This is a short explanation of what a hypothesis is and the five things that make a good hypothesis:
-It's written as a statement, not a question.
-It predicts how the experiment will turn out.
-It is testable.
-It is based on what you already know.
-It explains the relationships between the variables and why you think the results will turn out a particular way.
It also gives an example of what a good hypothesis looks like, using an "if-then" statement.
