Lesson 10: The planets and their paths

Grades 3–5 · about 15 minutes · NGSS 5-ESS1-1, toward MS-ESS1-3. By the end: I can name the planets in order and explain that the farther a planet is, the longer its year.

Learn

  1. Eight planets travel around the Sun, each on its own path: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.
  2. The first four are small and rocky. The last four are giants, made mostly of gas and ice.
  3. The farther a planet is, the longer its year: Mercury goes around in 88 days, Earth in one year, and Neptune takes about 165 years.
