hypothesis/prediction
Well, first of all, observations about the water need to made. Then, a hypothesis needs to be formed from the observations. Hypotheses should follow the "if, then" format. Ex. If toxins are present in the water, then fish will die. It's just following the scientific method.
Scientists use the scientific method, which involves forming a hypothesis, designing and conducting experiments to test the hypothesis, analyzing the data collected, and drawing conclusions based on the results. This process allows them to gather evidence and make informed decisions about the question they are trying to answer.
The independent variable is purposely changed in an experiment to test a hypothesis. This variable is manipulated by the researcher to observe its effect on the dependent variable and determine if there is a cause-and-effect relationship.
After making a hypothesis, the next step in the scientific method is to conduct an experiment to test the hypothesis. This involves collecting data and analyzing results to determine if the hypothesis is supported or refuted.
A hypothesis states a predicted outcome for an experiment, while an experiment is designed to test the validity of the hypothesis by collecting data and analyzing results. The experiment provides empirical evidence to either support or refute the hypothesis. The relationship between hypothesis and experiment is crucial in the scientific method for forming and testing ideas.

Scientific Method
Scientists test hypothesis by setting up an experiment. They choose a independent and a dependent variable and test the experiment.
scientists test their hypothesis buy making observations or doing research
scientists test their hypothesis buy making observations or doing research
Scientists then state another hypothesis and test it out with another experiment.
In a lab or wherever they can conduct an experiment
Test
if your referring to the scientific method, scientists test the dependent variable
...perform a scientific experiment designed to shed light on the hypothesis.
