mc2.cchem.berkeley.edu/Java/molecules/index.htmlthis "applet" shows particles bouncing around. You probably won't understand all of the simulation, but it is fun to mess with the temp, mass and number of particles and see how the motion changes. This is an accurate idea of what gas particles probably look like, if we could see them, but liquid pariticles would be closer together. Some possible discussions: What limitations are there with this applet? Why did I not show you this until after we had learned about particles? How did this applet change your thinking/understanding of particles?

The higher temperature the faster the particles and the lower the temperature they slow down because they have less energy. So when they have high temp. they move alot faster

#2 you needed to make sure that everyone fully understood particles

2) Everyone needs to have a good understanding of the particles to understand this.

i liked it. it shows you how they move when you increase or decrease one of the variables.
that and it was just fun to mess around with it.

that was amaxing Mr. Kruse!! i think you didn't show us that because we would have to understand why they moved the way they did. and about density

So that we would understand why it moved so fast or slow and why they are bigger and smaller

Thats was kool. lolz
i understand that.
i guess

You had to show us this after we learned about particles because we probably would think that the particles are that size when they are really much smaller than that.

So the colder it is the slower particles would move but what if was both hot and cold

I though particles would move slower when hotter. But that helped me understand it better.

Well, I think that there are MANY, MANY limitations with that application. They limited the temp., number of particles, and other stuff like that.

Well, I think that there are MANY, MANY limitations with that application. They limited the temp., number of particles, and other stuff like that. Another limitation is that if the particles moved at their actual speed, they would be moving a lot faster. Also, the particles on screen can't move in three dimensions. |
