Solid Ground? Measuring Soil Bearing Capacity

Science Fair Project Idea

Scientific Method

Foundations for many types of structures rest on soil. This project shows how you can investigate the bearing capacity of different types of soil. Read more

Build a Water Clock to Show the Drip, Drip, Drip of Time

Science Fair Project Idea

Scientific Method

What are some of the ways we keep track of time? We have alarm clocks, wristwatches, and cell-phone clocks, to name a few. Just a few hundred years ago, our ancestors did not have any of these conveniences, yet they found ways to tell time. How? By using devices such as water clocks. In this science project, you will follow in the footsteps of early engineers and build a water clock that tracks time for three hours. Read more

Strength of Glues

Science Fair Project Idea

Scientific Method

Try gluing wood together with different types of glue, e.g.: regular white glue, yellow wood glue, cyanoacrylate (super glue), and Liquid Nails. Glue a short piece (5-8 cm) to the center of a longer piece (15-30 cm). After the glue has dried for the recommended time, drill a small hole through the center of the joint, big enough to pass through a piece of coat-hanger wire. Cut a length of coat hanger wire, pass it through the hole, and twist the ends together to form a loop. Place the ends… Read more

Preventing SQL Injection Attacks

Science Fair Project Idea

Engineering Design Process

How many websites do you have accounts with that store personal information like your name, email, phone number, or mailing address? If the people running these websites are not careful, hackers could gain unauthorized access to, and even change or delete, your information. They can do this using something called SQL injection, which involves entering malicious code into text fields on a website. In this project you will learn how SQL injection works and figure out how to prevent it. Read more

Experiment with Making Gels

Science Fair Project Idea

Scientific Method

Chances are, you have several materials around your house made of gelatinized materials. Gels are used in all kinds of products and materials: pudding, diapers, insoles, packaging, ice cream, toothpaste, and many more. In this project, find out how gels are made and how they can be adjusted from firm to soft by changing the ingredients. Read more

Simple Circuit Logic with Switches: An Electric Puzzle

Science Fair Project Idea

Scientific Method

Here's a puzzle you may have heard before which you can build as a simple electric circuit. First, the puzzle: a farmer is traveling to market with his cat, a chicken and some corn. He has to cross a river, and the only way to cross is in a small boat which can hold the farmer and just one of the three items he has with him. The problem is, he has to be very careful about what he chooses to leave behind at any time. If the cat and chicken are left alone, the cat will eat the chicken. If… Read more

Detecting Exoplanets Using Transit Photometry—Advanced

Science Fair Project Idea

Scientific Method

In astronomy, a transit (or astronomical transit) is a phenomenon when a celestial body passes directly between a larger body and the observer. As viewed from a particular vantage point, the transiting body appears to move across the face of the larger body, covering a small portion of it. The word "transit" refers to cases where the nearer object appears smaller than the more distant object. Cases where the nearer object appears larger and completely hides the more distant object are known as… Read more

Creating a Video Game for Players with Visual Impairments

Science Fair Project Idea

Engineering Design Process

Do you enjoy playing video games? Do you like the challenge of reaching a difficult game level and scoring lots of points? Video games include many graphic elements that are great to watch, but did you know that not only sighted people enjoy video games? Blind and visually impaired players can also play video games by relying on sound cues — the pings, pops, bangs, and bursts of music that make a game fun or exciting. When building a game that will be accessible to differently abled… Read more

Build Your Own Dobsonian Telescope

Science Fair Project Idea

Scientific Method

For an advanced science fair project, you can build your own telescope and learn how to use it to make observations of the night sky. Can you make your own observations to determine the orbital period of Jupiter's major moons? The Dobsonian telescope, first built and popularized by astronomer John Dobson, is considered to be the best bang-for-your-buck if you want to build a good amateur telescope. The smaller the telescope's aperture the less expensive to build, but also the less… Read more

Engineer a Cell Phone Stand

Science Fair Project Idea

Engineering Design Process

Look around you. What types of objects do you see in the room? Furniture, lights, a computer, a fan, pencils, books, etc.? Where did they come from? Odds are you did not build them yourself. You or your parents probably bought them at a store. Before that, they were built in a factory somewhere. And even before that, they were probably designed by engineers. You might think of engineers when you think of complex machines like rockets or huge structures like bridges, but engineers also design… Read more
