Learn whether Mylar Balloons last longer than Latex Balloons or vice versa.

Learn the basic structure of a DNA strand, which is the double helix, how genes form together, and the resemblance DNA has to a twisted ladder. Create a model.

How do series and parallel circuits work, and which produces the brightest light in a light bulb? Construct both in this project and find out!

This science fair project idea researches the different layers of the atmosphere and creates a visual representation of the atmospheric layers.

Why do ants like sugar? Do ants like artificial sweeteners too? Kids find out with this great inquiry-based science fair project.

Young physicists will wrestle with a discrepant event: the Hammer Ruler Trick. They'll make some inferences about torque, balance, and center of gravity.

Do you love to make Jell-O? Find out in this science fair project idea if it is possible to make Jell-O with just warm water.

This science fair project idea investigates how color affects temperature.

In this project, you will observe and record changes in sunspots over two weeks.

This science fair project idea determines what household items are good conductors of electricity.

This project examines if computer screen and text color affect retention and if people subconsciously prefer combinations of colors that help their retention.

Is there a relationship between caffeine and heart rate? Students will determine the effect of caffeine on heart rate in this fun science fair project.

This science fair project idea creates a sedimentary rock and to investigate what takes place during the rock cycle.

The objective of this science fair project idea is to determine if sound travels best through the air, water or a solid.

In this microwave plant experiment, find out whether microwave radiation will affect radish seed germination. Will it help or hinder the plants' growth?

In this science fair project, you'll make a "ghost" appear in a test tube, and learn about what happens when hot water and cold water interact.

Will potatoes spud or sprout faster in dry, dark, or cold conditions? Find out in this science fair project idea!

Use chemical analysis to identify a variety of mystery powders that look the same but actually have very different properties.

This science fair project idea explores the different properties of matter.

This project demonstrates the correspondence between the volume of water displaced by a submerged object and the volume of the object displacing it.

This science fair project creates a visual model of whatâs happening to sound waves as a car approaches and then leaves.

Find out whether a longer airplane will fly farther or a wider paper airplane.

This science project has students study a group of volunteer liars actively lying to study the behavior of a lie. Students see if they can figure out the truth.

This science fair project focuses on the use of the enzyme amylase found in human saliva to break down starch into sugar.

In this science fair project, students create their own miniature salt flats at home.

Brine shrimp usually live in saltwater. Investigate how salt concentration (salinity) affects the rate at which brine shrimp eggs hatch.

In this cool project, create a lighted, scale model of the different layers of the Sun, including the core, radiation and convection zones, and photosphere.

Science fair project which determines whether the size or the thickness of a piece of paper has an effect on how many times it can be folded in half.

The objective of this science fair project is to observe the differences in heat absorption for darker colors vs. lighter colors.

Science fair project which compares the rate of temperature change and the maximum temperature as a result of the angle of light radiation.
