How to Do Successful Science Fair Projects

Types of Science Projects         

Types of Science Fair Projects

There are five types of science projects.

1. Original Research
In this type of science fair project you perform your own research to test a hypothesis with the scientific method.
Example: The effect of sleep deprivation on the health of rats.

2. Demonstration
In this type of science fair project you retest an experiment that has been done by another individual.
Examples: (1) Demonstration of Coulomb’s Law, i.e., the force of attraction or repulsion between two charged points is directly proportional to the product of the charges and inversely proportional to the square of the distance between them and (2) Demonstration of the corpuscular and wave nature of light.

3. Investigation
In this type of science fair project you gather information about a topic, write a report, and present your results with posters and other visual aids.
Examples: (1) Description of the discovery of the structure of the DNA molecule by James Watson and Francis Crick and (2) Description of the discovery of cosmic neutrinos, which are formed in the thermonuclear fusion process that powers the sun and other star by Raymond Davis and Masatoshi Koshiba. 

4. Collections
In this type of science fair project you present a collection of items and discuss the scientific principles that the collection illustrates.
Example: Collection of insects illustrating adaptive characteristics such as colors and patterns that have evolved for disguise and deception.

5. Models
In this type of science fair project you present a model to illustrate a scientific principle, prototype of an invention or new design, or an inexpensive construction of a costly scientific apparatus.
Examples: (1) The construction of a robot and (2) The construction of a spectrograph system for $300 when commercial units cost $20,000 to $100,000. This spectrograph was an entry of one of the finalist in the 2007 Intel Science Talent Search.
