2. Agenda!
States of Matter
1) Warm-up
2) Set up Notes
3) Accessing Prior Knowledge: What do you already
know?
4) Notebook Activities
5) Lab
6) Pass out HW
3. Warm-up!
Water is a unique substance because it is weighs less
when it is a solid than when it is a liquid. What
would happen if ice was heavier than liquid water?
How would the world be different?
4. Set up your notebook
On the next blank page, set up your Cornell notes
and write these 2 focus questions:
Topic: States of Matter
Objective: Students can describe molecules in solids,
liquids, and gases
1) What do molecules look like in solids, liquids,
and gases?
2) If we could see these molecules with a
microscope, what would we see them doing?
5. Notebook Activity #1
In your Cornell notes, write as many things you
know about solids, liquids, and gases. Mr. Lee will
select some students to write on the whiteboard.
6. Notebook Activity #2
Today we will learn about “molecular arrangement”,
“molecular attraction,” and “molecular movement.”
What do you think this means? Discuss with your
elbow partner
In your Cornell notes, write 2 sentences on how you
think the molecular arrangement and molecular
movement are different for solids, liquids, and gases.
7. Activity #3
On the next page after your Cornell notes, Draw 3
objects: something that's a solid, something that's a
liquid, and something that's a gas. For example:
glasses, gatorade, and a cloud.
Look at Mr. Lee's example
11. On the three pictures that you drew, draw what the
atoms would look like inside your object. Are they
close together? Far apart? Look at Mr. Lee's
demonstration for an example
12. Notebook Activity #4
Read the worksheet and write the differences
between solids, liquids, and gases. Draw a picture at
the bottom.
13. Answer Focus Question 1
We will now answer the focus question as a class.
Mr. Lee will select one student to state the answer to
focus question #1.
14. Focus Question 2
Now that you've learned how
the molecules are arranged, and
that molecules are all attracted
to each other, we'll ask what
they're doing. If we had a
microscope powerful enough,
we would see that these
molecules are moving. How
would this molecular movement
be different in solids, liquids,
and gases?
15. Cornell Notes: copy
Question: Is the speed of molecules higher in hot and
cold water?
Hypothesis: ___________________
Experiment Design: test the mixing of food color in
cold and hot water
16. Read Procedure
Read the directions as a class and answer the 6
questions at the end of the directions sheet to receive
your materials
17. Final notes!
Molecules move faster in hot water than cold water.
If water gets hot enough, molecules will move fast
enough to overcome their attraction and become a
gas. If water gets colder and colder, molecules will
slow down and eventually stop, forming a solid.
18. Answer Focus Question 2
How is the movement of molecules different for
solids, liquids, and gases?
19. Next week:
Tuesday we'll look at solids at the microscopic level an
see that they have a crystal shape.
