Why does purple cheese look nasty? Because color plays a big part in how we perceive the taste of different foods. Are birds just like us in this respect?

This science experiment tests whether warm or cold water works best in making cut flowers last longer.

Science fair project that determines whether cooling eggs helps them be peeled more easily. Compare the time it took to peel each egg.

Make a backbone model to explore human anatomy and life science.

Saturn is the ringed planet in our solar system, a gas giant with rings made of ice and dust. Let's make a cool scale model with an old CD and some glitter!

In this project, build an insect model that shows how the head, thorax, and abdomen fit together! Learn insect anatomy by constructing a paper mache critter.

Do different types of oil mix or stack? Find out in this science fair project idea!

Are you ready to be a detective for science? Then get out your magnifying glass and start studying fingerprints!

Learn about sound physics and do a survey experiment to explore the difference between sound and noise in this science project.

In this experiment you observe and determine how well your cat uses his whiskers to navigate through a maze.

This science fair project idea examines which type of insulation holds in the most heat.

The objective of this science project is to determine the length of time for different seeds to germinate.

How do animals keep warm? In this experiment, find out whether fat insulation resists cold temperatures and learn how this works in the animal kingdom.

Test whether plants can grow without sunlight and water.

This science fair project idea determines which method of hand cleansing is the most effective.

Handedness and footedness refer to whether people prefer to use their left or right hand and foot. In this experiment, test hand and foot dominance.

Spiders don't go to grocery stores or fast food chains to get their food -- they set up traps and wait for their food to come to them!

This cool science fair project teaches kids about temperature, density and buoyancy using balloons that float with normal air. No helium required!

This science fair project idea investigates the difference in reaction times between boys and girls.

This science fair project idea explores how the shape of a boat affects its density and how much weight it can float.

This science fair project will help students learn about non-vascular plants, such as mosses.

In this sound experiment children listen for differences as they tap on a bag of air, a bag of water, and a wooden block held up to their ears.

Did you ever add salt to pasta? Did it help cook the pasta faster? If not, find out in this science fair project idea.

This science fair project idea demonstrates that plants give off water.

Did you even wonder why some rocks are round and smooth while others are broken up into small pieces?

In this classic Ivory soap experiment, kids learn what happens to different types of soap in the microwave, and why!

When you rub a balloon on your head, your hair stands up; but is that true for everyone? Does hair color affect static electricity?

Learn about the role of Earth's rotation on the Coriolis Effect and hurricanes in this science project. Model the Coriolis Effect on a hurricane's direction.

This study evaluates if electronic devices commonly found in most households emit radiation, and if they do, how much?

In this science fair project, we'll use a liquid crystal thermometer to find out whether exercising makes a difference in people's temperature.
