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 experiment, kids will see if pruning tomato plants makes them more fruitful and learn about the factors that contribute to a plant's fruit production.

This science fair project idea explores plant growth from a bulb, root, and a stem and investigates asexual plant reproduction.

Step into the fantastic world of colors with a project that explores what shade you -- and your friends -- like best.

This fun experiment provides a concrete and visually striking illustration of photosynthesis.

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

Kids often ask, "how tall am I?" This science fair project seeks to determine how well kids can guess their own heights.

This science fair project explores how osmotic pressure forces water through the root up into the plant.

This science fair project uses paper chromatography to investigate whether black, brown, orange, and purple are pure colors or mixtures of other colors.

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?

Marshmallows are made of sugar, water, and air pockets. Since the marshmallow is flexible, will air pressure cause it to expand when heated in a microwave?

This science project encourages students to investigate the Mozart Effect, the idea that classical music promotes learning.

Science fair project that teaches you about chemical indicators and how to make your own in order to identify various mystery solutions.

This science fair project idea explores whether a plastic slinky works as well as a metal slinky when walking it down the stairs.

Stories change as you retell them. The objective of this science fair project is to demonstrate how information gets interpreted, distorted and changed.

Can a horse lead itself to the carrot? Train your horse with carrots and boxes and test horse memory in this fun zoology science fair project.

Is it amplitude? Weight? Length of string? Kids will discover what factors changing the period of a pendulum depends on in this fun and easy physics experiment.

Find out whether soil amendments can improve soil conditions and help you grow a bigger beanstalk in this ecology experiment!

With this science fair idea, little scientists will gain valuable insights into the physics behind throwing a baseball.

In this science fair project, kids measure how weather conditions affect how fast a puddle evaporates.

Science fair project which tests various sedimentary, igneous and metamorphic rocks to find out whether one rock family is stronger than the others.

Science fair project in which you will learn more about the natural world by preserving and identifying different animal tracks.

This science fair project introduces children to static electricity and the idea that electricity is more than lights and plugs.

This science project teaches students the relationship between compost and plant growth. Students conduct an experiment with different types of compost.

Did you know a mouse eats almost fifty times as much as a cow? Find out how and test out the strange science with your friends!

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

Collect meteorite dust with a magnet in your very own backyard! The objective of this science fair project is to gather meteorite dust to study outer space.

What do ants eat? Kids find out by observing a colony of ants in this cool zoology science fair project for 4th grade.

What do worms eat? Kids find out what kinds of rotting leaves and vegetables worms prefer in this cool compost science fair project.

This science fair project idea examines whether boys and girls differ in reflexes.
