Across
  1. 2. state of matter where something has a definite shape because molcules are tightly packed and slow moving
  2. 6. after wood inventions, people started using this material to make things
  3. 8. can happen when heat is applied to a solid
  4. 9. things that cannot make their own energy
  5. 10. a shovel, seesaw, and human arm are this type of simple machine
  6. 13. plants rely on this part for reproduction
  7. 16. Flying mammal
  8. 19. when precipitation travels down a mountain to a lake, puddle, or ocean
  9. 21. the part of the water cycle that includes puddles, lakes, ponds, oceans
  10. 22. measures liquid
  11. 23. the phase of the moon after full moon and before another new moon in which we only see halfof the bright side
  12. 24. types of energy where natural processes can replace them in a reasonable amount of time (hydro, wind, solar, biomass, geothermal)
  13. 26. happens in the water cycle when water vapor starts to cool down (clouds)
  14. 28. can happen when a liquid is cooled down enough
  15. 31. state of matter with many molecules that move past each other easily, and it takes the shape of it's container
  16. 32. when the moon goes through phases in which it appears to be getting smaller
  17. 34. the phase of the moon in which we can see the entire bright side of the moon
  18. 36. this is what rocks are made of
  19. 37. the part of our water supply that is located under the surface of the earth in the soil and between rocks
  20. 39. A way to convert waste into a useable material
  21. 40. a soft metal core made into a magnet by the passage of an electric current through a coil surrounding it, and more coils make it stronger
  22. 41. Investigation in order to conduct this, it is important to prepare, do, observe, and record.
  23. 42. type of energy that we need to conserve, because they cannot be placed in a reasonable period of time, if at all (coal, petroleum, natural gas, oil)
  24. 44. this explains how wet dishes left out over night are dry in the morning
  25. 45. when the moon goes through phases in which it appears to be growing larger
  26. 46. type of energy that can be produced by rubbing your hands together
  27. 48. things that can make their own energy through photosynthesis
  28. 49. part of the plant that provides support, and tranports fluids to leaves
  29. 50. source of energy for the water cycle
Down
  1. 1. state of matter where molecules are very spread out and moving, and it takes the shape of it's container
  2. 3. part of the plant that provides energy
  3. 4. traits that plants and animals can "learn" to do or that can happen to them regardless of genes
  4. 5. Large marsupial
  5. 7. traits that plants and animals are born with, and they could not choose
  6. 11. part of a plant that collects water and nutrients, and acts as an achor
  7. 12. the part of the water cycle which includes rain, sleet, snow, hail
  8. 14. early inventions were made of this material
  9. 15. this is what mirrors do
  10. 17. in a lake ecosystem, this is a producer that must fight for sunlight
  11. 18. after metal inventions, this material was discovered and used to make things
  12. 20. a moon phase after new moon and before full moon in which we only see half of the bright side
  13. 25. Has a trunk
  14. 27. Man's best friend
  15. 29. these can enter our body thorugh our nose, eyes, mouth, cuts or scrapes, or bug bites
  16. 30. the human body's purpose for skin
  17. 33. an axe, scissors, and knife are this type of simple machine
  18. 35. plants found in these areas probably need long roots to search for water
  19. 38. Likes to chase mice
  20. 43. the first phase of the moon where we do not see any of the bright side of the moon (appears dark)
  21. 47. the prcess of wearing away the earth's crust, can be caused by wind, glaciers, or water
