Final answer:
The scientific method consists of making observations, asking a question, conducting research, formulating a hypothesis, testing it through experiments, analyzing the data, and drawing conclusions. Incorrect hypotheses lead to new hypotheses and repeated testing.
Step-by-step explanation:
Steps of the Scientific Method in Order
When a scientist is studying the effect of salt on bacteria, they would use the scientific method to ensure their work is systematic and reliable. Below are the steps a scientist would take, arranged in the proper sequence:
- Make observations: Begin by observing the bacteria and noting the effects of different conditions on their growth.
- Identify a question: From these observations, the scientist formulates a question to investigate, such as 'How does salt concentration affect the growth of this bacteria?'
- Research: Before proceeding, the scientist reviews existing literature to understand what is already known about the bacteria and the influence of salt on bacterial growth.
- Formulate a hypothesis: Based on the research and observations, a hypothesis is developed, which is a testable prediction. For example, 'Increasing salt concentration will inhibit bacterial growth.'
- Test the hypothesis: This is where the actual experimentation takes place. The scientist would expose the bacteria to varying concentrations of salt and observe the results.
- Analyze the data: After the experiment is conducted, the data is analyzed to see if it supports the hypothesis.
- Draw conclusions: Based on the data gathered from the experiment, conclusions are drawn as to whether the hypothesis is supported or refuted.
- Report results: Finally, the findings are shared with the scientific community for review and further research.
If the hypothesis is incorrect, based on the experimental results, the scientist would propose alternative hypotheses and repeat the process.
