It can be a challenge to come up with a science fair project idea. There is fierce competition to come up with the coolest idea, plus you need a topic that is considered appropriate for your educational level. I've arranged science fair project ideas by topic, but you might like to take a look at ideas according to education level.

A well-designed project at the college level can open the door to future educational and career opportunities, so it pays to put some thought and effort into your topic. Answer a question, test a hypothesis. College students usually have a semester to complete their project, so you have some time to plan and conduct your research. The goal at this level is to find an original topic. It doesn't have to be something complicated or time-consuming. Also, appearances count. Aim for professional-quality images and presentation. Handwritten work and drawings won't work as well as a printed report or poster with photographs.

  • How close does a plant have to be to a pesticide for it to work? What factors influence the effectiveness of a pesticide (rain? light? wind?)? How much can you dilute a pesticide while retaining its effectiveness? How effective are natural pest deterrents?
     
  • What is the effect of a chemical on a plant? You can look at natural pollutants (e.g., motor oil, runoff from a busy street) or unusual substances (e.g., orange juice, baking soda). Factors that you can measure include rate of plant growth, leaf size, life/death of the plant, color of plant, and ability to flower/bear fruit.
