1. What is being tested? (the aim of the experiment). 2. What is being changed? (the chosen variable). 3. What is going to be kept the same? (controlled variables). 4. What is going to be measured? (the measured variable). In general, you should ask how will your experiment help the earth, mankind, or people to accomplish a task.

Inference
The foundation questions for evidence in an investigation typically include who, what, when, where, why, and how. These questions help establish the basic facts and circumstances surrounding the evidence being examined.
Scientific investigation is a systematic method in which scientists and researchers answers particular questions about the world around us. It consists of the following: an observation, a question or a problem, hypothesis, an experiment and a conclusion.
Who, what, when, where, and why?

(the measured variable). In general, you should ask how will your experiment help the earth, mankind, or people to accomplish a task.
The purpose of a scientific investigation is to answer a specific question or test a hypothesis by systematically collecting and analyzing data using a carefully designed experiment or observation. This process allows scientists to draw conclusions and gain a deeper understanding of the natural world.
To answer their questions
By experiment.

Thorough investigation
he developed the basis of asking questions about stuff in an experiment like the whole hypothesis (if, then, because) just to be in general.
To answer the questions, Who - What - When - Where - and How. It is not necessary to determine "why" because if a crime was committed it is immaterial to the investigation to determine the reason.
Yes, variables can affect the results of an experiment by introducing bias or influencing the outcome. It is important to identify and control for variables to ensure the reliability and validity of the experiment's results.
