Make Your Own Markers
Science Fair Project Idea
Scientific Method
Do you ever wonder how markers are made? Where do all of those colors come from? Many of the colorful dyes we use come from plants. Could you create vibrant colored natural dyes? Could you turn these dyes into art supplies? You can! In this science project, become a scientist and engineer and make your own marker using homemade plant dye! Read more
Pencil Resistors
Science Fair Project Idea
Scientific Method
What do you do with your old wooden pencils when they get too short to hold? Don't throw them away; you can use them to make circuits! This project will show you how to use pencils to make resistors, an important part of many electrical circuits, and test how they affect the brightness of a lightbulb in a simple circuit. Read more
Baseball Bat Debate: What's Better, Wood or Aluminum?
Science Fair Project Idea
Scientific Method
So baseball's your game? Well, slugger, science and math abound in baseball. Just look at the zillions of "stats." In this project, you can produce some interesting baseball statistics of your own and perhaps settle a long-standing debate. You'll set up experiments at your local playing field to find out which type of bat is better, wood or aluminum. Play ball, and batter up! Read more
How Greasy Are Your Potato Chips?
Science Fair Project Idea
Scientific Method
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
Balloon Morphing: How Gases Contract and Expand
Science Fair Project Idea
Scientific Method
Expanding gases are everywhere, from the kitchen to the cosmos. You've tasted their pleasures every time you've eaten a slice of bread, bitten into a cookie, or sipped a glass of soda. In this chemistry science fair project, you'll capture a gas in a stretchy container you're probably pretty familiar with—a balloon. This will allow you to observe the gas expansion and contraction as the temperature changes. Read more
Suck It Up: Capillary Action of Water in Plants
Science Fair Project Idea
Scientific Method
Have you ever heard someone say, "that plant is thirsty" or "give that plant a drink of water"? We know that plants, and even bouquets of cut flowers, need water to survive, but have you ever thought about how the water moves within the plant? In this science project, you will use colored water and carnations to figure out where the water goes. Read more
How to Make a Piano Sing
Science Fair Project Idea
Scientific Method
The renowned pianist Vladimir Horowitz once said, "The most important thing is to transform the piano from a percussive instrument into a singing instrument." In this project, you will learn how you can make piano strings sing using sympathetic vibrations. Find out which notes make another one sing the longest by measuring their sound intensities using a smartphone equipped with a sensor app. Read more
Changing Constellations
Science Fair Project Idea
Scientific Method
Do you like to look up into the night sky? There are so many stars, it can be mind boggling! Some ancient people marked time by the changes in star patterns. We still use changes in constellation patterns to mark astronomical time. Do constellations change more in one hour, one day, one month, or one year? Read more
The Brains Behind 'Where's Waldo?'
Science Fair Project Idea
Scientific Method
What makes you notice someone in a crowd? Why do some things stand out, while others melt into the background? In this science project you can investigate the psychology of how things get noticed, by studying how our brains perform a visual search. Have you ever looked and looked desperately for something? It is so frustrating! The classic example is when I lose my keys. You would think that by now (knowing that I am the kind of person who often loses my keys) I would have a huge, bright red… Read more
How Well Do Different Materials Create Static Electricity?
Science Fair Project Idea
Scientific Method
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
