How Do Under-Inflated Tires Affect the Difficulty of Riding a Bike?

Science Fair Project Idea

Scientific Method

If you ride a bike, you probably know that you have to occasionally pump up the tires to keep them fully inflated. Over a long period of time, the tires slowly leak air, so their pressure will decrease. Have you ever noticed that it is actually harder to ride a bike when the tire pressure is too low? This is because the tires are a big factor in the rolling resistance of the bike. In this sports science project, you will measure how tire pressure affects the force required to move a bike. How… Read more

Write Your Own Calculator Program

Science Fair Project Idea

Engineering Design Process

When you need a calculator, what do you use? A physical calculator? An app on your phone? A web browser? What features does the calculator have? Does it just do basic arithmetic (addition, subtraction, multiplication, and division)? Can it do other mathematical functions, like square roots or exponents? Can you use parenthesis? Does it have a backspace button? That is a lot to consider for a seemingly very simple device or program! For a computer science project, can you write your own… Read more

Winglets in Wind Tunnels

Science Fair Project Idea

Scientific Method

Winglets are the short vertical "fins" at the wingtips of some airplanes. Have you ever wondered why they are there? If you have access to a wind tunnel, you can build model airfoils with and without winglets and see for yourself. If you're really ambitious, you can also build your own wind tunnel. Read more

Upstairs, Downstairs: Turning on a Light from Two Places

Science Fair Project Idea

Scientific Method

Maybe somewhere in your home there's a long hallway or a stairway with a light that you can turn on from either end. It's a nice convenience, but did you ever wonder how it's wired up to work that way? The goal of this project is to build a similar circuit with switches, flashlight batteries and a flashlight bulb (obviously, household circuits are not safe to experiment with). You'll need to understand the difference between connections made in series and connections made in parallel in an… Read more

HAMing It Up with the Astronauts

Science Fair Project Idea

Scientific Method

Have you ever wished you could talk to an astronaut on board the International Space Station? You're probably thinking "yeah, like NASA would ever let you do that!" Actually, they will! The International Space Station (ISS) is equipped with its own HAM radio station. The ISS HAM radio station allows astronauts, cosmonauts, and space mission specialists from different nations who are on board the space station to talk to people back home on Earth. Anyone with an amateur radio license is… Read more

Build an Autonomous Arduino Robot with Bump Sensors

Science Fair Project Idea

Scientific Method

Mechanical switches are common in many machines and robots. They can be used to detect when a button is pushed, when a door is open, or a low-speed collision when two objects bump into each other. Switches can act as "bump sensors" on a simple robot to help it detect when it hits an obstacle. The robot can use this information to navigate around obstacles and avoid getting stuck. Can you build and program a robot that can drive around your house while using bump sensors to avoid obstacles? Read more

Use Sewable Circuits to Make Cool Costumes and Accessories

Science Fair Project Idea

Engineering Design Process

Do you want to add color-changing lights to your own clothing, costume, or fashion accessory? What about making the lights flash, or adding sensors to make them automatically react to things like temperature or motion? You can do it all with sewable circuits, also called wearable electronics, that let you sew circuit parts directly into fabric. You can make anything from a basic circuit with a few LEDs up to a programmable, Arduino-compatible circuit with multiple sensor inputs and multiple… Read more

Game of Life

Science Fair Project Idea

Scientific Method

The Game of Life is the invention of the mathematician John Conway. It is a cellular automaton, consisting of a grid of squares that turn "on" or "off" depending on simple mathematical rules that involve neighboring squares. Depending on how the grid is first set up (i.e., the initial conditions), various interesting patterns appear. Can you write a Game of Life program in a programming language of your choice? If you are new to programming, check out these resources from the Raspberry Pi… Read more

What's the Fastest Way to Sort a List?

Science Fair Project Idea

Scientific Method

Imagine that you have a list of names of all the people in your class. Someone asks you to put them in alphabetical order. How would you go about doing it? Would you first go through the entire list and look for all the "A" names? Then go through it again and look for all the "B" names, and so on? Do you think going through the list over and over again for each letter would be inefficient? What if you had hundreds, thousands, or even millions of names? How would you ever alphabetize them… Read more

Build a Reed Switch Motor

Science Fair Project Idea

Scientific Method

Motors are used in many things you find around your house, like your refrigerator, coffee maker, and even a lawn mower. In this electronics science fair project, you will get to build a simple motor, using a kit, and then test how the number of batteries (amount of voltage) used to power the motor affects its performance.
