Science Fair Project Idea

Scientific Method

Have you ever wondered why geese fly in a V-formation? In this science fair project, you will build a wind tunnel to test how the formation of birds in flight actually affects their flight efficiency. Read more

Energy Savings with LED Lighting

Science Fair Project Idea

Scientific Method

Global warming, climate change, melting ice caps—these are all big events that have an impact our environment. What can we do to help reduce the impact? We can reduce, reuse, and recycle. What can cities do to help? Cities can eliminate waste by saving energy. Cities around the world are switching from incandescent traffic signals to LED traffic signals to save energy and money. That's because LEDs are more efficient than incandescent lamps, which means that LEDs produce more light… Read more

Evolution of Friendship Groups Over Time

Science Fair Project Idea

Scientific Method

This project asks the question "How do friendship groups change over time?" The results may support inferences about how "people skills" develop. What types of changes would you expect to see? Do you expect friendship groups to grow larger over time? Do you expect that individuals will belong to more, less or about the same number of friendship groups as they get older? Do you think there will be more or less exclusivity among groups (and how would you measure such a concept)? Do you… Read more

Build Your Own Helio Tracker—a Self-powered Mechanical Sunflower that Turns with the Sun

Science Fair Project Idea

Scientific Method

The amount of energy produced by most photovoltaic (solar) panels is limited, due to their immobility. However, when photovoltaic panels track the movement of the Sun, their efficiency increases significantly. This can be done with computers and sophisticated electronics, but for rural or wilderness settings, a "low-tech" sun tracker would be beneficial. A solution exists in nature: the sunflower. The challenge in this science fair project is to design and build a device that imitates the… Read more

Biodiesels: Converting Oil into Clean Fuel

Science Fair Project Idea

Scientific Method

Most of the energy and fuel that we use in the United States is derived from burning fossil fuels. Fossil fuels are the remains of plants and animals that lived hundreds of millions of years ago. Examples of fossil fuels include coal, petroleum oil, and natural gas. Burning coal releases 21.3 gigatons of carbon dioxide— a greenhouse gas that may be responsible for global warming and climate change—into the air in one year. About half of this amount is absorbed by natural processes… Read more

Less Cowbell! The Unconstrained Truth About Constrained-Layer Damping

Science Fair Project Idea

Scientific Method

Noise is everywhere. From the clanking of a cowbell to the din of the lunchroom, we are surrounded by noise. Sometimes there's no way to get away from it, but there is a way to deal with it—constrained-layer damping. By simply creating a layered sandwich of somewhat flexible materials, what was once a noisy cowbell can become a "noise blanket." This science fair project shows you how to transform a noisy piece of metal into a sound-muffling constrained-layer damper. You'll record the… Read more

Build a Wearable Device Using an Arduino to Keep Astronauts Safe on Mars

Science Fair Project Idea

Engineering Design Process

Astronauts on Mars missions must be protected from hazardous environments, like steep cliffs, rocky terrain, and extreme temperature variations. How can geofencing help? In this project, you will design a system that uses geofencing technology coupled with biosensors to ensure astronaut safety. The system will create a virtual boundary around astronauts, providing alerts if they approach dangerous areas or leave designated safe zones, or if their vital signs fall below a certain threshold. Can… Read more

Build an Arduino Robot

Science Fair Project Idea

Engineering Design Process

The Science Buddies Bluebot Kit contains parts to build four different robots: A motion-activated robot that uses a passive infrared (PIR) sensor A light-tracking robot that uses photoresistors A line-following robot that uses infrared emitter-detectors An obstacle-avoiding robot that uses bump sensors However, in each project, the sensors are hard-wired to control the robot's motors. This allows the robot to steer left and right based on input from two sensors, but it does not allow the… Read more

Crystal Ball Math: Predicting Population Growth with Models

Science Fair Project Idea

Scientific Method

When is an animal considered endangered? When will it become extinct? What happens when a population has reached the limits of its resources? What happens to a population when a habitat changes? These are some of the questions population biologists try to answer. They use population models, created from math equations, to predict what will happen to a population over time. If you want to see how modeling is done and make some predictions of your own, you certainly won't need a crystal… Read more

Digital Image Processing

Science Fair Project Idea

Scientific Method

Students who are mathematically inclined can use the student version of a program like MatLab or Mathematica to convert a digital image into numbers, then perform operations such as sharpening or special effects. This is a great way to learn about image processing algorithms. Read more
