Question

A scientist decides to study the effect of salt on a particular type of bacteria. Arrange the steps of the scientific method in the correct order to show how the scientist would proceed with his work. The scientist asks the question, Does salt help the growth of these bacteria? The scientist puts the bacteria in three different environments: high salt, medium salt, and low salt. A microbiologist notices that some bacterial species thrive in salt water environments. The scientist forms a hypothesis that higher concentrations of salt may increase the growth of these types of bacteria. The scientist publishes his report in a scientific journal. The scientist finds that the high-salt environment has the most bacteria. ↓ ↓ ↓ ↓ ↓

Answer 1

The steps of the scientific method in studying the effect of salt on bacteria are: observation, question, hypothesis, experiment, data collection, analysis, conclusion, and publication.

Answer 2

To study the effect of salt on bacterial growth, the steps include observation, forming a question, hypothesizing, experimenting, and publishing the results. The observation that certain bacteria thrive in saltwater leads to an experiment with different salt concentrations and concludes with the scientist publishing their findings.

Step-by-step explanation:

To investigate the effect of salt on bacterial growth, the scientist should follow these steps in accordance with the scientific method which include making an observation, asking a question, forming a hypothesis, conducting an experiment, and publishing the findings:

An observation is made that some bacterial species thrive in saltwater environments.

The scientist asks the question, 'Does salt help the growth of these bacteria?'

A hypothesis is formed that higher concentrations of salt may increase the growth of these bacteria.

The scientist creates an experiment with bacteria in three different salt environments: high salt, medium salt, and low salt concentrations.

The experiment's results show that the high-salt environment has the most bacteria.

Finally, the scientist publishes the report in a scientific journal.

With the step of publishing results in a scientific journal, the process comes full circle, allowing other scientists to review, replicate, and extend the research.
