And start working on it.
OBJECTIVES & LEARNING GOALS:
ASTRONOMERS CAN:
• Recall important information about the
Earth-Sun-Moon system and how it
causes Seasons, the Lunar Cycle, and
Tides in order to prepare for our End of
Course Exam (May 18-20).
Such as
The SUN
The center of
Our Solar System
The Earth is part of our Solar
system which is on an outer
arm of the Milky Way galaxy
that contains billions of stars.
The Universe contains billions
of galaxies that can be spiral,
elliptical, or irregular.
The sun is MUCH CLOSER to us
compared to all other stars. Therefore it
looks much brighter even though it’s not
compared to other stars.
The milky way has billions of stars that
orbit around the galactic bulge center.
The solar system has 8 planets and
billions of other objects that orbit around
the Sun.
Where do we fit in??

The Sun’s powerful gravity holds all This law explains the formation of the
of the objects listed in their orbits. Solar system and orbital movement of
objects around the Sun.
Historical models eventually built
up to this idea.
The surface would be rocky on a
terrestrial planet and gaseous on a
gas giant planet with no real surface
to actually land on
Energy is transferred from the SUN’s
core upwards by radiation. Then,
convection transfers the energy to the
surface. It can take over a million years
for 1 cycle of this to occur!!!
The positions of the Earth, Sun, and
Moon and how they change daily with
respect to one another. The amount of
light coming from the Sun stays the
same.
1. The moons phases are caused by the
alignment of the Earth, Sun, and Moon
which changes daily as the moon
revolves around the Earth. Lunar
eclipses occur when Earth’s shadow is
cast on the moon.
3. During June Solstice, Earth tilts
toward Sun giving the Northern
hemisphere more direct sunlight and
warmer temps while Southern
Hemisphere has opposite. During
December Solstice, Earth tilts away
from Sun having the opposite effect.
2. Even though the Sun is much larger
with stronger gravity the moon is MUCH
4. It takes the moon the same amount
CLOSER to Earth causing it to have a
of time to rotate as it does to make one
greater effect on tides.

I remember this information very well.
I remember most of this information and only need to review a little.
I remember a little over half of the information. I do need to review some
of what I missed.
I remember very little of this. I got a few questions right but I mostly
guessed. I really need to go back and study.
I don’t remember any of this information. I missed almost all of the
questions I answered today and I really need to review this information.
