Conducting a Science Fair Project
Whatever the topic you choose, it must be one that you can experiment with yourself. A good way to start is to ask a question that can be answered only be experimenting. Here are some examples of topics chosen by other students and why they can or cannot be selected as good topics:
POOR TOPIC: "Motors"
The topic is too general. If the student is planning to describe how motors work, then he is merely doing a demonstration and not experimentation.
POOR TOPIC: "How Volcanoes Erupt"
This topic will not allow experimentation without visiting real volcanoes. If the student plans to make a model that erupts, then he is doing a demonstration and not experimentation.
GOOD TOPIC: "The Effect of Chemical Fertilizers On Bean Plants"
This could be a good topic because it suggests experimentation. The student must use a good scientific method in completing the project.
GOOD TOPIC: "How Do Pill Bugs React To Various Surfaces?"
This, too, could be a good topic because it suggests the use of an experimental method. The title of the project is in the form of a question. Asking a question is a good approach toward developing your topic.
