Explain a time you would need to evaluate something in science.

To study if the reuse of industrial treated wastewater may adversely affect life in a river basin system

Explanation:

The process of evaluation in science enables us to understand a given phenomenon from the natural world. Scientists have a standardized-objective method to investigate how the natural world works. This scientific method consists of the following steps: 1- to observe a given phenomenon form the real world, 2- to ask one or more questions about this phenomenon, 3- to raise a working hypothesis in order to explain these questions, 4-to test the hypothesis by experimental and/or observational procedures, 5- to obtain the results and conclusions. In this case, the scientific method can help to understand the effects of the industrial treated water in the life of the river system, and these results could be used as a starting point to predict its effects on other aquatic ecosystems.
