Science fair project that demonstrates the process known as refraction, which allows glasses and contact lenses to help people with poor vision.

This science fair project idea investigates if webbed feet help a duck (and others) swim.

Science fair project that demonstrates how a rainbow forms, by using water to split white light into its many colors.

Science fair project which identifies the most effective insulator that you could use to make a winter coat by comparing how well cloth and cotton trap heat.

In this science fair project, students test how objects float and sink in liquids of different densities.

This science fair project idea investigates if heat from direct sunlight is hotter than heat from reflected sunlight.

Give your number one dad something that he truly deserves this Father's Day!

Science fair project in which you will attempt to throw a ball the greatest horizontal distance possible by using different angles.

This experiment will examine and precisely measure the amount of sugar in various sodas.

This project tests the hypothesis that dark colors absorb more heat than light colors.

In this CD hovercraft science project, students will construct their own DIY hovercraft.

This simple and creative arts and crafts activity is great for preschoolers or kindergarteners and uses recycled magazines or newspapers.

This classic children's game demonstrates how sound travels through air vs. through a solid.

How does a kazoo, the strings of a guitar, or the speaker of a radio make sound? The purpose of this science fair project is to show how vibration makes sound.

In this Bernoulli's Principle experiment, you'll learn how an increase in the speed of a fluid, like air, decreases pressure.

Science fair project that examines the relationship between the size of a bubble and how quickly it falls. What is the correlation?

Here's a great activity that uses corks and toothpicks to create a fleet of floating boats. Which design makes for the most seaworthy vessel?

Stir up some friendly competition with this tabletop bow and arrow craft!

In this science fair project, students focus sunlight with a magnifying glass and trap shorter waves to melt ice.

In this experiment, students find out what happens when a less-dense fluid interacts with a denser one, replicating the effect of cooler solid rock on magma.

This science fair project idea lets you can create your own Faraday Cage!

This science fair project demonstrates the principles of reflection through simple experiments involving mirrors and light.

Demonstrate how you can make your own compass using a magnetized needle. It also allows you to compare magnetic north and geographic north.

This conservation of energy demonstration shows why the first hill is the highest on a roller coaster. Learn more about potential and kinetic energy!

Science fair project that tests the effects of diluted soap on the size of bubbles blown from the solution. Will dilution cause smaller bubbles?

This awesome diffraction grating experiment puts high school students' applied math skills to the test by having them calculate the wavelength of laser light.

In this activity, your child will learn about a style of gardening that uses moss, also called "kokedama."

Air invisible; it doesn't make sounds; you can't pick it up and throw it. So how do we know it exists? Help your second grade scientist figure it out.

In this science project, the center of gravity is explored.

In this project, waves of vibrations are experimented with using water in glasses.
