Alternate Methods of Testing Seed Viability For grades 7 thru 11 Category: Botany Hypothesis: Hydrogen peroxide will loosen the seed coat more efficiently than the hydrochloric acid and the isopropyl alcohol, and that it will cause the least amount of damage to the seed. Primary Materials Used: Petri Dishes Kentucky Bluegrass Seeds, Hydrogen Peroxide, Hydrochloric Acid, Isopropyl Alcohol, Triphenyl Tetrazlium, Microscope, Blotter Paper, Seed Strainer, Seed Piercer, White Labels, Warm Oven Click Here for more details about the "Alternate Methods of Testing Seed Viability" science fair project.

How Does Incubation Temperature Affect the Sex Ratio of Fruit Flies? For grades 7 thru 10 Category: Zoology Hypothesis: Female fruit flies will outsurvive the male fruit flies because they have to go through much more harsh labor than the males. Primary Materials Used: Fruit Flies, Incubator, Vials, Fly Anesthetizer, Magnifying Glass, Tweezers, Thermometer Click Here for more details about the "How Does Incubation Temperature Affect the Sex Ratio of Fruit Flies?" science fair project.

What Causes Absence of Relative Pitch? For grades 6 thru 10 Category: Behavioral Science Hypothesis: Subjects with Lost-Key or Atonal phenotypes will have a measurable defect either in hearing or in encoding/retrieving relative pitch intervals (memory). Primary Materials Used: Accordian, Electronic Keyboard, Chromatic Tuner Click Here for more details about the "What Causes Absence of Relative Pitch?" science fair project.

What’s in Your Milk? For grades 8 thru 12 Category: Chemistry Hypothesis: Unpasteurized samples of different types of milk will develop more bacteria than pasteurized samples.
