Science Fair Project Idea
You have probably read all about forms of alternative energy like solar and wind power. But what about human power? With the aid of a coil of wire and some magnets, you can generate electricity with nothing more than a flick of your wrist. In this project, you will build a small hand-powered electrical generator that can power a series of tiny lights. Get ready to save the planet and get some exercise at the same time! Read more

Juice boxes are so convenient—just poke the straw in and sip away! But have you ever noticed that some juice boxes don't seem to have much juice, even when they have a lot of packaging? It might surprise you how much thought goes into the design and manufacturing of a juice box. Each manufacturer has carefully calculated how big each side should be to hold a certain amount of juice inside. In this science project, you will find out how different brands of juice measure up.

"Hey kids, step right up! Toss this ball and win a prize!" shouts the carny barker. Sounds easy enough—until you try it. Why are those "simple" games at the fairs, carnivals, and boardwalks so hard? Is it really lack of skill or coordination or do those concessionaires use some basic laws of science to help them set up the games in their favor? This science fair project can help you find out for yourself. Read more

Have you ever been to a buffet and found yourself surrounded by a wide variety of taste sensations? People are generally able to discern five basic tastes: sweet, umami (also known as savory), salty, sour, and bitter. How sensitive is a person's tongue for these basic tastes? Is it easier to detect some flavors at low concentrations compared to others? In this human biology science project, you will find out by exploring your taste thresholds for sweetness, saltiness, and sourness. Get ready to… Read more

Did you know that soils can be alkaline, neutral, or acidic? Most plants grow best in soil near neutral pH, but some plants prefer slightly acidic and others slightly alkaline soil. What is the pH of the soil in your garden? What happens to the pH of water that comes in contact with soil? In this science project you will get to find out. Read more
Science Fair Project Idea
When your parents were kids, they probably wore polyester. Static cling was a major household issue! Now everybody wears cotton, which does not get static cling nearly as much. Why are some materials more susceptible to static cling than others? Investigate how well different materials produce static electricity by making a homemade electroscope and testing it out in this science project. Read more
Science Fair Project Idea
Do you like playing with play dough; or modeling clay? Wouldn't it be cool if you could add lights, sound, or even motion to your play dough creations? In this project, you will use play dough that conducts electricity, which will allow you to connect lights to your sculptures! This project is the first in a three-part series on play dough circuits, which can all be done with the same materials. We recommend doing the projects in order. Read more

One of America's favorite snacks is potato chips. Although potato chips are very tasty, some varieties are not very healthy for you. A typical 1-ounce (oz.) serving of a well-known national potato chip brand contains 150 calories, 90 of which are from fat. How greasy are your favorite potato chips? Try this science fair project, and you'll get a visual understanding about how much oil a potato chip can hold. Read more

If you leave an ice cube out on the kitchen counter and come back to check on it in awhile, what do you find? A puddle! The same thing happens to ice in nature—if the temperature gets warm enough, it melts. In this ocean science project, you will find out what happens to sea levels if the ice at the North Pole melts, or if the ice at the South Pole melts. It is an important question for the millions of people who enjoy living along the coasts of the world. Read more
