Across
  1. 4. Motion, The way something appears or seems to move
  2. 5. The place in an ecosystem where an organism lives
  3. 6. Change, Begins and ends with the same matter
  4. 7. Phases, The apparent shape of the moon in the sky; the moon cycles through all of its phases during one orbit
  5. 8. Dioxide, A colorless gas made of carbon and oxygen; released by animals and used by plants
  6. 10. Property, characteristic that can only be observed when there is a change in matter
  7. 12. of Mass, The law that states matter is neither created nor destroyed during a physical or chemical change
  8. 14. The solid parts of Earth (rocks, soil, mountains, and land)
  9. 15. Organisms that use energy from the sun to make their own food
  10. 21. Mixture, A mixture that is uniform throughout; you cannot take it apart
  11. 22. Organisms that cannot make their own food
  12. 26. All the water on Earth
  13. 29. Year, A measurement of distance; the distance light travels in one year
  14. 30. The ability of matter to be attracted
  15. 31. Species, An organism introduced to a new ecosystem that causes harm
  16. 33. The ability of matter to dissolve in a liquid
  17. 34. Variable, The variable(s) that are kept the same
  18. 37. Chain, A model showing a series of feeding relationships and how energy moves
  19. 43. The amount of matter in an object
  20. 44. Data, Data or information that is observed
  21. 45. The ability to perform work or change something; the “fuel” that makes things work
  22. 46. Anything that has mass and takes up space
  23. 47. Variable, The variable that you change
  24. 48. Matter with no definite shape or volume; particles move freely
  25. 49. Web, A model showing how multiple food chains are linked together
  26. 50. Was your hypothesis correct?
  27. 53. Matter with a definite volume but no definite shape
  28. 54. The regular rise and fall of water along the shore; Earth’s gravity and the moon’s gravity are both pulling water toward them
  29. 55. Organisms that hunt for food
  30. 56. Data, Data that is collected by counting or measuring
  31. 59. The amount of space an object takes up (not the same as weight)
  32. 60. When sediment is dropped or left behind in a new place
  33. 62. Tiny openings on the underside of leaves that allow air to enter; close to prevent water loss
  34. 64. Factors, All of the non-living things in the environment
  35. 65. Particles of matter move closer together
  36. 66. Matter with a definite shape and volume
  37. 67. A type of organism made up of a single cell
Down
  1. 1. A procedure to test your hypothesis
  2. 2. The part of a meteor that does not burn up in the atmosphere and hits the ground, leaving craters in Earth’s surface
  3. 3. The layer of air that surrounds Earth
  4. 9. When water, wind, or ice slowly wears away and moves rock or soil to a new place
  5. 11. Mixture, A mixture with parts that are not uniformly mixed; you can take it apart
  6. 13. A type of heterogeneous mixture that looks the same throughout but particles settle over time
  7. 16. How energy can move through matter
  8. 17. One complete spin on the Earth’s axis; makes one rotation every 24 hours
  9. 18. The evaporation of water from a plant’s leaves
  10. 19. An educated guess about the outcome of the experiment that answers the question
  11. 20. Patterns in the sky made by stars; there are 88 recognized constellations
  12. 23. The way light bounces off of matter
  13. 24. Change, creates new matter
  14. 25. Organisms hunted by predators
  15. 27. Particles of matter move farther apart
  16. 28. Gathering information about your question or topic
  17. 32. All the living things on Earth (plants, animals, and people)
  18. 35. Organisms that break down materials into simpler substances
  19. 36. Property, A characteristic of matter that can be observed or measured
  20. 38. Cycle, The circulation of oxygen and carbon dioxide gases
  21. 39. Anything that can change or be changed
  22. 40. One complete pass of the Earth around the sun; takes the Earth 365¼ days
  23. 41. Variable, The variable that is observed
  24. 42. What you want to learn more about and get an answer to
  25. 43. A space rock that enters Earth’s atmosphere and burns up, usually hitting the ground (sometimes called “shooting stars”)
  26. 51. Factors, All of the living things in an environment
  27. 52. A force of attraction or pull between any two objects; pulls to the center of the Earth
