleach can do to clothing.
  15. 26. A simple machine like a doorknob or a car tire.
  16. 30. A gas made when some acids react with metals.
  17. 33. When an acid and a base mix to make water and a salt.
  18. 35. A wheel with a rope used for lifting things.
  19. 36. When a metal like silver slowly gets dull or dark.
  20. 38. How bases often feel to the touch.
  21. 39. When a reaction gives off heat or light.
  22. 44. Formed when H+ ions mix with water.
  23. 45. When you push something, that's the ______ force.
Down
  1. 2. Changes that make a brand new substance, like rust.
  2. 5. The force that pushes back when you apply an action force.
  3. 6. A simple machine like a seesaw or a crowbar.
  4. 8. Substances that can carry electricity when dissolved in water.
  5. 9. The rule that says energy cannot be made or lost, only changed.
  6. 11. An inclined plane wrapped around a cylinder, used to hold things.
  7. 14. The rule that says matter isn't made or lost in a reaction.
  8. 15. Energy that is stored and ready to be used.
  9. 18. These often feel soapy and taste bitter.
  10. 23. These taste sour and can turn litmus paper red.
  11. 24. The force that pushes back against something moving through air.
  12. 27. Bases turn red litmus paper this color.
  13. 28. Changes like melting or freezing; no new stuff is made.
  14. 29. Done when a force makes an object move a distance.
  15. 31. The upward force that helps an airplane fly.
  16. 32. Energy an object has because it is moving.
  17. 34. Acids turn blue litmus paper this color.
  18. 37. A simple machine used to split things, like an axe.
