An example of an investigatory project in science is using a thermometer to measure the air temperature of different places. The investigator starts by going in the shade of a tree, holding a thermometer 4 feet from the ground and recording the reading on a piece of paper. Next, the thermometer is held 1 foot from the ground while still in the shade.
The investigator then steps out of the shade and into direct sunlight. Here, the readings are different. Windy day temperatures may also be recorded. This investigation helps students to understand the different factors that affect air temperature.
Another example of an investigatory project is making soap out of guava leaves. A person may be looking for a solution for people living in remote areas without access to soap. The problem pushes a science student to seek real solutions from locally available materials. This project creates soap from a mixture of sodium hydroxide and guava leaf extract. The soap produced from the procedure can be used for washing and bathing.
Investigatory projects are scientific assignments that students conduct to seek an appropriate solution to a problem. Before embarking on the study, a hypothesis should be formulated on what the study’s outcome would be. However, the expected outcome may not always be witnessed.
