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.

Explanation:

The scientific method starts with making an observation, then asking a research question, forming a testable hypothesis, and finally conducting an experiment to test the hypothesis.

1. First, the scientist makes an initial observation about bacteria in salt water.
2. Next, they ask a focused question based on that observation.
3. Then, they form a hypothesis to answer the question.
4. Finally, they set up an experiment to test the hypothesis.

Answer:

1. A microbiologist notices that some bacterial species thrive in salt water environments.
2. The scientist asks the question, Does salt help the growth of these bacteria?
3. The scientist forms a hypothesis that higher concentrations of salt may increase the growth of these types of bacteria.
4. The scientist puts the bacteria in three different environments: high salt, medium salt, and low salt.
