a. There is something wrong with the electrical outlet.b. If something is wrong with the outlet, my coffeemaker also won’t work when plugged into it.c. My toaster doesn’t toast my bread.d. I plug my coffee maker into the outlet.e. My coffeemaker works.f. Why doesn’t my toaster work?
In the example below, the scientific method is used to solve an everyday problem. 1. Order the scientific method steps (numbered items) with the process of solving the everyday problem (lettered items). 2. Based on the results of the experiment, is the hypothesis correct? 3. If it is incorrect, propose some alternative hypotheses.
1. Correct order: C; 2: F; 3: A; 4: B; 5: D; 6: E.
2. The original hypothesis is incorrect, as the coffeemaker works when plugged into the outlet.
3. Alternative hypotheses include that the toaster might be broken or that the toaster wasn't turned on.
