CONNECTION BETWEEN HYPOTHESIS AND EXPERIMENT Hypothesis is a critical part of experiment design Translation I have an idea and want to see if it is valid Consequence: My experiment is designed so it can achieve this No experiment should be undertaken without a clear preconception of the form its results might take Advice to a Young Scientist [sir Peter Medawar The experiment is being carried out to assess the hypothesis, not to rove it Examine engineering evidence critically One school of thought is that the most critical scrutiny should be when experiment and hy pothesis agree The strength of your conviction about an idea has no bearing at all on whether it is true or not-and vice versa"Medawar]

AN ACTIVE LEARNING EXERCISE For your project, with your partner, write down(or commit to memory) a short description of your project and what you think the Hypothesis is(Hypotheses are) I will ask groups to report on what they wrote You will get more chances to hone the H (and Os) An experimental observation is that a good HOS is a requisite( even a blueprint) for success in this subject
