How to Choose the Right Type of Science Fair Project
Science fair projects can be the most memorable part of your science class, giving you an opportunity to show your abilities and creativity. Sometimes, it is hard just to get started on your science fair project. As a first step, make sure you understand the different types of science fair projects. Take the time to choose the right type of science fair project, so that your time and effort are not wasted doing the wrong things.
There are three different methods you can use for science fair projects: building (or modeling), demonstrating or investigating. When picking among them, there are two things to consider. First, read the science fair rules to find out what type of project is required, and be sure to confirm it with your teacher. Second, if you get to choose which type of project to do, pick the kind you find most interesting.
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 could be as simple as a model of the solar system, or a real working machine. 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'. These models can be fun to build and quite spectacular - but they are often more suited to elementary school science fairs because of the relative lack of real 'science' or creativity in most of them. Some students do create unusual or dramatic models, which can be used demonstrate new ideas.
The Demonstration
The demonstration or descriptive method of research is again fairly self-explanatory. You could display your collection of rocks or other items related to a particular topic (like geology), and describe how they are related in your report, speech or on a display board. As an alternative, you could use a visual project display board to describe the research you performed. If you choose this form of project, again you are not attempting new science; rather, you are illustrating and explaining scientific principles already known.
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 are interested in a science career, or would like to move on the regional or national science fair, then you should be looking into this area. And the choice of science fair project topics is limitless. Biology, chemistry and physics projects are common, but if your interest lies elsewhere, consider geology, environment, meteorology, or even sports science. Develop a hypothesis around your interest, and then find a method of testing it. There are many different books and web sites from which you can obtain ideas, but remember, the more individual and unique your project, the better your chances of winning.
Remember, it is important to keep your teacher informed about your progress, and confirm that you know the rules and requirements for your science fair. Then, whatever science projects you undertake, you can enjoy them with confidence!
