Your Science Fair Project - Step 1 - Picking the Right Kind of Experiment
Science fair projects allow students to show off their talent and imagination, making it an exciting highlight of the school year. But for many students, one of the most difficult steps is just getting started. Before you can plan your project, and even before you pick a topic, you must first understand the different types of science fair projects. It's very important to choose the right type of project, or all of your effort could be wasted.
There are three basic types of science fair projects: models, demonstrations, or investigations. When you choose between them, you should consider two things. Before you do anything else, find out from the teacher what type of project the science fair rules require. Sometimes you get to choose the type of project. If so, pick one that lets you do what you are best at doing.
The Model Building Method
The model building method is the kind of project which, as the name implies, enables you to construct a model, to scale whenever possible, to illustrate a specific scientific principle. This can often be a real working machine, such as a simple crystal radio set, or a straightforward model, such as one of the solar system. Many of us have seen the model of an erupting volcano in which the chemical reaction between baking soda and vinegar causes realistic looking 'lava' flows down the sides of a 'mountain'. Even though models can be fun, and even exciting, they are usually appropriate only for elementary school, because they do not involve any experimentation or scientific exploration. Having said that, though, there can be some spectacular models produced by higher grade level students; especially if the model is actually demonstrating something new.
The Demonstration
The demonstration or descriptive method of research is again fairly self-explanatory. Here, you might display a collection of objects or interesting artifacts (for example, your rock collection) connected with a topic (geology) and describe them in detail on your display board, or in your report or speech. You could make a poster or project display board to explain your research on a particular topic. When you do this kind of project, you are not doing anything new, but only explaining or illustrating known scientific principles.
The Scientific Experiment (Investigation)
It is with the third of the possible methods that you can provide what most science fairs for older students are looking for - proper scientific experiments using scientific methods to construct and test a hypothesis and draw conclusions from it. If you want to go on to state or national science fairs, or are interested in a career in science, then this is an area to look into. And the choice of science fair project topics is limitless. Decide where your major interest lies - it might be biology, chemistry or physics but it could also be earth science, environmental science, sports science, meteorology or computer science - and then try to develop your own hypothesis and method of testing it. Books and web sites can be valuable sources for project ideas, but the more novel and distinctive your project, the more interested the judges will be.
And finally, you should remember to talk to your teacher. Make sure you understand the rules and guidelines completely, to assure your success. Then, no matter which type of project you choose to do, you can enjoy the experience, confident that you have chosen well!
