Stop the Train! Magnetic Brakes for a Maglev Train

Science Fair Project Idea

Scientific Method

Did you know that you can use magnets to build a train that floats above its tracks? In this project, you will also use magnets to make the train stop, preventing it from crashing into the end of the track. Will adding more magnets help the train stop sooner? Read more

Chemistry of Baking Ingredients 1: How Much Baking Powder Do Quick Breads Need?

Science Fair Project Idea

Scientific Method

If you like to bake, this could be a good science project for you! Have you ever wondered about the purpose of each of the ingredients in your favorite recipes? For example, why is baking powder used in some muffin recipes? How does the baking powder affect how the muffins look, feel, and taste? In this food science project you will use a scientific method to find out! Read more

From Dull to Dazzling: Using Pennies to Test How pH Affects Copper Corrosion

Science Fair Project Idea

Scientific Method

Pennies are bright and shiny when they are new, but become quite dull with time. What causes such a drastic change? Oxygen in the air combines with the copper in the penny to form copper oxide, which makes the penny look dull and dingy. You can make the pennies look like new again by soaking them in water that is corrosive enough to strip off the copper oxide layer. It turns out, however, that the same process that makes the pennies shiny has bad consequences when it comes to copper pipes: it… Read more

Comparing the Sweetness of Sugar & Sugar Substitutes

Science Fair Project Idea

Scientific Method

Cake, cookies, pie, ice cream, hot chocolate, lemonade... Yum! What do all these delicious treats have in common? Sugar. In addition to providing sweetness, sugar adds bulk, flavor, and structure to foods. But is it necessary to add sugar to achieve sweetness? Can the same sweetness be achieved using sugar substitutes like artificial or natural sweeteners? In this project, you will test sugar and sugar substitutes and compare the sweetness of each in relation to sugar. In the end, your day will… Read more

Can Baking Soda Substitute for Baking Powder in a Recipe?

Science Fair Project Idea

Scientific Method

There's nothing quite like the smell of fresh-baked muffins for breakfast on a Saturday morning! If you're into baking, you might want to try this project, which will give you insight into some of the chemistry that's going on in your muffin batter. You'll get some practical knowledge about substituting ingredients. Who knows, it may even get you started on the path to some new culinary inventions! Read more

Water to Fuel to Water: The Fuel Cycle of the Future

Science Fair Project Idea

Scientific Method

Solar cells are popping up on rooftops everywhere these days and are a model for clean, renewable energy. Did you ever look at those solar panels and wonder how we can get electricity produced by solar cells when the sun is not shining? It is a great question because solar panels do not produce electricity when it is dark outside. One strategy to overcome this challenge is to store the energy produced by solar cells during the day in the form of a fuel that can be used at a later time. In this… Read more

How Does the Number of Parachutes Affect Terminal Velocity?

Science Fair Project Idea

Scientific Method

Have you ever wondered how astronauts land safely back on Earth? Many spaceships use a small crew capsule with multiple large parachutes to bring the astronauts down to a gentle landing either on the ground or in the ocean. What happens if one or more of the parachutes fails to deploy? Can the astronauts still land safely? Find out as you explore the physics of falling with parachutes in this project. Read more

Build an Arduino Walking Robot

Science Fair Project Idea

Engineering Design Process

Plenty of animals, like dogs and horses, can walk and run on four legs, but what about robots? Sometimes legs are better than wheels—try out this project to design and build your own quadruped walking robot! Read more

How Does the Intensity of Light Change with Distance?

Science Fair Project Idea

Scientific Method

How does the intensity of a light source change as you move away from it? 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. It does not matter if you are talking about a lightbulb or the sun; this law still applies! Read more

Shaping Your Thoughts?

Science Fair Project Idea

Scientific Method

This is an interesting experiment that explores certain aspects of how your brain pays attention. In this project, you'll have to recruit a bunch of volunteers to take a simple test: naming a list of printed shapes. What makes the test tricky is that words will be printed on top of the shapes. The word/shape combination creates the potential for the brain to get conflicting information. Which information is more likely to grab your attention: the shape you are supposed to name or the word just… Read more
