Answer:

The scientists are conducting an investigation.

Explanation:

According to the question, a group of students want to know the quality of water in the drinking fountain and thus they conduct several tests which include checking the mineral content, pH, density and clarity of the water.

The best explanation of the student's plans is that they are conducting an investigation.

An investigation is when a person conducts a test to find out something or to make an obscure thing clearer.

The students are NOT conducting a controlled experiment because their tests were not done in controlled conditions where some variables were changed at a time and others were kept at constant.
