Abstract-Limit the abstract to four to five sentences stating the following: (a) statement of the problem, (b) methodology, (c) pertinent results, and (d) conclusion. Avoid numbers and symbols in the abstract. After you have written the abstract, write the title. In not more than 13 words, choose a title that would reflect your abstract. To do this you may use the “variable-method” structure, e.g. “Measuring a car’s acceleration using a pendulum.” Here the variable is the gravitational acceleration and the method is the simple pendulum. Another way is to use the “dependent-independent variable” structure, e.g. “Angular displacement of a pendulum in an accelerating car.” Here the dependent variable is the angular displacement of a pendulum and the dependent variable is the car’s acceleration. Note: do not mention any keyword in the title that you will never discuss in your report. A title is a promise that you must keep. (9)
The main purpose of the introduction is to give a motivation for the problem in the laboratory experiment performed. There are many ways to do this. One way is to start with mention something familiar to your reader, then slowly lead him to something unfamiliar—your problem. Along the way, define the terms in the title starting from the subject to the modifiers. Let us give an example. Suppose your title is “Measuring a car’s acceleration using a pendulum.” Notice that the structure of the title is “variable-method.” Because “car” is the most familiar, begin with “car” and relate it with “acceleration”: describe what pedal to press, what then happens to your car, and end with a note that this is acceleration. Then define “acceleration” precisely. You have just finished explaining the variable part of your title and
