Teaching how to write a hypothesis may be one of the trickiest components to teaching students about science. Ultimately, the most important phase of writing a hypothesis is not the actual putting together the sentence that becomes the hypothesis, but determining the testability of a question based on an observation that was made. The question that leads to the hypothesis must be testable and this can be a very discouraging step in the process. In order to write the question and ultimately make the hypothesis, the student must have a clear idea of what was occurring and from that clear idea must have a thought as to why the phenomenon might have occurred. This is can even be a daunting task for well-trained scientists.
This PowerPoint presentation introduces students to the concepts of a hypothesis and goes hand-in-hand with the lesson "Writing a Hypothesis"
