College Science Fair Projects by Topic 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.   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.

Handwritten work and drawings wont work as well as a printed report or poster with photographs.

Does seed size affect the growth rate or final size of a plant?How close does a plant have to be to a pesticide for the pesticide to work? What factors influence the effectiveness of a pesticide, such as rain, light or 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?

Factors that you can measure include rate of plant growth, leaf size, life/death of the plant, the color of the plant, and ability to flower/bear fruit.How does cold storage affect the germinatio n of seeds? Factors you can control include the type of seeds, length of storage and the temperature of storage, light, and humidity. Food How does the shape of an ice cube affect how quickly it melts?Do the same types of mold grow on all types of bread? Are certain preservatives better at inhibiting dangerous molds than others?Is the nutritional content of different brands of a vegetable (such as canned peas) the same?
