Bell Work: Happy Monday! ***I am going to come around and check the Astrologic puzzles that were to be finished over the weekend.*** 1. Why do we have high and low tides? 2. What do we call the movement that the earth makes around the sun? Around its axis? 3. According to your Astrologic Puzzle, what planet has the most moons?

Notes Set- Up ** Next available page, label Planetary Motion. ** The pages after that we are going to glue in all of the planets in order. ** Wait for instructions on how to glue these in properly. ** After Mars, be sure to label a page as Asteroids, Comets and Meteoroids.

Answer this! What keeps the planets in orbit on a path around the sun? What keeps the moon orbiting around the Earth?

Gravity and Inertia Gravity is a force that pulls the object (planet) toward whatever it is orbiting around (sun). Inertia is a force that wants the object to keep in a forward motion in a straight line. Both together, result in a elliptical (oval) orbit path.

The Planets We now have only eight planets! My Very Educated Mother Just Served Us Nachos! Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune Pluto is now a dwarf planet.

Inner Planets vs. Outer Planets More closely spaced Terrestrial planets- small, dense, and rocky Mercury, Venus, Earth, and Mars Spaced farther apart Gas giants- larger and made mostly of gases Jupiter, Saturn, Uranus, and Neptune
