Science Fair Project Idea

Scientific Method

We encounter an amazing array of colors every day, from the greens of plants and the many colors of their flowers, to the pinkish blue of a sunset, to the artificial coloring in beverages. How do we perceive all of these colors? When light hits an object, some of that light is absorbed by the object, and the light that is not absorbed is what we see. In this science project, you will build a simple spectrophotometer from a cell phone and use it to investigate how visible light is absorbed by… Read more

Build an Arduino Walking Robot

Science Fair Project Idea

Engineering Design Process

Plenty of animals, like dogs and horses, can walk and run on four legs, but what about robots? Sometimes legs are better than wheels—try out this project to design and build your own quadruped walking robot! Read more

How Electricity Changes pH in Salt Solutions

Science Fair Project Idea

Scientific Method

You have probably heard the saying that "water and electricity don't mix." Well, in this chemistry science fair project you will mix them, to create two solutions, one basic and one acidic. The apparatus is very simple, but the chemistry is complex and offers many avenues for exploration. Read more

The Chemistry of Clean: Make Your Own Soap to Study Soap Synthesis

Science Fair Project Idea

Scientific Method

Soap comes in many varieties and forms—from bars to bottles to boxes. The uses for soaps are just as expansive—from cleaning our hands, hair, and faces to a variety of household cleaning jobs, such as dishes or laundry. One thing all these different soaps have in common is their chemical origin; they were all made by mixing fat or oil with a strongly basic solution, such as lye. In this chemistry science project, you will carry out the chemical steps needed to transform coconut oil… Read more

Make Your Own Low-Power AM Radio Transmitter

Science Fair Project Idea

Scientific Method

Have you ever wondered how an AM radio station works? In this project you will learn the basics of how your favorite songs are transmitted by a radio station, by building your own simple AM radio transmitter. You will learn the basics of how a transmitter works, and how you are able to tune to your favorite station and listen to music. Read more

How Bright Is Your Glow Stick? Measure It!

Science Fair Project Idea

Scientific Method

Objects that glow in the dark hold a special place in the imagination of both children and adults. The lights go out at night, but these odd things refuse to disappear. Where does the light come from? Do they work in any climate? In this science fair project, you will make a very simple electronic device to measure the light given off by luminescent materials. The device will be used to study how temperature affects luminescence. Read more

Control Motors with Your Muscles!

Science Fair Project Idea

Engineering Design Process

Have you ever wished you could control your own suit of power armor like Iron Man? What about building a set of Wolverine-like retractable claws? You can get started by using electromyography (EMG) sensors, which can measure the tiny electrical signals generated by our muscles when they contract (Figure 1). You can interface these sensors with a microcontroller like an Arduino and use the output to control LEDs or motors. Getting these sensors to work can be tricky. The electrical signals… Read more

The Design Process: Creating a Stronger Truss

Science Fair Project Idea

Scientific Method

This is an interesting project that explores which geometrical shapes make the strongest bridge truss structures. It is a good introduction to the engineering design process. You'll design three different trusses, and use online simulation software to analyze the distribution of load-bearing forces in each design. Then you'll build and test prototypes of each design. Read more

Hacking the Air Gap: Stealing Data from a Computer that isn't Connected to the Internet

Science Fair Project Idea

Scientific Method

You might think that one sure-fire way to keep your computer safe from hackers is to disconnect it from the internet entirely. But did you know that even without internet, a computer can transmit data using light, sound, vibrations, or even heat? In this project, you will investigate how a spy or hacker can steal data from an "air-gapped" computer that has no internet connection. You can even use a smartphone equipped with a sensor app to demonstrate how the data can be picked up by a nearby… Read more

Motorized Arduino Cable-Driven Spacecraft Motion Simulator

Science Fair Project Idea

Engineering Design Process

How do you practice docking a spacecraft with the International Space Station or landing on Mars? With a room-sized cable-driven spacecraft motion simulator! In this project, you will build your own miniature, motorized version of a full-sized motion simulator scientists are developing that can move model spacecraft around in a controlled manner.
