Make an Automatic Evaporative Cooling System

Science Fair Project Idea

Engineering Design Process

You probably know that sweat helps cool your skin on a hot day because of evaporation. But do you think you can use evaporation to cool a building? Evaporative cooling systems could provide a more environmentally-friendly alternative to traditional air conditioning. In this engineering project you will build and try to optimize your own model evaporative cooling system. 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

Make Your Own Wireless Alarm System

Science Fair Project Idea

Engineering Design Process

Have you ever wished you could have an alarm to prevent your little brother or sister from sneaking into your room? How about an alarm to prevent someone from stealing your favorite toy or from taking cookies out of the cookie jar? In this project you will learn how to program your own customized, wireless alarm systems to send you alerts about whatever you want! Read more

Design Your Own Smart LED Lighting System

Science Fair Project Idea

Engineering Design Process

Have you ever had lights turn on automatically when you walked into a room? Have you turned on a light with your voice instead of a switch? Maybe you have even seen lights that change color depending on temperature, ambient sounds, or how close you are to something. In this project you will design and build your own smart LED lighting system that can change colors and react to various things in the room. The possibilities are endless! Check out this page for more LED science projects. 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?

Shed Light on Electric Generators: Do More Coils Generate More Electricity?

Science Fair Project Idea

Scientific Method

The electricity in your home probably comes from a power plant, but did you know that you can actually generate your own electricity? Wondering what it would take to light up a small light? This is your chance! In this electronics science project, you will build your own electric generator and investigate how to light up not just one, but two lights. Read more

Build an Automatic Dog (or Cat) Treat Dispenser

Science Fair Project Idea

Engineering Design Process

Does your dog get bored when you are not home? Do you ever toss them a few treats right before you head out the door? What if you could keep them busy by automatically dispensing treats throughout the day? What about training them to sit in a certain place or even press a button by automatically rewarding them with treats? In this project you will build your own automatic dog (or cat, or other pet) treat dispenser that you can customize to react to different sensors. Read more

Monitor Plant Health with a Color Sensor

Science Fair Project Idea

Engineering Design Process

Do you have a garden or houseplants? What about living on or a near a farm? How often do you check your plants' leaves for discoloration? What if you could build a robot to check for you, and warn you if your plants are getting sick? In this project you will learn to use a color sensor to identify different colors on leaves, which can give you a warning about problems like pests, diseases, or nutrient deficiency. Get ready to automate your gardening! Read more

Measuring Magnetic Fields

Science Fair Project Idea

Scientific Method

Have you ever noticed how magnets appear to have no effect on each other when they are far apart? Then, when you slowly move them closer together, you will start to feel a gentle pull until they suddenly snap together? How exactly does the strength of a magnet change with distance, and how would you measure it if you wanted to find out? In this project you will build a circuit that can measure the strength of a magnetic field and see how the field strength changes with distance. Read more

Build a Model Planetary Lander with micro:bit

Science Fair Project Idea

Engineering Design Process

How do you make a spacecraft land safely on the Moon or another planet like Mars? It probably helps to know how far away the ground is so you can deploy landing gear, activate a parachute, or fire thrusters to help slow down. In this project you will build your own "lander" vehicle with a sensor that can measure distance to the ground, allowing you to program outputs like blinking lights or an audible alarm. Read more
