Build a Gauss Rifle!

Science Fair Project Idea

Scientific Method

What can you do with magnets and ball bearings that makes a lot of noise? Why, build a magnetic linear accelerator, called a Gauss rifle, of course! Now, this magnetic accelerator is not a weapon, but a way for you to learn a lot more about physics concepts, like momentum. In this physics science project, you will investigate how far a ball bearing launched by a Gauss rifle will fly, depending on how many magnetic acceleration stages are in the setup and the ball bearing's initial velocity.… Read more

Build a Haptic Glove with Arduino

Science Fair Project Idea

Engineering Design Process

Have you ever used a video game or virtual reality (VR) controller that vibrates? The controller might vibrate when your character gets hit or when you crash in a racing game. This vibration provides additional information to your senses to help you understand what is happening in the game. What if you could feel these vibrations at different points on your skin through something you wear, like a glove? In this project, you will learn how to build and program your own customized glove with the… Read more

Build a Helping Hand

Science Fair Project Idea

Engineering Design Process

The human body is an impressive piece of machinery, and your hands are no exception. With some training, they can perform delicate and complex tasks like manipulating pens and tools to create art. At the same time, hands have the strength and durability to hold a person's own body weight up on steep rocks. Unfortunately, there is a rapidly growing demand for hand replacements. But fortunately, scientists have studied human anatomy and biology and created human-like hands used as artificial… Read more

Build a Light-Tracking Bristlebot

Science Fair Project Idea

Scientific Method

Sometimes engineers get ideas to build robots from animals in nature. There are robot dogs, robot snakes, robot birds, robot cheetahs, and even tiny robotic insects! In this science project, you will build a robot insect of your own. The robot will automatically drive toward a light source, mimicking a behavior called phototaxis, seen in some insects. You will build your own robot and then make adjustments so it can reliably drive toward a light. Read more

Build a Model Planetary Lander with Arduino

Science Fair Project Idea

Engineering Design Process

Imagine that you need to make sure valuable cargo — like a robot or even human astronauts — can land safely on Mars. How would you do it? In this project, you will build your own model planetary lander using an Arduino. It will use a distance sensor and automatically deploy landing gear before impact. Can you avoid a crash landing?

Build a Motion-Activated Guard Robot (BlueBot Project #1)

Science Fair Project Idea

Engineering Design Process

Do you ever wish you could hire someone to guard your favorite toys, or keep certain people from coming into your room? What if you could make a robot to do it for you? This project will show you how to build a simple security robot controlled by a motion-detecting sensor. When someone comes near your valuables or enters the room, the robot will spring to life and (hopefully) scare them away! 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. Read more

Build a Robotic Arm

Science Fair Project Idea

Engineering Design Process

Robotic arms have many uses, ranging from assembling things in factories to collecting soil samples on Mars to acting as prosthetics (artificial limbs) for humans. If you have ever wanted to build your own robotic arm, this project will guide you through the basics of designing and building a simple one. You can use this design as a starting point to design your own robotic arm and add your own features. Read more

Build a Simple Electric Motor!

Science Fair Project Idea

Scientific Method

When you think of a motor, you may immediately think of a car, but you actually encounter other motors in your home every day. That's right, if you put on clean clothes from the washing machine, ate food from the fridge, or used a fan, you used an electric motor. In this electronics science project, you will make a simple electric motor with two magnets that "talk" to each other. As they interact, they will alternate between "liking" each other (pulling together), and "disliking" each other… Read more

Build a Solar-Powered Car

Science Fair Project Idea

Scientific Method

Do you want to build a solar-powered car? How about enter it in a competition and race it against other people's designs? If so, this is the project for you! These instructions will show you how to get started building a solar-powered car that you can enter in a science or engineering fair. No experience needed. If you want, you can even compete in the Junior Solar Sprint, a regional competition for solar-powered cars. Get more information about your regional competition. Are you a… Read more
