Guitar Fundamentals: Wavelength, Frequency, & Speed

Science Fair Project Idea

Scientific Method

This is a rockin' project for guitarists with an interest in the physics behind the music. Have you ever wondered why the pitch of the note changes when you fret the string? You can find out for yourself with this project on the fundamental physics of stringed instruments. Read more

Foggy Forecasting: What Weather Factors Create Radiation Fog?

Science Fair Project Idea

Scientific Method

The poet Carl Sandburg wrote, "The fog comes on little cat feet..." In this weather science fair project, you'll discover why this beautiful, quiet creeper appears on some days, and not on others. If you are fascinated by fog and weather conditions, this science fair project is for you! Read more

Macroinvertebrates as Indicators of Pollution

Science Fair Project Idea

Scientific Method

In this science project, you will collect macroinvertebrate samples from multiple points along a body of water, ideally a small creek or stream, and test the pollution burden and biodiversity of small organisms or insects to see if pollution impacts biodiversity. Read more

Can Your Body Temperature Tell the Time of Day? Find Out with Human Circadian Cycles.

Science Fair Project Idea

Scientific Method

Have you ever had to adjust to a new time zone and noticed that it takes a while before you start to feel normal again? By shifting your sleep and activity schedule, you have altered the pattern of your body's circadian rhythms. Human beings, like many other living things, have a number of internal processes that show a distinct circadian rhythm. The most obvious is our sleep cycle, with activity during the day, followed by sleep during the night. Circadian rhythms have also been demonstrated… Read more

The Curdling Properties of Different Milks: How to Avoid Little Miss Muffet's Curds

Science Fair Project Idea

Scientific Method

Has a milk-based soup, sauce, or gravy ever curdled on you (formed lumps) as you were preparing it? Curdling is the process of coagulation that occurs where the proteins in the milk clump together. Sometimes curdling is desirable—for example, if you want to make a delicious cheese or yogurt—but if you are trying to make a milk-based soup or gratin, or if you're adding milk to a hot drink, curdling is very unwanted because you lose the smooth, creamy texture. Nobody likes clumps and… Read more

Motorizing a Robotic Hand

Science Fair Project Idea

Scientific Method

Imagine how cool it would be to have your own motorized robot hand. Well, stop imagining and turn that daydream into reality! Start out by designing and building a robot hand. The Science Buddies project Grasping With Straws: Make a Robot Hand Using Drinking Straws shows you a simple way to make a robot hand with drinking straws, or you can design a robot hand from any other materials you think are suitable. Your hand design will need sewing threads, or some other mechanism, for motors to… Read more

How to Make a Guitar Sing

Science Fair Project Idea

Scientific Method

This is a great project for a musician who is interested in the physics of stringed instruments. If you've ever played an acoustic guitar, you may have noticed that picking a single string can make one or more of the other (unpicked) strings vibrate. When this happens, it's called sympathetic vibration. What intervals lead to the strongest sympathetic vibrations? Find out for yourself with this project. Read more

A Sweet Sequence: The Cacao Genome

Science Fair Project Idea

Scientific Method

Can you imagine Valentine's Day or Halloween without chocolate? Well, if you're a chocolate lover brace yourself for the bad news. According to the United States Department of Agriculture (USDA), "Worldwide demand for cacao now exceeds production." If there isn't enough cacao, the major raw ingredient for chocolate, then the chocolate supply will dwindle. Hang on! Before you start rushing to the store to buy all the chocolate you can get your hands on, a solution is already in the works. In… Read more

What Do We Do With Our E-waste?

Science Fair Project Idea

Scientific Method

If you made a pile of all the electronic devices (cell phones, computers, stereos, televisions, MP3 players, video game systems, remote-control toys, etc.) that your family has gotten rid of since you were a baby, how big would that pile be? Would it be taller than you? Would it fit better in a wheelbarrow or in a pickup truck? And did they just throw it in the trash? In this science project, you'll explore what people in your community do with electronic waste, commonly called e-waste, and… Read more

Mean & Green: Fruit & Vegetable Hardening

Science Fair Project Idea

Scientific Method

When you open a can of green beans, have you ever wondered why the beans are not mushy, or more like a puree? Canning requires boiling the beans for a long period of time to kill bacteria, so why don't the beans fall apart into small pieces? Some fruits and vegetables—like cherries, apples, potatoes, sweet potatoes, beets, carrots, beans, cauliflower, and tomatoes—have the ability to undergo hardening, or firming of their plant tissues. A special enzyme, called pectin methyl… Read more
