Greetings!
What you need is a thesis statement which tells what your paper will be about and takes a position on the topic. For example, if you were writing about immigration policy in the U.S., you could say "Immigration is a hotly debated topic in recent years, but a close look at the issue will show that immigrants contribute a lot to American society, bringing cultural diversity, a ready labor force, and many other benefits to the country." Your essay would then go on to talk more about these benefits, as well as mentioning the arguments against an open immigration policy, and why those arguments are not correct.
You can use this or a different topic, but that is the basic formula: a thesis statement in the introduction, followed by paragraphs which support your thesis and arguments against it which you then refute. Your conclusion will then summarize the main points of your paper.
When you are researching your topic, use your school library's online database to find articles and books about the subject. Use these sources to support your argument, quoting from them and using whatever form of citation your teacher told you to use. Ask your instructor or a librarian for additional help with this if you need to. It's a little confusing at first, but you'll learn quickly!
I hope this helps you get started!
