Open up your notebook
to page – 81
Get your book from the
back and open it to page
76.
Attach this page to page
81 in your notebook
And start working on it.
OBJECTIVES & LEARNING GOALS:
ASTRONOMERS CAN:
• Recall important information about the
structure of our UNIVERSE in order to
prepare for our End of Course Exam (May
18-20).
Work on questions 3-4
with your partner
We will go over them so
be ready to share.
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??
Practice on your own.
1. Turn to pages 77-80.
2. Tear out these pages and staple them when the stapler
comes around.
3. Answer the questions independently and quietly.
4.
We will review and discuss the questions together.

I remember this information very well. I missed no more than 1 question
on today’s practice question set.
I remember most of this information and only missed a couple of
questions. I only need to review a little.
I remember a little over half of the information. I missed 4-5 questions. 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.
 Deadly space weather - Venus
Level 4
I can compare and contrast the four
major layers of the atmosphere
(troposphere, stratosphere,
mesosphere, and thermosphere) in
terms of temperature and pressure
and explain how they contribute to life
on Earth.
Level 3
•I can list the four layers of the
atmosphere, explain how
temperature and pressure
change in each layer, and
describe how it protects life
and insulates our planet.
Level 2
•I can list the layers of the
atmosphere and how they
protect life on our planet.
Level 1
With help I can explain how
the atmosphere protects our
planet.
