Make an Adaptive Switch

Science Fair Project Idea

Engineering Design Process

How could you send a text message without using your thumbs? What about typing on a keyboard or using a video game controller without using your fingers? Due to a variety of medical conditions like cerebral palsy or paralysis from an accident, some people might be unable to easily use their hands and fingers to push small buttons or use joysticks. However, they might be able to use their entire hand to push a single larger button or use another part of their body like their foot or even their… 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

Fear Factor: Using Pulse Rate to Measure Emotion

Science Fair Project Idea

Scientific Method

Oh, were you ever scared! Your heart pounded, your breath rate shot up, your palms got cold and clammy. Fear does that to us. Here's a science project based on roller coaster rides to see if heart rate is an accurate measurement of fear. Are you brave enough to take on this frightfully fun project? Read more

How Do Plants Change the Buildup of Greenhouse Gases?

Science Fair Project Idea

Scientific Method

Global warming is how scientists describe the gradual warming of our global climate. Scientists think that the trend towards global warming can be attributed to the build up of greenhouse gases in the earth's atmosphere from industrialization. Another problem is deforestation, as we remove plants and trees from the environment to meet a high demand for lumber or by clear cutting fields for farming and urbanization. By removing trees from the earth's environment, are we changing how greenhouse… Read more

Water Drops and Sparks! Experimenting with a Kelvin Electrostatic Generator

Science Fair Project Idea

Scientific Method

Water is an interesting thing. We drink it, swim in it, and wash ourselves with it. We can get energy from water by damming it and sending it through a turbine. But did you know that we can use the natural electrical charges present in water and a Kelvin electrostatic generator to create sparks? You can even use a Kelvin electrostatic generator to temporarily light a bulb! Now that is one bright idea! Read more

Water Striders & Surface Tension

Science Fair Project Idea

Scientific Method

Water striders (also called water bugs, pond skippers, etc.) are insects that can hop around on the surface of water (Figure 1). Unlike boats or other floating objects that are partially submerged and held up by the resulting buoyant force, water striders are held up by surface tension. Figure 1. Water striders (image credit Isaka Yoji). You can build your own water striders using thin wire (Figure 2 and summary video). Do some background research about… Read more

Do Males and Females Play the Same Types of Games?

Science Fair Project Idea

Scientific Method

There are many different types, also called genres, of computer and video games, including racing, fighting, sports, adventure, and puzzle games. Do some genres of games appeal more to males and other genres more to females? Survey your classmates and find out in this science fair project! Read more

Can Gaming Help You Score Better in School?

Science Fair Project Idea

Scientific Method

Can computer games be used to educate? Pick a game that incorporates educational material. There are a variety of educational computer games on the market in the areas of math, history, science, and language, as well as many simpler versions free on the Internet. Make up a test based on the subject area covered by the computer game. Have your volunteers take the test before and after playing the game. Does playing the computer game improve people's score on the test? Read more

Using Weather Balloon Data to Map Atmospheric Temperature

Science Fair Project Idea

Scientific Method

Snow-capped mountains make a picturesque scene, especially in summertime when the peaks are in such contrast to the warmth below. This project shows you a way to see how temperature changes with altitude using data collected twice daily from weather balloons. Read more

Study Bottle Rocket Performance with Electronic Sensors

Science Fair Project Idea

Scientific Method

Rocket design and operation is a fascinating field and analyzing the flight path provides insight into the rocket's performance. In this project, you will take measurements of the flight path to evaluate how a change in the rocket design or launch procedure impacts the rocket's performance. Initially, while the bottle rocket expels water (or the rocket expels exhaust), the rocket gets a boost. This push is referred to as thrust and projects the rocket forward. Earth's gravity pulls the rocket… Read more
