Spare-Change Circus: Walking Coins on a (Vertical!) 'High Wire'

Science Fair Project Idea

Scientific Method

Here is a project that is almost like a magic trick: with a strong magnet and a simple apparatus you can build yourself, you can make a coin "walk" up and down a wire coat hanger! This project is an interesting way to learn about the distance over which magnetic forces act on magnetic materials. Read more

Dice Probabilities

Science Fair Project Idea

Scientific Method

You're playing Monopoly with a friend, and you've already got Park Place and you really, really want to get Boardwalk. If you're on Pacific Avenue, what are the chances you'll reach your goal? Here's an easy project that will show you how to find out. Read more

Movie Music

Science Fair Project Idea

Scientific Method

Have you ever seen a great movie and then rushed out and bought its soundtrack? Did the soundtrack bring back the thrill of an action chase? Or the sadness one of the movie's characters felt? Music is a big part of the movie experience. It intensifies the emotions in scenes so that you do not just jump when that hairy spider comes around the corner, you scream! In this music science fair project, you will find out if happy, sad, scary, and action scenes in movies use music with the same… Read more

What Do Different Baking Ingredients Do?

Science Fair Project Idea

Scientific Method

If you like to bake, this might be an interesting project for you. When you're following a recipe, do you ever wonder why certain ingredients keep showing up time after time (e.g., baking powder in quick breads)? Do you notice that certain ingredients tend to occur in a particular ratio to one another (e.g., amount of shortening and sugar, or amount of shortening and flour, or number of eggs and amount of flour)? What happens if you use more or less of an ingredient than the recipe calls… Read more

Around the World: The Geometry of Shooting Baskets

Science Fair Project Idea

Scientific Method

Take shots at a set distance from the basket, but systematically vary the angle to the backboard. For a basic project: How do you think your success rate will vary with angle? Draw a conclusion from your experimental results. A bar graph showing success rate at different angles can help to illustrate your conclusion. For a more advanced project: Use your knowledge of geometry and basketball to come up with a mathematical expression to predict your success rate as a function of angle… Read more

To Infinity and Beyond: Plan a City of the Future with Sim City.

Science Fair Project Idea

Scientific Method

Everyday, people in your city or town walk to school, ride the bus and go to work, and go to the library to research their science fair projects. But what if the library was 20 miles away from your home? Would you go to the library? What if there were no police officers or fire stations in your city, or if they were located across town, away from where most people live? What if there were no movie theaters? What would you do with your friends? Many people really like living in cities in which… Read more

With a Little Bread as Bait, Can You Make a Bird Migrate?

Science Fair Project Idea

Scientific Method

You might like to play in the autumn leaves and winter snow, but have you noticed that many birds don't like to stick around for the cold weather? And instead of the birds you're used to seeing in the warm months, your new feathered friends might be Canada geese. Why is that? Various types of birds and other animals travel from one place to another either in search of food, warmer temperatures, or other things they need to survive. This type of traveling is called migration. Try starting your… Read more

Renewable Energy Resources

Science Fair Project Idea

Scientific Method

Coal, gas, and oil are energy resources that are not renewable, meaning that once we use up the world's supply of these natural resources there will not be any left. There is a lot of debate about how long these resources will last. One way to ensure that we will not find ourselves in an energy crisis is to develop energy resources that are renewable. Renewable energy is a resource that cannot be used up. Investigate the many uses of renewable energy: solar energy, wind energy,… Read more

Ring of Fire 2: What Earthquakes Tell Us About Plate Tectonics

Science Fair Project Idea

Scientific Method

Today it is widely accepted that the Earth's crust consists of a series of huge plates that slowly move. The low parts of the plates are beneath the world's oceans, and the high parts of the plates are landmasses. New plate material is generated at deep sea ocean ridges in a process called sea-floor spreading. Material from plates is also recycled at trenches, where dense, oceanic crust dives back (subducts) underneath an adjacent plate towards the upper mantle. Figure 1 shows a map of the… Read more

How Do You Know Where You Are Without GPS? Dead Reckoning and Inertial Navigation

Science Fair Project Idea

Engineering Design Process

Put a meter stick on the ground. Starting at one end of the stick, close your eyes and try to walk exactly one meter. Open your eyes. How close were you? Now try it again with five, ten, or twenty meters. Does it get harder as the distance gets bigger? Without an outside reference from your visual system, it's quite difficult to know exactly how far you've gone! Electronic navigation systems face the same problem. Without an external reference like the global positioning system (GPS), it's very… Read more
