Solid Ground? Measuring Soil Bearing Capacity

Science Fair Project Idea

Scientific Method

Foundations for many types of structures rest on soil. This project shows how you can investigate the bearing capacity of different types of soil. Read more

Do String Players Have Longer Left Fingers?

Science Fair Project Idea

Scientific Method

Physical activity is needed for maintaining normal bone strength and mass. Can physical stress on finger bones during development lead to an increase in finger length? Check out this project to see how violin players are an example of a "natural experiment" that you can use to answer this question. Read more

How Blue is Your Sports Drink?

Science Fair Project Idea

Scientific Method

Do you read the list of ingredients in foods and drinks before you buy them at the grocery store? If you do, you may have noticed that many of the items, especially colored drinks, contain dyes with names such as FD&C Blue 1, Red 40, or Yellow 5. But how much dye is needed to create all these colors? In this chemistry science project, you will build a simple spectrophotometer that is able to measure the concentration of colored chemicals in solutions. You will test your device by measuring… Read more

Playing the Angles: The Physics of Balls Bouncing Off of Surfaces

Science Fair Project Idea

Scientific Method

Think of hitting a baseball, heading a soccer ball into the net, or hitting a tennis ball with a racquet. Where the ball goes depends on...what? You can set up a simple model to start your investigation. You'll need a marble, a flat piece of wood, a flat piece of cardboard, a pencil, a ruler, a protractor, and a level surface. Lay down the cardboard down on a level surface and set up the flat piece of wood at one edge. The wood will act like a wall, and you're going to roll the marble at… Read more

Digital Photos and Dynamic Range

Science Fair Project Idea

Scientific Method

Digital cameras can be a great way to learn about photography. Most digital cameras today have LCD screens, so you get instant feedback on your photo. If you make a mistake, no problem, you just delete the picture. It's nice that you don't have to worry about the expense and bother of developing film! This project can help you learn to take better pictures. Read more

Can Peppermint Improve Reaction Times?

Science Fair Project Idea

Scientific Method

Did you know that some teachers give their students a peppermint candy on state testing days? Is it to give the kids sweet-smelling breath? Or are the teachers hoping for something more on the important testing day? In this human biology science fair project, you'll explore whether or not peppermint influences scores on different types of tests. Read more

The 'Ultimate' Science Fair Project: Frisbee Aerodynamics

Science Fair Project Idea

Scientific Method

Are you good at tossing a Frisbee®? It is great when you throw a perfect, arcing curve, right on target! If you can do that, you have already trained your arm on the aerodynamics of Frisbee flight. Why not treat your brain to some Frisbee science with this project? Read more

Make Your Own Piezoelectric Pickup for Acoustic Guitar

Science Fair Project Idea

Scientific Method

In this project you'll learn how to make a piezoelectric pickup for acoustic guitar using inexpensive components. You can then connect your acoustic guitar to an amplifier, and record your own music. If you are interested in electronics and like playing acoustic guitar, this could be the perfect project for you. Read more

Which Orange Juice Has the Most Vitamin C?

Science Fair Project Idea

Scientific Method

Which type of orange juice has the most vitamin C? In this science project, you will learn how to measure the amount of vitamin C in a solution using an iodine titration method. You will compare the amount of vitamin C in three different types of orange juice: homemade, premium not-from-concentrate, and orange juice made from frozen concentrate. Which do you think will have the most vitamin C? Read more

Testing Ant Repellents

Science Fair Project Idea

Scientific Method

Has your house ever suffered an ant invasion? This project is an interesting way to investigate what substances are effective as ant repellents. The goal is to find substances that keep ants away, yet are safe for humans and the environment. Read more
