Inner and Outer Planets

Scientists have put our planets into 2 categories: Inner and Outer. Students determined that the Inner Planets were Mercury, Venus, Earth, and Mars since they were closest to the sun. Then we determined that the Outer Planets were Jupiter, Saturn, Uranus, and Neptune. We made a model of the solar system (see previous posts). Based off of that model, we were able to conclude that the inner planets were warmer (because close to the sun) and smaller. Therefore, the outer planets are colder and larger.
