Fight Flooding and Pollution with...a Garden?!
Science Fair Project Idea
Scientific Method
What looks pretty, stops flooding, and helps fight pollution? A rain garden! Find out how by building and testing your own miniature rain garden in a plastic bottle. Read more
Spice Up the Power of a Microbial Fuel Cell with a Dash of Salt
Science Fair Project Idea
Scientific Method
Generating power from mud sounds like science fiction, but it is actually real science, and a promising source of alternative energy. Topsoil is packed with bacteria that generate electricity when placed in a microbial fuel cell. Because such bacteria-laden soil is found almost everywhere on Earth, microbial fuel cells can make clean, renewable electricity nearly anyplace around the globe. They are an up-and-coming technology that scientists and engineers are working to make even more… Read more
Make a Pomodoro Study Clock
Science Fair Project Idea
Engineering Design Process
The Pomodoro technique is a popular study method consisting of alternating study sessions and breaks. In this engineering project you will build your own customized Pomodoro timer or clock using an Arduino. In addition to displaying the time, you can use your clock to display messages or get the user's attention using lights, sound, or even moving parts. Can you work more efficiently with a Pomodoro timer at your side? Build one and find out! Read more
Modifying a Car for Better Aerodynamics
Science Fair Project Idea
Scientific Method
Have you ever seen those cool wind tunnel pictures of cars with streams of smoke blowing over them? You do not need access to a wind tunnel to do a car aerodynamics science project! In this project you will use cheap, readily available materials—tape and yarn—to visualize airflow over a car. You will examine how you can affect the airflow over the car by making changes, like adding or removing accessories or making body modifications out of cardboard and duct tape. Maybe you can… Read more
Use Super-strong Magnets to Make a Simple Motor
Science Fair Project Idea
Scientific Method
In this science project, you will build what might be the world's simplest motor. It has just four basic parts: magnets, a battery, a screwdriver, and a short piece of wire. It takes only minutes to assemble, but it provides a wonderful device to explore how electricity and magnetism combine to produce a fast-spinning motor. Read more
Design Your Own 3D Printed Optical Illusion
Science Fair Project Idea
Engineering Design Process
The "impossible arrow" is an amazing optical illusion: an arrow that always seems to point to the right, even when you rotate it 180°. If you place the arrow in front of a mirror, however, its reflection points to the left! How does this illusion work? Can you design your own "impossible" shapes? Try this project and find out! Read more
Build a Fuzzy Companion Robot
Science Fair Project Idea
Engineering Design Process
Snuggling a dog or cat can make you feel better even when you are not lonely or sick. Therapy and companion animals are also used for patients in health care settings, but sometimes you cannot always have access to a real live animal. Can a robot serve the same purpose? Find out in this project when you add an Arduino to a stuffed animal to build a purring companion robot. Read more
Explore How Chromatography Can Unmix Mixtures
Science Fair Project Idea
Scientific Method
Did you know that mixtures can be unmixed? Chromatography is an analytical technique in chemistry to separate mixtures and identify each of its individual compounds. In this project, you will separate ink dyes found in different markers using a strip of paper, chalk and different liquids. By comparing different chromatography substrates and solvents, you will learn how different attractive forces between substances can affect the separation of a mixture into its individual components. Read more
Build an Arduino Strobe Light for the Stroboscopic Effect
Science Fair Project Idea
Engineering Design Process
The Science Buddies project Build a Levitating Water Fountain with the Stroboscopic Effect shows you how to illuminate a dripping stream of water with a strobe light to make it look like the drops are hovering in mid-air. If you have not already, read the background section of that project and watch the following two videos. Make sure you understand frequency, period, and duty cycle before you proceed with this project. The project has you use a strobe light app on your phone. The advantage… Read more
Ion Thruster: Build an Ion Wind Rotor
Science Fair Project Idea
Scientific Method
Ion thrusters, also called ion engines (Figure 1), are a type of electrically-powered spacecraft propulsion. While they provide very low thrusts (and thus low accelerations), they can do so for very long periods of time using a very small amount of fuel. So, while not appropriate for escaping Earth's gravity like chemical rockets which are less efficient but generate higher thrusts, they are useful for deep-space probes or making small adjustments to satellite orbits. You can read more about… Read more
