What's the Best Way to Guarantee Fresh Bread?

Science Fair Project Idea

Scientific Method

Have you ever bitten into a slice of bread only to find that it no longer seems fresh? Instead, it has the firm, undesirable texture that comes about when the bread is going stale. Chemically, what happens during the staling process? Can it be reversed (at least temporarily)? Do some background research to answer these questions and then apply those answers to one (or more) of the following experiments to find the optimal state to keep your bread fresh. Experiment 1: What Temperature Keeps… Read more

Digital Photos and Dynamic Range

Science Fair Project Idea

Scientific Method

Digital cameras can be a great way to learn about photography. Most digital cameras today have LCD screens, so you get instant feedback on your photo. If you make a mistake, no problem, you just delete the picture. It's nice that you don't have to worry about the expense and bother of developing film! This project can help you learn to take better pictures. Read more

Image Compression vs. Image Quality: Finding the Best Tradeoff

Science Fair Project Idea

Scientific Method

In this project you'll learn about how digital image files are encoded, and how digital images can be compressed so that the files take up less storage space and can be transmitted more quickly. You will also measure the quality of compressed and uncompressed images, which will give you important insights into the tradeoffs between file size and image quality. 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

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

Dry Spells, Wet Spells: How Common Are They?

Science Fair Project Idea

Scientific Method

Can you remember what the weather was like last week? Last year? Here's a project that looks at what the weather was like for over a hundred years. You'll use historical climate data to look at moisture conditions in regions across the continental U.S. You'll use a spreadsheet program to calculate the frequency of different moisture conditions for each region and make graphs for comparison. Which part of the country has the most frequent droughts? The most frequent periods of prolonged… 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

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

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

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
