States of Matter: The particle model

Name:______Date: ______Core: ______

LT: I can use the particle model of the States of Matter to make inferences about molecular motion in the layers of the atmosphere.

Directions:1. Go to Internet Explorer. 2. Enter website: .3 Download simulation; 4. Click to open; 5. Choose “states”

Now: Take 5 minutes to freely explore the simulation.- Once you are done exploring, press the orange reset button to begin.

1.Under the Atoms and Molecules section, click on Oxygen.
2.Above the thermometer, use the arrow to select the temperature in Celsius.
3.On the right hand side, click on solid. Observe how the oxygen molecules are moving at this temperature. Draw a picture of what you see & describe how the molecules are moving.
4.Continue to do the same for liquid and gas. Draw and describe how the oxygen molecules are moving in each state. /

How does molecule movement change?

In the table below, draw a picture AND describe the motion of OXYGEN molecules in each state

State of Matter / Draw a picture of all the molecules / Draw ONE molecule, and use arrows to show avg. movement / Describe the motion of the molecules
Solid
Liquid
Gas

What happens when molecules get heated up or cooled down?

  1. Under the Atoms and Molecules section on the right hand side, click on Water.
  2. On the right hand side, click on solid. Observe how the water molecules are moving at this temperature. Draw a picture of what you see & describe how the molecules are moving.
  3. Continue to do the same for liquid and gas. In the table below, draw and describe how the water molecules are moving in each state.

Temperature / Draw a picture of all the molecules / Draw ONE molecule, and use arrows to show avg. movement / Describe the motion of the molecules
Cool it down to -200 °C
Warm it up to
50 °C
Now warm it up more, to
400 °C

Put it together:

  1. Generalize: What happens to the movement of molecules at the temperature increases
  1. Make an inference: * Hint: look back at your graphing the atmosphere!
  1. What happens to air molecules as you go up higher in the troposphere?
  1. How do you know? Explain your reasoning.
