Your investigation

  1. Make five headings: star, planet, dwarf planet, moon, small Solar System body.
  2. Place Sun, Earth, Neptune, Pluto, Moon, an asteroid, and a comet under headings.
  3. Write one reason for every placement. Make an “I need more evidence” box for an unknown object.
  4. Invent a clue for one object and ask a partner to classify it.

Think, draw, explain

Can an object be important even if it is not a planet?

What evidence would help classify an unfamiliar object?

Compare your explanation with the grown-up answer guide after you have tried.
