thumbnail Do you ever wonder how pirates sailed the seven seas? The two most important things a pirate could have (besides a parrot and big hat) were a compass and an accurate watch. Ancient navigators didn't know about compasses, so how did they know where they were going? Could they have used the stars to know which way to go? Read more

thumbnail Do you live someplace where you get to experience the full glory of all four seasons? If so, you know well the heady blossoms and dramatic skies of spring; the long, sun-drenched days of summer; the trees shaking in crimson and gold in fall; and the sparkling, brittle snows of winter. But you might not know why we have these seasons, over and over again, in a cycle as predictable as the rising and setting of the Sun. The reasons for the seasons are surprising and have to do with Earth's tilt… Read more

thumbnail "What?! Many of my toys are also machines?" That's right—simple machines! Simple machines are everywhere! Under your feet when you climb stairs, in your hand when you use a utensil to eat your dinner, even in your arm when you throw a ball. Come visit this science fair project and explore the six types of simple machines. Find out how many are hiding under the hinged lid (yes, another simple machine) of your toy box! Read more

thumbnail How far would you have to travel so that the light of the full sun would provide "daylight" no brighter than twilight on Earth? This project describes a method to verify the inverse square law: how light, sound, electrical signals, and gravity each decrease with distance from their source. When you have finished your experiment, you can use your results to calculate an answer. Read more

Science Fair Project Idea
thumbnail You are right next to the basket and someone passes you the ball. Will you go for a direct shot or will you use the backboard and take a bank shot at the basket? Would different positions on the court give you a higher chance of making a shot using the backboard than others, even when keeping the distance from the hoop the same? In this science project, you will build a scale model and test different positions on the court to determine if one results in a better chance of making a bank shot… Read more

thumbnail This is a great project for someone interested in both stargazing and photography. Bright city lights and even the light of the full Moon obscure the dimmest stars, which can make identifying constellations more difficult. In this astronomy science project, you will calibrate a digital camera to measure the skyglow in different locations. This can be a great tool to comparing the quality of different star viewing locations. Read more

thumbnail On a rainy day, do you ever wonder what the weather is like on the other side of the planet? Different regions around the globe can have very different seasonal weather patterns. In this experiment, you can test if these seasonal variations are related to which hemisphere each region is located in. Read more

thumbnail What do humans need to survive? We need food, water, and warm shelter. We all need a warm place to live, particularly when it's chilly outside. How do many of us warm our houses or apartments? We depend on fossil fuels to supply gas and electricity to our heaters. But burning fossil fuels to create energy is harmful to the environment. What if there was a way to warm our homes without burning fossil fuels and it was free? In this science fair project, you will build a solar air heater and see… Read more

Science Fair Project Idea
thumbnail It's the bottom of the ninth, and you've spent a great afternoon at the ball game with a hotdog, a soda, and an ice cream in hand, but I'll bet you're not thinking about how many crops went into those classic baseball snacks. Sure, the bun contains wheat, but did you know that the hotdog might contain wheat, too? And soybeans may have been used to give that ice cream its perfectly smooth texture, while corn was likely used to sweeten the entire meal! Crops can be changed and added to processed… Read more
