What is a thesis? Please answer it d u mb enough for an elementary student to understand. thank you

A thesis statement declares what you believe and what you intend to prove. A good thesis statement makes the difference between a thoughtful research project and a simple retelling of facts.

Explanation:

A good tentative thesis will help you focus your search for information. But don't rush! You must do a lot of background reading before you know enough about a subject to identify key or essential questions. You may not know how you stand on an issue until you have examined the evidence. You will likely begin your research with a working, preliminary or tentative thesis which you will continue to refine until you are certain of where the evidence leads. The thesis statement is typically located at the end of your opening paragraph.
