Making It Shipshape: Hull Design and Hydrodynamics

Science Fair Project Idea

Scientific Method

Sailboats, tugboats, barges, ocean liners, submarines are all different boats with different shapes. How does the shape of a boat's hull affect how easily it moves through the water? This project shows you how you can investigate this question using a homemade water trough and model boat hulls. Read more

Are you good at tossing a Frisbee? Have you ever wondered how a Frisbee is able to fly through the air so well? If you can throw a perfect, arcing curve, right on target, you have already trained your arm on the aerodynamics of Frisbee flight! In this science activity, you will investigate how the angle at which you throw the Frisbee affects its flight's direction and distance. Next time you are out tossing a Frisbee, this little lesson in aerodynamics may help make your throws be even… Read more

The True Cost of a Bike Rack: Aerodynamics and Fuel Economy

Science Fair Project Idea

Scientific Method

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

What Makes a Good Aerodynamic Design? Test Your Ideas with High-Performance Paper Gliders

Science Fair Project Idea

Scientific Method

You have probably made plenty of regular paper airplanes simply by folding a piece of printer or notebook paper. Have you ever tried making a "high performance" paper glider? These gliders use a different construction technique that involves cutting multiple shapes out of thicker, stiffer paper and gluing them together (this process is called lamination). There are many resources online that can get you started with the art of making high performance paper gliders. See the references in the… Read more

Why Do Flying Rings Go So Much Further Than Frisbees?

Science Fair Project Idea

Scientific Method

If you've played catch with both Aerobie flying rings and Frisbees, you know that the rings fly much further than the Frisbees with the same throwing effort. Why is that? Investigate the aerodynamics of flying rings and flying disks and find out! Read more

Wind Turbine Efficiency

Science Fair Project Idea

Scientific Method

Try different wind turbine/propeller (chord length, pitch) designs by making models from balsa wood. Connect the spinning axle to a DC motor and measure the voltage produced across a resistor to measure power output. Use fan as wind source. (Judge, 2004) Read more

Investigating Fluid Viscosity

Science Fair Project Idea

Scientific Method

You can measure the viscosity of a fluid using a glass tube and a marble with slightly smaller diameter than the tube. Seal one end of the tube. Fill the tube with the fluid to be tested. Drop the marble into to the tube and measure the time it takes to fall a fixed distance. Repeat the measurement several times, and use the average value. How does viscosity change with the amount of sugar dissolved in water? How does viscosity change with temperature? Read more

How do quadcopters (drones with four propellers) steer? Find out in this fun project as you program an Arduino to steer a mini popsicle stick drone! See this page for a complete list of our mini drone projects. You may wish to do the projects in order. Read more

Showing the Airflow in a Wind Tunnel

Science Fair Project Idea

Scientific Method

A technique often used in wind tunnels is to introduce smoke in front of the airfoil that is being tested. The smoke comes from regularly-spaced point sources, and the wind flow in the tunnel spreads it out into parallel lines, called streamlines. The streamlines make it possible to visualize the airflow over the airfoil. When the lines continue smoothly over and past the airflow, they show that the flow remains laminar, and that the airfoil is creating very little drag. When the… Read more
