Maybe you already know what you want to do or maybe you're clueless. Whatever you decide, here are steps you should consider when doing your project.
Judges always look for original ideas.
Original projects are those that take the textbooks one step further by exploring new ground and innovative techniques. Your project could be original in the scientific concept or maybe you've come up with a new way to solve an old problem or a new and better way to interpret the data. Whatever your project, make sure it is done well. Just having a great and new idea is only half of the solution. A direct, often simple objective won't leave the judges scratching their heads, trying to figure out what exactly you were trying to prove.
