30	What do scientists do when they DRAW CONCLUSIONS?
31	What do scientists do when they DRAW CONCLUSIONS? Answer the original question State whether or not the hypothesis was supported (it is never “right” or “wrong”) Pose questions for further research
32	Define HYPOTHESIS
33	Define HYPOTHESIS A statement that can be tested by conducting an experiment Prior knowledge, new information, observations can be used to form a hypothesis
34	Why are REPEATED TRIALS necessary in an experiment?
35	Why are REPEATED TRIALS necessary in an experiment? To make sure results are valid The more trials conducted, the more likely the results are reliable To make sure a “fluke” is not considered the true result
