Science Fair Project Idea

Scientific Method

Mowing the lawn is hard work, especially on a warm day. Not only do you have to mow the grass, but you also have to dispose of the clippings. Some people add the clippings to a compost pile in their yard, which is a great idea. But did you know that some grasses can be used as a source of energy? In this energy science fair project, you will learn more about a type of energy called biomass energy. You will grow different kinds of grasses and see which type of grass gives you the most biomass,… Read more

Understanding the Emotions Hidden in Words with Sentiment Analysis

Science Fair Project Idea

Scientific Method

Sentiment analysis helps us understand the emotions behind text, such as whether people feel positive, negative, or neutral about a topic. It is useful for analyzing opinions on social media, reviews, or other text data. In this project, you will gather text data on a topic of your choice and use a sentiment analysis tool called VADER (Valence Aware Dictionary and sEntiment Reasoner). Read more

Storytelling Alice: Once Upon a Time in a Computer-generated Land...

Science Fair Project Idea

Scientific Method

The Incredibles, Ratatouille, Up. What do these Pixar films have in common? They are all computer-animated films. While the writers and directors came up with the compelling stories and the kinds of scenes that would best tell the stories, the computer animation experts brought the films to life. In this computer science project, you will easily be able to create your own animated story using a simple computer programming environment called Storytelling Alice. To create your animation, you will… Read more

The Power of Your Eyes: How Vision Affects Balance

Science Fair Project Idea

Scientific Method

Staying balanced might feel simple, but there’s so much more involved than you would think! The way your body balances is actually the result of several body systems working together. Your muscles and joints provide feedback (proprioception) about where your body is in space, your inner ear senses movement and position, and your eyes give you important visual cues about your surroundings. Vision is especially important because it helps your brain judge where you are in relation to the… Read more

Build an Arduino Strobe Light for the Stroboscopic Effect

Science Fair Project Idea

Engineering Design Process

The Science Buddies project Build a Levitating Water Fountain with the Stroboscopic Effect shows you how to illuminate a dripping stream of water with a strobe light to make it look like the drops are hovering in mid-air. If you have not already, read the background section of that project and watch the following two videos. Make sure you understand frequency, period, and duty cycle before you proceed with this project. The project has you use a strobe light app on your phone. The advantage… Read more

Pounding Papyrus: How Ancient Egyptians Made the World's First Paper

Science Fair Project Idea

Scientific Method

It's hard to imagine a world without paper. You wouldn't have things like books, cards, comics, newspaper, construction paper, notebooks, cereal boxes, or that nice sound of shredding wrapping paper on your birthday. There was a time, though, when the only thing people had to write on were slabs of soft, squishy clay. When these slabs dried in the sun, they preserved simple ideas, but they were heavy, like carrying around a load of rocks. Not exactly easy to put in your pocket and carry around.… Read more

Dust Busters: How No-Plow Farmers Try to Save Our Soil

Science Fair Project Idea

Scientific Method

Do you have any great-grandparents who lived through the Great Depression in the United States during the 1930's? If so, they might have stories to tell about terrible dust storms that blackened the skies, from the Midwest to the east coast. Severe drought was a factor in causing this "Dust Bowl" era, but decades of poor farming practices contributed to it, too. In this environmental science fair project, you'll learn about farming methods that help keep dirt from drying up into dust, and help… Read more

Unleash the Power of a Pinwheel!

Science Fair Project Idea

Scientific Method

How do you feel when you ride your bike into a strong wind? Do your legs feel like lead? How about when the wind is at your back? Does that make you feel ready for the Tour de France? In this science fair project, you will investigate how wind-powered devices, like pinwheels, also react in different ways to the direction of the wind. 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

Bristlebot Shape and Motion Tracking

Science Fair Project Idea

Scientific Method

Bristlebots are tiny little robots with no "brain." They are powered by vibrations and move around randomly. Even if there is no brain, can you still influence how they move by changing their design? Find out in this fun robotics project! Read more
