How to Write a Scientific Report Introduction

Updated July 20, 2017

Scientific reports present experimental data and conclusions that convince or dissuade others of the preliminary hypothesis. Sometimes reports are recorded for future scientists and researchers. To write a scientific report introduction, you must thoroughly conceptualise and present the main purpose and objective behind the research. With the background presented, the reader should clearly understand the rest of the report just by reading the introduction. The introduction is like the first impression you present to someone, whether it be a researcher, member of the media or your teacher, so writing a strong one is imperative to the ultimate message and conclusion.

State the purpose or purposes of the experiment, maintaining a clear distinction between your hypothesis and your purpose.

Write a clear hypothesis or educated guess that defines each variable and the expected reaction. Most hypotheses contain two variables, an independent and a dependent variable. The independent variable is used to test the reaction and the dependent variable changes depending on the reaction.

Justify the hypothesis based on scientific evidence or data.

Tip

Ask questions about the hypothesis and parallel it with the conclusion. Asking yourself questions will help you see the "big picture," which will in turn help you integrate a synopsis successfully into the intro.

Warning

The background of the intro should completely focus on the experiment; do not go into tangents of other data recorded or details. Write background or previous research with your audience in mind. Your general background research would be very different if you were writing for an instructor as opposed to a medical journal.
