Bits, Bytes, and Bases: Write a JavaScript Binary/Decimal/Hexadecimal Converter

Science Fair Project Idea

Scientific Method

This is a challenging first computer science project. You'll learn the basics of how digital devices can represent numbers using only 0's and 1's, and you'll write a JavaScript program to convert numbers between binary, decimal and hexadecimal notation. Read more

The Process of Soft-Boiling an Egg

Science Fair Project Idea

Scientific Method

Sometimes on a busy day, it is hard to get things done. The rush to get things done can start first thing in the morning, when you are so busy getting ready and gathering your homework, that you barely have time for breakfast. It takes time to get a nutritious meal ready. But, eggs are a perfect choice for breakfast because they can be cooked quickly and in many different ways. A soft-boiled egg is a choice that many people make. They like the way the thickened, tasty yolk coats their hash… Read more

Mean & Green: Fruit & Vegetable Hardening

Science Fair Project Idea

Scientific Method

When you open a can of green beans, have you ever wondered why the beans are not mushy, or more like a puree? Canning requires boiling the beans for a long period of time to kill bacteria, so why don't the beans fall apart into small pieces? Some fruits and vegetables—like cherries, apples, potatoes, sweet potatoes, beets, carrots, beans, cauliflower, and tomatoes—have the ability to undergo hardening, or firming of their plant tissues. A special enzyme, called pectin methyl… Read more

Cha-cha-cha by Latitude

Science Fair Project Idea

Scientific Method

You probably know that where you live on Earth affects your weather. If you live in a far northern or far southern latitude, you experience colder temperatures than people who live near the equator at latitudes close to zero. Your latitude on Earth affects many aspects of your culture, like how you dress, what kind of house you live in, what foods you eat, and even how your day is structured: what time you go to school, to dinner, and to sleep. Some cities at latitudes closer to the equator,… Read more

Camera Lens Testing

Science Fair Project Idea

Scientific Method

Do you ever use the manual camera settings when taking pictures with your phone? Does your phone have more than one camera lens? This project is a great way to learn more about your phone's camera(s) and how to take better pictures. You can also do this project with a traditional point-and-shoot camera or another camera like a DSLR. Read more

Eco-Friendly Squishy Robots

Science Fair Project Idea

Scientific Method

In our introductory VoxCAD project, you were challenged to use the VoxCAD software to design the fastest possible robot using different materials. However, we did not ask you to think about one big thing — efficiency. It is great to design a robot that is very fast, but what if it also consumes a lot of energy? Engineers must consider this when designing robots in the real world — robots that use more energy to move will drain their batteries faster, which can be a problem. This is… Read more

Gamers: Myth or Man?

Science Fair Project Idea

Scientific Method

Male or female? Fat or skinny? Outgoing or quiet? What is your stereotype of a "gamer"? Do your friends have the same mental picture of gamers? How about your parents? This science fair project will help you examine whether the stereotypes of "gamers" actually matches the reality of who plays video games. Read more

What's the Best Method to Communicate Data Graphically?: An Experiment in Visual Perception

Science Fair Project Idea

Scientific Method

Graphical methods of data presentation are a key feature of scientific communication. This project will get you thinking about how to find the best way to communicate scientific information. Read more

Decisions, Decisions: Judging a Book by Its Cover?

Science Fair Project Idea

Scientific Method

This project challenges you to think like a politician (and a scientist!), and try to ascertain what factors are most important as individuals make their decision on how to vote. For example, is it what is being said, or who is saying it? Read more

Candy Confusion: Can Small Children Mistake Medicine for Candy?

Science Fair Project Idea

Scientific Method

Many medicines come in bottles with special child-proof caps so that small children can't accidentally open the bottle and eat the pills. To a small child who can't read the label, the pills might look just like candy. What cues do we use to tell the difference between medicine and candy? At what age can we tell them apart? This project can show you how to find out. Read more
