Before you open the simulation:
PREDICT
1. Draw a diagram below showing what you think the molecules
will look like for each state of matter, solid, liquid, and gas. Write a
sentence below each diagram predicting what the motion of the molecules will be
like.

Sentence explaining how molecules will
be moving.
|
The molecules will be moving slowly in
and there will be very little space in-between them.
|
The molecules will be moving more
quickly but there is still a certain
amount of space between the molecules.
|
The molecules will move more freely
and there isn’t a certain amount of space between the molecules.
|
2. If you start with a substance as a solid, what will
happen to the molecules as you add thermal energy (heat)? They will slowly start to come apart from one
another, because the solid is now turning from its solid state to a liquid
state.
ONCE YOU HAVE
COMPLETED THIS PAGE, YOU MAY BEGIN THE SIMULATION.
Open the simulation. You will find it in a folder on your desktop labeled “States of Matter Simulation.”

INVESTIGATE:
3. Use the menu on the right side of the program to select
Water and Solid. Draw and describe what you see in the space below.
|
Diagram
|
Description
|
 |
All of the molecules are moving back
and forth in a small space they are very close to one another
|
4. Now, use the slider on the bottom of the program to Add
Heat. Notice the thermometer at the top of the program. What temperature scale
is this thermometer showing? It
shows fire.
5. What happens to the water as you increase the
temperature? The molecules
start to go crazy at first they bunch really close together. Then they just
start to scatter.
6. What is the melting/freezing point of water in Kelvin? Melting/Freezing point of water is 273.15 K
7. Add heat until the temperature is just below and then
just above the melting point of water. How is water different below its melting
point and above it? Below it stays
close together and they bounce off of each other. Above the molecules get even
closer than below .
8. Draw and describe what water looks like as a liquid.
|
Diagram
|
Description
|
 |
The molecules are very close together
and they seem to be really close to one another. They stay together also in
the same clump.
|
9. What is the boiling/condensation point of water in
Kelvin? The boiling/condensation
point of water is 373K.
10. Continue to add heat until you are just below and then
just above the boiling point of water. How is water different below its boiling
point and above it? They
start to separate below it. And above its boiling point it they are moving
quickly and bounce all around.
11. Draw and describe what water looks like as a gas.
|
Diagram
|
Description
|
 |
The molecules are bouncing off the
walls and have a lot of space between them.
|
12. Choose one of the other three substances listed in the
menu on the right. Investigate what happens when you add and remove heat from
this substance. Use the buttons on the right to see this substance as a solid,
liquid, and gas. Draw and describe its properties in the table below.
Substance Selected: Neon

Sentence explaining how molecules are
moving.
|
The molecules are tight almost in the
shape of a square.
|
The molecules have a little more space
and some seem to go away from the pack.
|
There is a lot of space between the
molecules and they are bouncing off the walls.
|
ANALYZE:
13. How was this substance similar to water in each state of
matter? How was it different? In
both substances the solid state the molecules were tighter together. In the
liquid state they started to move away but were still close. And in the gas state both sets of molecules
were scattered all around.
4. Were your predictions (see p. 1) correct or incorrect?
Explain. Yes, I thought
the solid state the molecules were tight together, the liquid state the
molecules starts to separate, and the gas state the molecules were much farther
apart.
BONUS: Optional,
worth up to 10 points added to the lab’s final grade
15. Choose a substance other than water from the menu on the
right side of the program. Use the slider to add and remove heat. Based on what
the molecules do, figure out the approximate temperatures of the melting point
and boiling point of this substance. (Hint: The temperatures given when you
click solid, liquid, and gas are NOT the melting and boiling points.)
Substance: Oxygen
Melting Point: -361.8°F or 54K
How did you figure it out? By looking at the molecules and seeing the reaction to the
cool. They got as close as possible.
Boiling Point: about
90.188K
How did you figure it out? The way in which the molecules move when I adjust the
temperature.
3.
They are attached to one another and it looks like
they are magnetized. They are not even moving because it’s down to zero. Most of the hydrogen atoms are attracted to
the oxygen atoms.
4.
The temperature is 50 K and the pressure is .06
atm
5.
The science standards that I felt most
corresponded to Standard A 4.2 when face with a science-related problem, decide
what evidence, models, or explanations previously studied can be used to better
understand what is happening now.
Standard C 4.2 use the science content being learned to ask questions,
plan investigations, make observations, make predictions, and offer
explanations. Also C 4.5 use data they have collected to develop explanations
and answer questions generated by investigations.
