Crafting Testable Questions in Scientific Inquiry

The video tutorial explains how to write a testable question, which is a question with a specific answer that can be found through investigation. It distinguishes testable questions from opinions and questions that can be answered by looking up information. The tutorial describes different types of testable questions, including descriptive, comparative, and experimental questions, and provides examples of each. Finally, it presents a test question for viewers to consider before proceeding.
