This science fair project idea teaches that time always passes at the same rate and nothing we do in our daily life âreallyâ affects how fast it moves.

In this project children practice the scientific method while playing with puffy paint.

This engaging project encourages young children to practice and refine the important scientific skills of sorting and classification.

What animals are most popular? This project affords practice in data-collection, record-keeping and data-analysis through the investigation of this question.

In this cool science fair project idea, kids conduct the ruler drop test on volunteers to determine whether reaction time can be improved with practice.

Examine whether distilled water, spring water, or regular tap water yield faster plant growth.

Find out whether packaged seeds actually do expire in this new science fair project idea.

Watch pre-packaged seeds and seeds taken from inside fruits and vegetables grow. Which ones will grow faster? Read more in this science fair project idea.

Young scientists will investigate people's preferences for saltiness, and make some inferences about genetics and diet.

Ever wondered how a plant drinks water? This science project will teach you how and help you create a beautiful floral display!

This project explores whether plants can live and grow when "watered" with juice, soda, or milk.

How do organic materials become soil? This science experiment measures what materials biodegrade.

Test whether plants can grow without sunlight and water.

Do plants get crowded? Have your curious kid investigate how plants respond if they're forced to grow together in a confined space.

Water, along with soil and light, is a necessary component for plant growth. So what's better for promoting plant growth: tap water, or rain water?

This project is a vivid, concrete introduction to the basic but important idea that plants need sunlight and water to grow.

These science fair experiments demonstrate the chemistry of rust and the oxidation process.

This science project challenges students to study deer behavior in their natural habitat- the feeding patterns, social behaviors, male to female ratio, etc.

Have you ever seen fruit decay? Find out if a fruit will rot faster if you open it versus leaving it untouched!

How well can people recall what they have observed. Test your knowledge in this fun experiment.

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

Word color association is just a fancy way to talk about the way we connect colors with words.

This science experiment tests if dog saliva can really help heal wounds.

Plants and light seem to be good buddies, but how far does the friendship really go?

This science fair project idea determines if the color of light affects the growth of plants.

Find out whether putting something on top of a plant will inhibit its growth.

Demonstrate how static electricity can cause an object to move. It also examines just how an object affected by static electricity will move.

This experiment challenges students to forecast the weather based on the surrounding areas' weather.

In this science fair project, kids start a chemical reaction that will make a balloon inflate itself!

The objective of this science fair project is to explore the relationship between acidic and basic compounds.
