This science fair project idea examines whether plants are still able to grow normally if they are turned upside-down.

Before you get ready for a delicious scramble or omelet, add a bit of science to your morning routine!

Help kids tap into their inner inventor by teaching them how to make peanut butter through trial, error, and lots of taste testing!

This science fair project idea explores substances that cause a bubble to last longer.

In this physics project, learn about the relationship between light intensity and distance using a laser pointer, flashlight, and graph paper!

Build a 3d animal cell model with this cool science fair project, which helps kids visualize and understand the function of a cell's parts and organelles.

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.

In this activity, your child will be challenged to build a tall tower out of building bricks! The instructions include questions prompts to guide students through the design challenge.

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.
