Testable Questions in Science: Distinguishing Facts from Opinions

The video tutorial introduces the concept of testable and non-testable questions in science, comparing scientists to detectives who ask good questions and solve problems. It explains that testable questions can be answered through experiments and data collection, while non-testable questions often involve opinions. Examples are provided using paper airplanes and chocolate to illustrate the difference. The tutorial concludes by encouraging students to practice identifying testable questions and prepare for future experiments.
