A Science Investigatory Project (SIP) is a science-based research project or study that is performed by school children. It is usually a science experiment performed in a classroom setting with the class separated into small groups, but can also form part of a scientific exhibition or fair project. The main aim of a SIP is to provide school-aged children with an engaging way to learn more about science and the concept of performing scientific research. The approaches used are often broadly aligned with those used by PhD students carrying out a research project. The structure and procedure of a SIP are similar to that for a serious research study, but it is meant to be “light” and fun compared with a research project at a higher level. The scientific method is used to study and test an idea about how something works. It involves researching a topic, formulating a working theory (or hypothesis) that can be tested, conducting the experiment, and recording and reporting the results. SIPs have applications in the social sciences as well as in physical sciences such as chemistry, biology, astronomy, geology, and medicine. They provide students practical experience in scientific research and can serve as a gateway to a career in the sciences.
