Science Fair Project Idea
thumbnail Would you like some sky vegetables for dinner? How about some fresh-cut roof flowers to put in vases in your house? Around the world, rooftops are being transformed into living green expanses. Besides beauty, rooftop gardens have a number of advantages, including growing food and taking carbon dioxide out of the air while releasing breathable oxygen. But can rooftop gardens also keep your house cooler and lower your energy bill? Try this science fair project to find out. Read more

Science Fair Project Idea
thumbnail Have you ever left your bike outside in the rain? If so, you might have discovered unpleasant surprises afterwards—reddish-brown patches, known as rust, and your wheels, brakes, and gears might have stopped working so smoothly. In this chemistry science fair project, you'll learn why rust, a type of corrosion, is a serious problem. You'll also discover that not all rains are the same! Find out which ones can speed up the rusting process. Read more

Science Fair Project Idea
thumbnail Do you want to trick friends and visitors with an amazing optical illusion? In this engineering design project you will learn how to build an infinity mirror,with built-in lights that make the mirror look like a deep tunnel with no end. But pick the mirror up and look behind it, and you will see that it is only a couple of inches thick! Read this project to find out not only how this illusion works, but how to design and build your very own infinity mirror from scratch. Read more

Time Required Average (6-10 days)
Prerequisites None
Material Availability This project will require some specialty materials from hardware and arts and craft stores. See the Materials and Equipment list for details.
Cost Average ($40 - $80)
Safety Adult supervision is required when using any sharp cutting tools or power tools to cut plexiglass. Always wear safety glasses or goggles when cutting brittle materials such as plexiglass. Some tools (in particular, hot glue guns and soldering irons) can cause serious burns. Use these carefully and with adult supervision.
Science Fair Project Idea
thumbnail 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

Science Fair Project Idea
thumbnail Do you like getting something for nothing? Everybody likes getting things for free. How about getting energy and power for free? The Sun sends us free energy every second and all we have to do is collect it. Taking advantage of free energy can reduce our dependence on fossil fuels, which are harmful to our environment. In this science fair project, you will work with a solar panel, which is a collector of free energy, and investigate how varying the angle of the solar panel, and thus the amount… Read more

Science Fair Project Idea
thumbnail Everyone knows electricity can create heat, especially because our electrical appliances tend to warm up when turned on. But wouldn't it be cool to do the reverse — generate electricity from heat? In this science project, you will study why it happens, measure the effect, and then use the phenomenon to build your own device, a thermocouple thermometer, that will enable you to convert heat into electrical energy.

Science Fair Project Idea
thumbnail Many people are surprised to learn that the season's we experience—winter, spring, summer and fall—have nothing to do with the distance of Earth from the Sun. In this science fair project, you will investigate how the temperature on Earth actually depends on the tilt of Earth's axis of rotation. Read more

Safety Minor injury is possible, so be careful when using the heat lamp.
Science Fair Project Idea
thumbnail In baseball, coaches use hit charts to track the results of every hit each player makes, giving a measure of the player's performance. Have you ever wondered what things affect where a baseball goes when a player hits it with a bat? In this project you will set up an experiment to hit a ping pong ball in a controlled manner using a toy catapult, then learn about the physics of baseball by making your own hit chart. Read more

Material Availability This science project requires a kit available from the Science Buddies store. See the Materials and Equipment list for details. Estimated project time includes shipping.
Cost Average ($40 - $80)
Safety Never launch projectiles at people or animals. Be careful not to get your fingers caught in the moving parts of the catapult.
Science Fair Project Idea
thumbnail Have you considered where the gasoline that your parents put in your car comes from and how long that source will last? The fuel that most vehicles use, gasoline, is a petroleum product. Petroleum is a fossil fuel and is a nonrenewable form of energy, meaning we use it faster than it is able to be reproduced. Burning fossil fuels also produces pollutants that might hurt our environment. Using a kind of fuel from a renewable source would help save Earth's natural resources and cut down on… Read more
