1. In the example below, the scientific method is used to solve an everyday problem. Order the
scientific method steps (numbered items) with the process of solving the everyday problem
(lettered items). Based on the results of the experiment, is the hypothesis correct? If it is
incorrect, propose some alternative hypotheses.
1. Observation: C. My toaster doesn’t toast my bread.
