This project examines the vulnerability of fruit flies, Drosophila melanigaster, to irradiation. Will exposure result in mutations?

It's easier than you think to make homemade play dough -- just a few pantry staples makes a natural version of the toy that kids have loved for generations.

Study structure of the lens found in the human eye and determine whether it is concave or convex. Prepare a ray diagram, formulate hypothesis.

Explore the role of starches as thickening agents in food, and learn about the chemical properties of starch in the process.

This science fair project idea explores if people with cool skin tones prefer cool colors and people with warm skin tones prefer warm colors.

Does fear cause the same physiologic responses in men and women? This experiment measures people's blood pressure and heart rate while watching a scary movie.

This first grade science activity brings the green grass of early spring inside while teaching your child about the cycles of growth.

The objective of this science fair project is to examine the cleanliness of salad preparation techniques.

This science fair project explores different types of endangered frogs, and why some are endangered while others are not.

In this experiment, students will discover how heat and pressure turn clay into slate, phyllite, and finally schist.

In this middle school activity, your child will learn how to press plants and create her very own herbarium, or plant library! Here's how:

Research different measurement systems, design your own new or improved system that can measure something difficult to measure with traditional systems.

Here's how you and your teen can stage your own formal debateâbeyond arguing why chores are unethical! Formal debates improve teens' critical thinking skills.

Here's a household scavenger hunt that shows kids the natural sources behind everyday objects...and builds reading skills, too!

This project examines whether more expensive golf balls translate into better results on the golf course.

This science fair project idea explores whether dogs do look like their owners.

The projects describes the correlation between Gravel Run and Centreville Landing in terms of pH, dissolved oxygen, turbidity, and temperature.

This fun marbled paper craft uses things you're likely to have around your house, and it teaches kids some simple chemistry too!

This science fair project teaches you about what makes persimmons so tart and how astringency can be removed by studying the effect of tannins on fruit.

In this fun science fair project idea learn the difference between additive and subtractive color and why they are handled differently.

The purpose of this science project is to determine which stimulus, gravity or water, will cause the greatest growth response in a plant.

What is surface tension? Kids will discover how water-skating insects use surface tension to keep from sinking by making a model water walker.

The objective of this science fair project is to analyze the effects of salinity and temperature on water.

Young physicists learn about apparent weightlessnessâthat weird sensation you sometimes feel in elevators, turbulent airplanes, and roller coasters.

Conduct a simple science experiment to see if flowers from your garden pass the acid-base indicator test with this exciting chemistry activity.

This science fair project idea produces varying pitches of sound.

What is the Doppler Effect, or the Doppler Shift? The purpose of this science fair project is to determine how distance impacts the Doppler Effect.
