We started this week with a discussion of what happens in a star. This is because it involves density, force and motion, and our new subject, matter. Now add to this conversation, by finding out if the same thing happens in bigger and smaller stars. Find out what kinds of stars their are. Tell me about what kinds of forces I didn't talk about that happen in a star. How about some details on how fusion creates the different types of atoms in a star? Add to what we know!

their is the Proto star, T Tauri Star, Main sequence star,Red Giant

Good list to start from, but what does this mean? Give us something more than names for some real extra credit! Remember, no cut and paste. Anyone want to help?

Protostar- is made up of gas that went apart from its molecular cloud. Over time passes, gravity and pressure rises up, which makes the star collapse. The energy falling out of the star only comes out when the heating foes nears the star caused by the gravitational energy.

Stars are formed out of clouds cool,dense,moleculor gas. To become a strong potential star, the clouds need to collapse and increase in density.

Can someone tell me what these molecular clouds are? You actually know already, but I want someone to connect them.

Um i can try to say what they are :D. I know that the clouds are made up of Atomic Hydrogen and Helium. If i'm right, Molecular Clouds are clumpy and I guess basically gas. :D I tryed.

Proto star is a large mass that forms by tightening out of gas of a giant molecular cloud in the interstellar medium.

Proto star is a large mass that forms by contraction out of gas of a giant molecular cloud in the interstellar medium.

OK Giovanni nice start at defining, but I've never heard 8th graders talk like this! Can someone rework Gio's definitions into something that makes sense to all of us? Translate those words!

Stars are powered by nuclear fusion in their cores, mostly converting hydrogen into helium.

Great Contribution John! This information is helpful to me too. ... And thanks for not taking credit for someone's work!

Protostar- A protostar is formed by contraction of gas of a very massive molecular cloud.

Nice work Hickman! This is really good. Did you come up with all of this on your own, or did you use a resource? Post what resources you might have used. Comments are closed.
