Science Fair Project Idea
thumbnail Watching professional racing-car drivers compete can be thrilling. The high speeds that racing cars can reach — up to 200 miles per hour (mph) and more! — put some unique demands on the vehicles. For example, to withstand high temperatures, the tires must be inflated with nitrogen gas, instead of air as with normal car tires. This enables the drivers to have better control over steering their cars as they race around the track. In this sports science project, you will inflate… Read more

Science Fair Project Idea
As you move up or down in altitude or elevation, the temperature and pressure will change. This is particularly striking if you live near a mountain range. During the summer, at low altitudes you may have temperatures in the 80's or 90's and still be able to see snow on mountain peaks at high altitude. You can test the effect of altitude by comparing temperature data from weather stations at high and low altitudes. You can test the effect of elevation by making your own weather balloon and… Read more

thumbnail Race car drivers need every advantage they can get to give them the competitive edge in a race. In addition to human factors, like driving skill and reaction time, their cars must overcome physical forces, like air resistance, to maintain their high speeds. While this science project will not have you driving around a race track at 200 miles per hour, you will get to test how increased air resistance affects a real car's fuel economy. You will do this by measuring and comparing the gas mileage… Read more

Time Required Long (2-4 weeks)
Prerequisites None
Material Availability This science project requires an adult volunteer with a driver's license and who is allowed to drive a car. A car that already has a detachable roof rack is recommended, but a detachable roof rack may be purchased to do this science project. See the Materials and Equipment list for details.
Cost Average ($50 - $100)
Safety Never try to record data or distract the driver while you are in a moving vehicle. Always collect your data when the car is parked at home.
Science Fair Project Idea
thumbnail Have you ever had several different design ideas for a project and not known which one to try first? Engineers use computer models of real-world objects called simulations to help them make decisions before they start building prototypes. This helps them save time and money, so they do not have to physically build and test each design they come up with. In this project, you will use a free physics simulation program called VoxCAD. VoxCAD has been used for research at NASA, MIT, and other… Read more

thumbnail Suspension bridges, with their tall towers, long spans, and gracefully curving cables, are beautiful examples of the work of civil engineers. How do the cables and towers carry the load that is on the bridge? Can a suspension bridge carry a greater load than a simple beam bridge? This science project shows you how to find out. Read more

Walk into any music store and you'll find a dizzying array of string choices for your classical guitar, including rectified nylon, clear nylon, carbon fluoride, bronze wound, phosphor bronze wound, silver-plated copper wire, Polytetra-flouro-ethylene (PTFE), each in a range of tensions from low to high. There is no single best brand or best material. All have their advantages and disadvantages. A set of strings that sounds "sparkling" on one guitar might sound dull on another, primarily because… Read more

Science Fair Project Idea
Solar power is hot these days. Gleaming, black solar panels soak up rays on more and more rooftops of homes and businesses providing a clean, alternative source of heat and electricity. You might guess that different times of the day yield different levels of solar power. But just how much does the sun's position in the sky affect the power that solar cells and panels can generate? That's the question this project is all about. Read more

Science Fair Project Idea
thumbnail You probably know that turning off the lights and the water, and not wasting paper are all ways to help the environment and conserve our resources. Did you know that another way is to use fuel cells? A fuel cell is a device that converts the energy in chemicals to electricity and it creates no pollution. The starting chemical does not have to be something complex — in fact you it can even be water! In this science fair project try your own hand at converting water to electricity with the… Read more

Safety To do this science fair project, you will need to electrolyze water into hydrogen and oxygen. Hydrogen is flammable, so keep the fuel cell and hydrogen storage tank away from sparks.
Science Fair Project Idea
thumbnail In our , you were challenged to use the VoxCAD software to design the fastest possible robot using different materials. However, we did not ask you to think about one big thing — efficiency. It is great to design a robot that is very fast, but what if it also consumes a lot of energy? Engineers must consider this when designing robots in the real world — robots that use more energy to move will drain their batteries faster, which can be a problem. This is similar to the concept of… Read more
