Answers: What do meteorites look like?

  1. D: Lumpy, with smooth rounded edgesMeteorites are rarely perfectly round; they are often lumpy with smooth, rounded edges.
  2. A: Yes, a few rare ones hardly react at allSome rare meteorites, such as many from the Moon and Mars, hardly react to a magnet.
  3. C: Fusion crust and thumbprint dentsBoth the fusion crust and regmaglypts form as the air melts the surface during the fall.
  4. B: They kept pointing the same way as they fellThese meteorites kept the same side forward, so the rushing air shaped their front.
  5. False: the right answer is It might be a meteorite, but an expert must checkWeight and magnetism are clues, not proof, because some Earth rocks are heavy and magnetic too.
  6. False: the right answer is The air melts and scoops away the surface unevenlyRegmaglypts form during the fiery fall, when the air melts and removes the surface unevenly.
  7. You watch whether the magnet swings towards the rock (accept any answer with the same meaning)Hang a strong magnet on a string near the rock and see if it is pulled towards it.
  8. The melted outside cools into a skin as the rock slows (accept any answer with the same meaning)The outside melts during the fall, then cools quickly into a thin skin once the rock slows down.

Task

Answers will vary. The task comes from the lesson: Tie a fridge magnet to a piece of thread. Dangle it near different things around your home: a spoon, a coin, a stone from the garden. Which ones pull the magnet? Do not test rocks belonging to museums or other people without permission.

Look for work that uses the key words correctly and gives a reason for each point.
