If a scientist needs to investigate something, such as say, a murder crime scene (like on TV) or a sick animal somewhere, they need to decide which tools to use, to best figure out the problem. They also need to figure out an order of jobs they need to do, to inspect said problem. Finally, they need to use safety precautions, because they don't want anyone to get hurt. This could include cutting something in a way that will avoid injuring themselves, and so on. Hope I could help! :)
