Science Log 7
Monday, November 28:
If you were a cosmologist (someone who
studies the cosmos), what part would you
focus your studies on? Why?
7.2 Origins
Focus Question 7.2, put on page 82
The cosmos is the largest structure studied by
scientists.
As we learned, the Hubble Space Telescope has
provided images of galaxies that are billions of
light-years away.
Scientists who study the cosmos are called
cosmologists. Cosmologists study the structure of
the cosmos and try to figure out its history and
future.
7.2 Origins
Focus Question 7.2, put on page 82
One of the most important questions
investigated by cosmologists is how things
came to be the way they are.
Where did the objects we see today come
from?
A cosmology question they would investigate
is
Where did the solar system come from?
2. Solar system questions
You are going to work like cosmologists in your
groups
Generate a list of questions that might help you
figure out how the solar system came into
being, from a scientific point of view.
Be ready to share
2. Solar system questions: Might include
What was here before the solar system?
Where did the planets and moons come from?
 What are planets and moons made of?
Where did the Sun come from?
Are there other solar systems like ours?
Is there life in other places in the solar system?
Did the solar system come from the big bang?
Vocab 7.2
Record on page 80 and in your index, use the
card to add to the definitions in your own
words
Nebula: Cloud
Accretion: Sticking together
4. Solar system Origin cards
 Solar System Origin cards.
 Each set represents one possible step in the sequence of
events that resulted in the solar system.
 You should work at your tables to put the stages of formation
in order
 Spread the cards out so that they can be seen by everyone.
 The text on the backs of the cards adds information to the
pictures.
 You have 10 minutes
6. Formation sequence
Notebook Sheet 40, Formation of the Solar
System
Record the names under the “predicted
sequence” column
Tape into page 83
7. Sequence
What do you think occurred first?
What is your reasoning?
“Solar System Origin Card Sort”
7. Sequence
What do you think occurred first?
What is your reasoning?
“Solar System Origin Card Sort”
Nebula is first
Record the sequence under the current
theory
9. Summarize solar system formation
Look at the current theory you recorded on
your Formation of the Solar System sheets.
Underneath the focus question, explain, as if
you are telling a story, how the solar system
formed.
That means, don’t just list the ten steps, but see
if you can describe the steps, from start to finish,
to a friend or younger sibling who has never
seen the cards we used today.
10. Quick draw
Confirm your features of the system you
represented well, correct features you want to
revise, and complete your representations by
adding features you overlooked originally.
Write a summary statement that reflects on
what you originally thought and what you now
think, giving specific examples from your
original thoughts and from what you have
learned.
