Do wrinkled seed coats affect germination in peas?
Hypotheses are not proved nor disproved, though scientists often say they are. Results from an experiment either support or fail to support the hypothesis. Either outcome is good. It is just as important to know which drugs are effective in treating a disease as it is those that have no effect. An experiment tests one or several hypotheses. The more hypotheses, the more elaborate and complicated the experiment becomes, so it is best to construct a hypothesis that is simple and straightforward. Hypothesis should be phrased to show a cause and effect relationship. This is best done as an if-then statement. It is a direct and logical expression that can be easily translated into a computer program language. If peas have a wrinkled seed coat, then they will not germinate. The cause is the wrinkled seed coats of peas. The effect is no germination. Wrinkled seed coat is the independent variable and germination is the dependent variable. Thus, germination depends on if the seed coat is wrinkl
