Science Fair Project Idea
Engineering Design Process
Have you ever wondered about the various types of music in a video game you've played? You may not have paid much attention to the music, but its job was to enhance your gaming experience. In fact, the wrong kind of music can detract from the atmosphere of the game. Can you imagine the music in Mario KartTM playing in Street Fighter®? In a game, music can indicate many different things, such as a special or new event, shift of mood, or the arrival of a character. This kind of music is… Read more

Engineering Design Process
If you live in an area where earthquakes happen, you might be especially interested in this science project. You will learn how to build your own seismograph and how to use it to detect ground motion. Read more
Science Fair Project Idea
Scientific Method
In this science project, you will collect macroinvertebrate samples from multiple points along a body of water, ideally a small creek or stream, and test the pollution burden and biodiversity of small organisms or insects to see if pollution impacts biodiversity. Read more

Are you ready to move beyond paper circuits and squishy circuits? This is a great intermediate circuit project where you will build your own working night-light. And of course, you will have some fun decorating it! Read more
Science Fair Project Idea
Engineering Design Process
When you think about robots, do you think of something made from metal? What if robots could have stretchy, flexible skin just like humans? How would they detect when someone tapped them on the shoulder or something rubbed against their arm? In this project, you will learn how to make artificial robotic skin using flexible rubber with an embedded conductive fabric. You can also connect the artificial skin to a microcontroller and use it to control outputs like LEDs or motors.  Read more

Did you ever wonder what hand sanitizer is made of, or how you can efficiently disinfect your hands or other frequently touched surfaces like doorknobs? Handwashing is still the best way to keep your hands clean, but hand sanitizer is a great alternative for situations where clean water and soap are not available, and you can even use it to disinfect surfaces! Intrigued—try out making a hand sanitizer yourself! Read more

Engineering Design Process
How do you practice docking a spacecraft with the International Space Station or landing on Mars? With a room-sized cable-driven spacecraft motion simulator! In this project, you will build your own miniature, motorized version of a full-sized motion simulator scientists are developing that can move model spacecraft around in a controlled manner.

Scientific Method
Ocean currents have profound effects on the climates of the continents, especially those regions bordering on the ocean. For example, the Gulf Stream (a warm current that goes around the North Atlantic Ocean) is thought to make northwest Europe much warmer than it would otherwise be. Similarly, the California Current is thought to keep Hawaii cooler than other land masses at the same latitude as it. In this ocean science fair project, you will model the behavior of these "rivers" of hot and… Read more

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
Science Fair Project Idea
Scientific Method
Have you ever wondered what causes wildfires and how resources are allocated to prevent their spread? In this science project, you will use machine learning to predict areas of wildfire susceptibility and their intensities. Read more
