    I recently judged a Jr. High science fair. Some of the fair projects were really creative.

    "They color of cool"Can the color of shingles affect the temperature of a house?

    "Night Writers" - How does lack sleep affect your motor skills? They had people stay up all night giving them typing test at various points of the night and after things like drinking a cup of coffee.

    "The unpopables" - Which brand and/or flavor of popcorn has fewer un popped kernels ?

    There were so many that were great. but these are the ones that I remember as the best

    For my science fair project, I researched the affects of farting. (no joke). Get 2 3 liter bottles (empty) and fill one with one food, and the other with another. Add a half a cup of soil (for bacteria to form) then put a balloon over the top (no cap). Monitor how big the balloon gets for one week and BAM! A perfect science fair project. Hope I helped!

    I did a science fair project, where I took four of the same plants and used the sunlight and a black light. To see if sunlight makes a plant grow better or will a black make them grow better. I know which one makes them grow better. But just do the project and find out.

    Source(s): I did this when I was in the 8th grade.

    In England we don't do science fairs, so I'll give it my best shot.

    How antiacid tablets work - some acid and some milk of magnesia, stick them together and explain. Also demonstrate film canister rockets as they are fun.
