Well, scientists depend on science.They use the process of observation. But there are processes for these. The processes are; Asking a question; Scientists wonder how specific happenings can be explained, they look for an answer. They perform research; the scientists study the particular thing, and look for reasons for a particular happening. They form a hypothesis; a hypothesis is a statement which is not universally true, they are observations that haven't been agreed upon. They test their hypothesis; they perform experiments to find out if their hypothesis is true. They analyse the data and draw a conclusion; they record their hypothesis and write down their end result. They pass across their result; they pass their new observation across to other people. Hope i helped. Have a nice day.
