Identify Road Signs with Machine Learning
Science Fair Project Idea
Engineering Design Process
Driverless cars use machine learning, a type of artificial intelligence, to identify road signs and other things they encounter on the road, like pedestrians and other vehicles. In this project you will take your own pictures of different types of road signs and use machine learning to identify the signs using a free online tool (no programming is required). You will then attempt to improve your machine learning model so it can identify signs in a variety of environments. Read more
Wildfire Simulator
Science Fair Project Idea
Scientific Method
Wildfires can devastate communities, destroying homes and creating smoke that can affect air quality over huge areas. A wildfire could start from a natural cause like a lightning strike, or humans being careless with cigarette butts or campfires. What if you could predict how a wildfire will spread to help give people an advanced warning to get out of harm's way? Can forest management techniques like controlled burns—intentionally setting smaller, more controlled fires—help reduce… Read more
Make a Color Detector App to Help Colorblind People
Science Fair Project Idea
Engineering Design Process
Do you know anyone who is colorblind, or are you colorblind yourself? What if you could carry a device in your pocket that could identify colors for you? Many people already carry around the device they need to do this - a smartphone! Since phones have built-in cameras, you can make an app that uses the camera to identify colors. In this project you will use a program called MIT App Inventor that makes it easy for anyone, even with no programming experience, to design your own mobile app.  Read more
Happy or Sad? Use Artificial Intelligence to Classify Faces
Science Fair Project Idea
Engineering Design Process
Do you think artificial intelligence (AI) is too complex to use? Think again! In this project, you will use AI to teach a web-based tool to classify happy and sad faces, or other objects, poses, or sounds. This experiment requires no coding skills; instead, you will need curiosity, creativity, and a critical eye. Why not give it a try yourself? Read more
The Point of a Parabola: Focusing Signals for a Better Wireless Network
Science Fair Project Idea
Scientific Method
Have you ever been annoyed by poor Wi-Fi reception for your phone, tablet, or laptop? Do you wish there was something you could do about it? In this project you will learn how to build a parabolic reflector that you can attach to the antenna of a regular wireless router to help boost its signal. Read more
Predicting How Urban Wildfires Will Spread
Science Fair Project Idea
Scientific Method
Urban wildfires can cause devastating loss of life and property. Can we save lives by predicting how and where these fires will spread? What protective measures can we take to save buildings from the fires? In this project you will use a computer model to simulate how wildfires spread in populated areas, and experiment with different protective measures to try and save houses from burning.  Read more
Make a Medical Alert Fall Detector
Science Fair Project Idea
Engineering Design Process
Have you ever wondered what someone would do if they fell, got hurt, and could not get up on their own? What if they were home alone and could not reach a phone to call for help? Or, what if they lost consciousness - is there any way to automatically detect that they fell and needed help? In this project, you will program your own fall detector, a device that can automatically detect when someone has fallen over, then sound an alarm or even send a message to someone else. Devices like these are… 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
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
Make a Mood Tracker
Science Fair Project Idea
Engineering Design Process
How do you feel right now? Do you remember how you felt a few hours ago? How about yesterday or last Wednesday? What if you could track your emotions throughout the day and use this information to help improve your mood and well-being? In this science project, you will program a simple, pocket-sized device that you can carry around with you to log your feelings whenever you want or on a specific schedule.  Read more
