States Of Matter
Title: States of Matter
Introductions:
In this activity you will investigate the physical science of the different states of matter. You are going to see how different atoms and molecules (types of particles) change state (solid, liquid, and gas) when they are heated or cooled.

2. Click the “Play with sims” button.
3. Click “New Sims”->Click “States of Matter: Basics”->Click “Run Now”
This is a screen shot of the simulation once loaded:
4. Switch between this document and the simulation “States of Matter: Basics” to complete this activity.
Exploration Phase:
1. When you open the sim, click the “Solid, Liquid, Gas” on the upper left hand corner.
2. On the right hand side, you will notice that there are different atoms and molecules (types of particles) for you to explore with. There is neon, argon, oxygen, and water.
3. First click the “neon” button and increase the heat and observe what happens to the particles. Then decrease the heat and observe what happens to the particles. Observe the temperature as well.
4. Repeat step 3 for the argon, oxygen, and then water.
Questions:
1. A.What did the neon particles do when the pot was heated?
They started vibrating, translating, and rotating faster. They started to gain more kinetic energy (
B. How about when the pot was cooled?
They started to vibrate, translate, and rotate slower. They reduced their kinetic energy until they weren’t moving at all
2. Do you think the neon particles changed their state? (i.e. did it change to solid, liquid, or gas?) How can you tell?
They changed from solid to liquid to gas
3. When the neon particles were cooled again, did they go back to it’s original square formation? Why do you think it did/did not?
Nope, this is because when they had kinetic energy, they moved around a lot.
4. Are the argon, oxygen, and water particles similar to the neon particles? Why/why not?
Yes because
