What is the Rate of Leaf Growth Along the Stem?

Science Fair Project Idea

Scientific Method

Leaves grow in a different pattern than stems and shoots. They do not elongate along one axis, but instead spread out over time. Do all regions of the leaf grow equally? You can use markings on different regions of a growing leaf to see if the whole surface grows, or if growth is focused in a particular region, like the veins or edges of the leaf. If you look along a leafy stem, you may notice that leaves at different positions along the stem are different sizes. You can do an experiment to… Read more

What Makes a DNA Fingerprint Unique?

Science Fair Project Idea

Scientific Method

Do you like solving mysteries? In this experiment, you can find out how a DNA fingerprint can help you figure out whodunit. The answer might just be in the "sequence" of events! Read more

What Makes a Good Aerodynamic Design? Test Your Ideas with High-Performance Paper Gliders

Science Fair Project Idea

Scientific Method

You have probably made plenty of regular paper airplanes simply by folding a piece of printer or notebook paper. Have you ever tried making a "high performance" paper glider? These gliders use a different construction technique that involves cutting multiple shapes out of thicker, stiffer paper and gluing them together (this process is called lamination). There are many resources online that can get you started with the art of making high performance paper gliders. See the references in the… Read more

What Makes Ice Melt Fastest?

Science Fair Project Idea

Scientific Method

If you live in a place that gets cold in the winter, you have probably seen trucks out spreading a mixture of sand and salt on the streets after a snowfall to help de-ice the road. Have you ever wondered how this works? This basic chemistry project can give you some clues. Read more

What Makes the Rings of Saturn?

Science Fair Project Idea

Scientific Method

Saturn is a unique planet because of the many beautiful rings surrounding it. How are all of those rings made? Why is each ring unique? Read more

What Modern Microbes Could Survive on Early Earth?

Science Fair Project Idea

Scientific Method

Have you ever wondered how life began on Earth? Or how life could get started on other planets? To help us better understand how life began, many scientists try to figure out what it would have been like to live on early Earth. In this science project, you will try to grow microscopic life that could have survived some of the harsh conditions of early Earth! Read more

What Seeds Do Birds Prefer to Eat?

Science Fair Project Idea

Scientific Method

Are you curious about the birds that live in your neighborhood? Would you like to find out more about them: what they look like close up, what they eat, how they sing? In this project you'll build a bird feeding platform with four separate feeding areas. You'll be able to observe birds at close range, find out what birds inhabit your area, and learn about their seed-eating preferences. So get out your woodworking tools and binoculars, and get ready to see some birds. Read more

What's Going On Behind Those Puppy-Dog Eyes?

Science Fair Project Idea

Scientific Method

Have you ever wondered what goes on in your dog's mind? Even though humans have the benefit of language, trying to understand another person's thoughts can be hard enough sometimes. Your dog can't talk, so how can you find out what its brain is capable of? The obvious answer is to study its behavior. This project will show you some behavioral tests you can use to measure canine I.Q. Read more

What's the Best Container for Elephant Toothpaste?

Science Fair Project Idea

Scientific Method

Check out this video from former NASA engineer Mark Rober, where he sets out to reclaim his title for the world's largest and tallest elephant toothpaste reaction. In the video, he experiments with different container shapes and sizes to determine which will result in the most spectacular reaction. You can turn this into a science project of your own! How do differently sized or shaped containers affect the foaming reaction? Can you find an optimal container that makes the reaction go the… Read more

What's the Best Exposure Time for Sun Print Paper?

Science Fair Project Idea

Scientific Method

Did you know you can make paintings or drawings using sunlight? You can do it by leaving objects on top of special sun print paper until the light creates an imprint of the objects. How does this process work? How long should you leave the paper in the sun to get the best result? What does any of this have to do with the process of making the microchips that power our phones and computers? Try this project to find out! Check out this page for more science projects related to this process. Read more
