Testing the Hypotheses
This is what separates science and faith. By testing the multiple hypotheses proposed for a question, they are accepted or rejected. The tests are repeatable, meaning other people can take the accepted hypothesis and test it independently. Current science theories are based on this principle, which means theories can and do change over time. How Betsy tests her hypotheses... Betsy decides to try a jumping experiment to see if the shadow is a part of her. She figures the shadow should remain connected if it is a part of her. To see if the shadow is a natural clock, or if the shadow is the result of the absence of light, Betsy decides to use an overhead lamp to look for a shadow at night. |
