  1. 2. - the amount of matter that makes up an object, usually measured in grams (g)
  2. 5. - how something feels when it is touched
  3. 6. planets - The outer planets are Jupiter, Saturn, Uranus, and Neptune. These planets are much larger than the inner planets and are made primarily of gases and liquids.
  4. 8. - the scale of temperature in which water freezes at 0° and boils at 100°
  5. 14. - When a magnetic pole repels another magnetic pole, it gives out a force that pushes the other pole away.
  6. 15. - the scale of temperature in which water freezes at 32° and boils at 212°
  7. 17. planet - The four planets closest to the Sun—Mercury, Venus, Earth, and Mars. They are all made of metal and rock.
  8. 18. – matter in a state in which it flows and takes on the shape of the container in which it is placed.
  9. 20. - A mixture contains two or more substances that are not chemically combined. The substances in a mixture can be separated using physical methods such as filtration, freezing, and distillation.

  1. 1. - When a substance is added to a liquid to form a solution. The substance seems like it disappears when in fact it is being broken down into pieces so small that we cannot see them anymore.
  2. 3. - the amount of space matter takes up, usually measured in milliliters (ml) for liquids and cubic units for solids.
  3. 4. - "Revolution" refers the object's orbital motion around another object. Earth revolves about the Sun, producing the 365-day year.
  4. 7. – matter in a state in which it will expand freely to fill the whole of a container, having no fixed shape (unlike a solid) and no fixed volume (unlike a liquid).
  5. 9. matter is a state where it has a fixed shape and fixed volume, which means they don't move to fill a container when they're placed in it or expand out. They hold their own shape and volume.
  6. 10. - the curved path of an object around a star, planet, or moon.
  7. 11. - "Rotation" refers to an object's spinning motion about its own axis. For example, Earth rotates on its own axis, producing the 24-hour day.
  8. 12. - small objects made up of rocky objects that orbit the Sun.
  9. 13. - large objects made of dust and ice that orbit the Sun. Best known for their long, streaming tails.
  10. 16. - means light completely passes through it, and you can see /through it.
  11. 19. - a huge collection of gas, dust, billions of stars and their solar systems, all held together by gravity. We live in the one called the Milky Way.
