Answer:

Develop a hypothesis

Explanation:

Scientific investigations usually begin with observations these are typically something that would catch the researcher’s attention.

<em>1.</em> for example, <em>noticing that all the animals along a stream or water source are ill .</em>

2. The scientist ran attempts to understand what’s causing the problem after formulating or asking a question

  • <em>What’s making them ill?</em>

3. Then, the scientist comes up with a hypothesis which is a testable explanation for the phenomenon or what’s occurring

  • <em>Maybe the water is contaminated </em>

<em />

4. A prediction of the outcome is usually made based on the hypothesis

  • If I give the animals different water they’ll regain their health

5...after which it is tested via an experiment.

  • <em>Replace the water sources and observe </em>

6.  The scientist then use the results to make new hypotheses or predict certain outcomes.

  • <em>Hypothesis supported: animals regain health</em>
  • <em>Hypothesis not supported: maybe it’s the food?</em>

<em />

<em />

<h3>Based on the outcome the scientist may repeat the process which is a normal part of these steps. The scientific method explored above is very repetitive.</h3>
