| Question | Answer |
|---|---|
| What are the 6 steps of scientific method | 1. Problem/Question 2. Research/Background 3. Form Hypothesis 4. Test Hypothesis 5. Analysis 6. Conclusion |
| Name & explain the 1st step of the scientific method | Problem/Question~ identify the problem |
| Name & explain the 2nd step of the scientific method | Research/Background~ research topic, materials, and past experiments. Find information on the internet, in books & magazines, and talk to experts |
| Name & explain the 3rd step of the scientific method | Form Hypothesis~ answer the question. Hypothesis~ educated guess |
| Name & explain the 4th step of the scientific method | Test Hypothesis~ 1. develop and experiment~ get all tools necessary 2. follow procedure 3. state observations & data |
| Name & explain the 5th step of the scientific method | Analysis~ make inferences |
| Name & explain the 6th step of the scientific method & tell why each step is important | Conclusion~ 1. accept or reject hypothesis~ states answer to problem. 2. Strengths and Weaknesses~ people can copy or change things 3. suggest further research~ tell other people what to do 4. report results~ give summary of report |
