Aerodynamics & Hydrodynamics Project Ideas (44 results)

You've seen for yourself, or in videos, planes flying, rockets hurdling towards space, boats racing through the water and submarines exploring the depths of the ocean. Have you ever stopped and thought about the aerodynamics and hydrodynamics involved in their operation? There is a lot of interesting science that goes into how they work! Check out these science and engineering projects to explore movement through air and water.

Science Fair Project Idea
Flying kites is an excellent way to learn about aerodynamic forces. In this science fair project, you will build and test a variety of kite designs to see which flies best in low wind speeds. You will use an inexpensive anemometer to accurately measure the wind speed. Since you will be choosing which kites to build and test, the experimental procedure provides a general outline for the experiments, but there is a lot of opportunity for you to be creative with your kite designs. This is a DIY… Read more

Time Required Average (6-10 days)
Prerequisites This is a "do-it-yourself" science fair project, because it's up to you to choose and build the different kinds of kites you wish to test. You will also design the experimental setup using a fan, which will require some creative problem-solving on your part.
Material Availability A couple of specialty items are needed. See the Materials and Equipment list for details.
Cost Average ($50 - $100)
Safety No issues

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

Alternative energy sources are a big deal these days. One such source is the wind. Find out how a wind turbine can use the power of the wind to generate energy in this science fair engineering project. You'll design various blades to find out which produces the most energy, and put the wind to work for you! Read more

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

Have you ever ridden on a carousel, or a merry-go-round, at an amusement park? On a carousel, you usually get to take a seat on a wooden horse or other animal that spins around and around as the carousel is turned on and powered by electricity. Another smaller type of carousel that people can have in their homes is a candle carousel, which is powered by heat from candles. In this science project, you will get to make your own candle carousel and investigate how the spinning speed of the… Read more

The Wright brothers used kites extensively to test their design ideas in the years leading up to their first successful airplane flight. With this science project, you'll learn about kite aerodynamics, and then come up with your own hypothesis about building or flying a kite. You can test your hypothesis two ways: with an online kite simulation program from NASA, and outdoors with the real thing! A great feature of this science project is that it has many possible variations, so you can decide… Read more

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

If you have an air hockey table, you know that the puck floats on a thin cushion of air when the table is turned on. With little friction, the puck can travel very fast. How much lift force is created by the air? Add small amounts of weight to the puck and see when it no longer floats to measure the lift force. How many air holes (on average) support the puck? How much force is generated by each air hole? Will a puck with a larger surface area, supported by more air holes (on average),… Read more
