Doing Science


Steps in doing science

            Ask a question

            Look it up

            Frame a hypothesis

            Design experiment to test hypothesis

            Carry out experiment

            Draw conclusion


It is easier to test one hypothesis at a time

            Make operational definitions

            Control variables


Hypotheses must be testable

            It is not a test if you cannot fail it


We don't prove things in science because we cannot test all possibilities

            Science relies on samples and sampling

            Everything in science is tentative
