Possible Testable Questions: Science Exit Project

Possible Testable Questions: Science Exit Project

This is a list of TESTABLE QUESTIONS. Some of these questions are really good testable questions some, some are okay, and would be much more appropriate with modifications. This is meant to help you develop ideas for your own personal project. I may let you choose one of these questions if it is grade level appropriate, but you really should be looking to develop one of your own. Remember this is a very long project, therefore you must choose a question that is worthy of this kind of in depth study. It is imperative that you develop/ select something that is of interest to you. You must be able to explain your interest or I will make you think of a new question. REMEMBER YOU MUST BE ABLE TO IDENTIFY THE IV and DV in your proposal along with a paragraph what of you think you are going to do!
