Reports are what 6th graders write about Oliver Twist, but we want to do more than just report. In almost any college level paper, you will want to be analytical. That is, you will want to present the facts you have found, and then interpret them for your reader using the experience you have gained from your own reading and from your work in the course. Thus you might report on evidence for volcanism on Mars and then analyze this evidence to show that some of it is open to question and some is not. Remember to analyze your subject.
Papers can sometimes describe procedures such as laboratory projects and their results.
Of course, you must report on the methods you employed, but you must then analyze your results. And so on. Answering such questions is a form of analysis common to good laboratory papers. The three secrets to success in writing are Organization, Organization, Organization. You must arrange facts and the relations between facts in a meaningful order.
