| 1. Why do science fair projects usually work out better when you use the scientific method? | |
|
Answer: When you use the scientific method, you can share with others what you learned from research, not just demonstrate a science principle that you read about in your science book.
|
|
| 2. If you use the scientific method, and you prove that your hypothesis is wrong, have you failed? | |
|
Answer: Not really. Any time you can prove a hypothesis, whether it is right or wrong, you have still succeeded because you know something you didn't before.
|
|
| 3. What would happen if you wanted to know something using the scientific method, but you left out the step of experimentation? | |
|
Answer: Without experimentation, you would not have any evidence to prove or disprove your hypothesis. You could not find a valid answer to your question.

| 4. Choose any of the four gravity experiments Galileo performed, and use the steps of the scientific method to summarize the experiment. | |
|
Answer: 1. Ask a question – Do objects fall at the same rate?
2. Study the question – it was commonly believed that objects fall at different rates
3. Form a hypothesis – objects fall at different rates based on their weight
4. Experiment – drop two items of different weight at the same time to measure which one hits the ground first
5. Evaluate the results – the two objects landed at the same time. The hypothesis is invalid.
