How Food Supplements Affect Weight Gain of Juvenile Mice
Science Fair Project Idea
Scientific Method
As your mom and dad always tell you, a healthy diet is important to good health. This project is designed to see what happens to mice when they are allowed to load up on sugary snacks. Do you think that they will gain excess weight? Do you think that the mice will regulate their own intake and maintain a 'healthy' diet? You can try this project and find out for yourself. Read more
How High Can You Throw a Baseball? A Tennis Ball? A Football? A Golf Ball?
Science Fair Project Idea
Scientific Method
How high can you throw different types of balls, like a golf ball, a basketball, and a football? Would one of them go higher than the others? Do factors like mass, shape, and volume influence the final height? You can measure the approximate maximum height a thrown ball reaches by measuring the time it spends in the air. To do this project, you'll need at least one ball and a helper with a stopwatch. Your helper should start timing just as you release the ball, and stop right when the ball… Read more
How Long Does It Take to Fry a Diode?
Science Fair Project Idea
Scientific Method
If you have ever built an electronic circuit with a soldering iron, you know that the component leads get hot. How much of that heat gets into the device you're soldering? This project shows you how you can use a silicon diode as a temperature sensor to find out. Read more
How Long Will My Sleepy Yo-yo Sleep?
Science Fair Project Idea
Scientific Method
Sometimes, simple toys can be quite complicated. Take the yo-yo. It's a fun toy and there is nothing simpler than a string wrapped between two connected disks. But there's a lot of physics that makes a yo-yo work. In this science fair project, learn more about how and why a yo-yo works. You will investigate the effect of string length on the yo-yo's "sleep" trick time. If people ask why you've got a yo-yo with you all the time, tell them that while it looks like you're just having fun, you're… Read more
How Many Cranks Does It Take to Power a Hand-Cranked Radio?
Science Fair Project Idea
Scientific Method
If you lose power, you can probably still access the internet and read the news with a cell phone. But what if the power goes out for so long that your phone battery dies, or if cellular service also goes down? How would you get news from the outside world? In emergencies, you can use a hand-crank radio, which is powered by manually turning a crank. But just how much power do you get when you turn the crank? How long will the radio stay on before you need to charge it again? Try this project to… Read more
How Many Letters?
Science Fair Project Idea
Scientific Method
Can you remember all of your ABC's? Computers need to "remember" letters too. Every time we use a computer to write a story, the computer needs to "remember" the letters in the story by saving them to the computer's memory as a file. In this experiment find out how much memory it takes for the computer to "remember" a series of letters. Read more
How Much Do Different Pet Species Eat Compared to Each Other?
Science Fair Project Idea
Scientific Method
Are you in charge of feeding your family pet? How much food do you think your pet eats compared to other kinds of pets? After adjusting for your pet's body weight, you might be surprised how it will compare to other kinds of pets. What type of pet do you think will eat the most for its body weight? Read more
How Much Mass Is Needed to Make a Body Round?
Science Fair Project Idea
Scientific Method
Use your Internet sleuthing skills to learn about solar system objects. Create a table of measurements of moons and asteroids in order to determine if there is a size threshold for roundness. A good source of information would be an online guide such as The Nine Planets (Arnett, W.A., 2006). You'll find information about planetary satellites, including dimensions and accompanying pictures. From the pictures, classify the satellites and asteroids according to how round they are. Can you think of… Read more
How Much Weight Can Your Sandcastle Hold?
Science Fair Project Idea
Scientific Method
Do you think a sandcastle can support a brick? How can you change a sandcastle to make it support more weight? Find out in this fun science project! Read more
How Much Worm Is a Worm?
Science Fair Project Idea
Scientific Method
Worms are slimy, wiggly, and gross. But did you know that they have many unique abilities? One of the neatest things that worms can do is regenerate, or re-grow, parts of their body. After a piece of a worm is cut off, it can grow back with all of the necessary new parts. How much of a worm can you cut off and still get regeneration? Is one end of the worm better at regenerating than the other? See if you can make heads or tails of this wiggly problem! Read more
