Porosity and Particle Size
Science Fair Project Idea
Scientific Method
Often, when we think of something that is solid we think about rocks. But in reality, rocks have tiny holes of air inside them. This is called porosity. In this science project you can find out what it means to be "solid as a rock!" Read more
How to Balance Anything
Science Fair Project Idea
Scientific Method
Ever wonder why it is harder to keep your balance with a heavy backpack on? Or why it is difficult to make a toddler's sippy cup tip over? Maybe you are the kind of person who wonders about circus balancing acts and would like to learn how to ride a bike on a rope. Or perhaps you want to know how to make your toy car less prone to toppling over when racing through a sharp curve. In this science project you can learn about balance using marshmallows, skewers, and toothpicks. Sticky, yummy… Read more
The Bouba-Kiki Effect
Science Fair Project Idea
Scientific Method
Have you ever wondered if some shapes have certain "sounds" to people, even if they have different native languages? For example, does everyone match certain physical characteristics, like sharpness or roundness, with certain sounds? Are there certain human sounds with meanings that can cross the language barrier? In this science project you will investigate this by testing the Bouba-Kiki Effect—will it turn out that abstract visual properties can be linked to sound? Read more
Liver Stinks!
Science Fair Project Idea
Scientific Method
Sometimes science can be really messy or use pretty disgusting ingredients. That is what it takes to understand how the world works, even if the experiment isn't pretty. Do you like chemical reactions that stink and ooze foamy bubbles? Do you think it sounds fun to make a super gross liver smoothie? Then this is the experiment for you! Read more
Knock Your Blocks Off: The Mechanics of Carnival Games
Science Fair Project Idea
Scientific Method
"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
Give It a Lift with a Lever
Science Fair Project Idea
Scientific Method
Did you know that you can lift an object that's heavier than you are? Just use a lever! In this science project you'll build a tabletop lever and measure how much effort it takes to lift an object using it. Read more
Make a "Whirlybird" from Paper
Science Fair Project Idea
Scientific Method
Have you ever seen a maple seed twirling as it falls through the air? In this project you will build something that behaves similarly called a whirlybird. Will your whirlybird be able to stay in the air as you add paper clips as weights? Try this project to find out! Read more
Yeasty Beasties
Science Fair Project Idea
Scientific Method
While looking at a package of dry yeast it is hard to believe that the package has organisms in it that are alive. But add the right ingredients and presto, the mixture becomes a bubbly, oozing, mess of life! What are the right ingredients? What does that yeast need to become active? Do this science project and figure it out for yourself! Read more
The Moon and Tides
Science Fair Project Idea
Scientific Method
Have you ever wondered what causes the tides in Earth's oceans? In this astronomy project, you will discover the answer for yourself! You will investigate how the Sun and Moon control tides in Earth's oceans. Read more
Why Video Game Characters Look Better Today
Science Fair Project Idea
Scientific Method
When you picture video games, you probably picture realistic three-dimensional figures, a lot of color, and a lot of detail, right? Those descriptions do not really describe video games from the early 1980's. So why do video games today look better than video games from the 80's? One major change between then and now is the number of pixels, or dots on the screen, used to represent video game objects. When Nintendo® first introduced the Super Mario Bros game for the Nintendo Entertainment… Read more
