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
• Spaced farther
apart
• Terrestrial planetssmall, dense, and
rocky
• Gas giants- larger
and made mostly of
gases
• Mercury, Venus,
Earth, and Mars
• Jupiter, Saturn,
Uranus, and
Neptune
