Step 1
Narrow your topic. Judges of life science fairs like to see specific projects that show a definite focused topic like: whether organic fertilizers are more effective, a comparison of plant growth using two different growth hormones, determining whether plants grow better in water or soil, which environmental factors favor decomposition by soil microbes, determining the gender of a person by looking at his or her feet, determining whether males and females have different pulse rates and investigating whether eating breakfast helps you perform better in school.

Step 2
Conduct the life science experiment with the judges. Involve the judges with your experiment to determine whether they perform better in class after eating breakfast by serving them an egg and some bacon and asking them to take a short quiz.

Step 3
Choose a project that allows you to bring in real-life props like stethoscopes for health projects and dissected frogs for anatomy projects.
-
Step 4
Create a life science fair project that goes slightly above your grade level. Everyone in your class is going to do the project that you just studied about last week. If you do a project that an older brother or sister might teach you, you may be able to impress the judges even further.
