Could someone explain independent, dependent, and noun clauses for me?

you!

 An independent clause is exactly what it sounds like. It's a group of words that can stand on its own as a sentence: it has a subject, a verb, and is a complete thought. Examples: He ran.

An dependent is the opposite. A  group of words that also contains a subject and a verb, but it is not a complete thought

Noun clauses is a dependent clause that acts as a noun. 

An independent clause is a clause that can stand alone as a sentence (it expresses a complete thought). An independent clause, like all clauses, has a subject and verb. For example: The best defense against a atomic bomb is not to be there when it goes off.

A dependent clause (or subordinate clause) is one that cannot stand alone as a complete sentence because it does not express a complete thought. For example: The crew could see the whale, which had surfaced only 50m behind them.

A noun clause is a clause that plays the role of a noun. For example: I've met the man who won the lottery.
