There are three different and distinct types of projects. What is acceptable for an elementary school science fair project may not be for a high school or middle school science fair project. Also, state, regional or national science fairs may have different rules. If you do the wrong kind of project, it can keep you from going on to those larger science fairs. Plus you could end up with a bad grade, even after all your hard work.

So, let's talk about the three main kinds of projects so that you understand what is expected at your school.

1. A Model Kit

In this type of science project, a display of some kind is assembled in order to illustrate something related to science. A famous example is the "erupting volcano" model. This is a plaster model of a volcano that is filled with baking soda and vinegar; the reaction between the chemicals causes a violent foaming which erupts like lava. This type of science fair project requires the least amount of work, and lacks the creativity that judges look for. it is sometimes used for elementary school science fair projects, but is rarely appropriate for middle school or high school.

2. The Demonstration

Like building a model, the "demonstration project" is often discouraged or even forbidden at some science fairs. It does not answer a question through experimentation, but instead illustrates a know scientific principle by demonstrating it. A tornado in a wind tunnel or an "oil drop" model of splitting the atom are examples of a "demonstration" science fair project. This type of project is discouraged because it doesn't challenge the student to think critically about scientific ideas, principles or procedures.

3. The Investigation

This is what most science fairs are looking for. It is a proper scientific experiment, using the scientific method to seek out unknown answers to hypothetical questions. Basically, it's an experiment. if you want to advance to state, regional, or national science fairs, then this is probably the best type of project to choose.

Now that you know about these three types of school science fair projects, it is important to ask your teacher about which will be acceptable for the assignment.
