Explanation:

Environmental science can be defined as an interdisciplinary field of science that comprises of chemistry, economics, engineering, zoology, geography, geology, biology, ecology, physics, etc., used for the study and understanding of various environmental factors, issues in relation to human life.

All of the laboratory tools such as conical flasks, microscope etc shown in the attached image are used by scientists, biochemists, and laboratory technologists, for conducting an experiment.

An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).

This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
