Hint on how to write a hypothesis

Guess the answer to a testable question about an observation you make.

Explanation:

Making and testing hypotheses is an essential part of the scientific process. A hypothesis is simply an educated response to a question based on something you observe. For a simple example, say you try to turn you lamp on when you wake up in the morning, but nothing happens! Clearly, something's happening here. Based on the observation ("My lamp isn't turning on!") you can ask yourself a question ("Why isn't my lamp turning on?") which you can answer with a hypothesis ("I think the lightbulb is burnt out.")

The important part is that our hypothesis is testable: we can set up an experiment to gather evidence for or against it. To see if we're right about the lightbulb, we can test the hypothesis by plugging something else into the same outlet. If it turns on, we know it's probably something specific to the lamp! If not, we have a new observation ("This other thing won't turn on either!") that we can use to ask a new question, ("Why won't either of these things turn on?") update our hypothesis, ("Maybe it's an issue with the outlet!") and test that hypothesis ("I should try plugging them into a different outlet and see if they turn on then.")
