Eighth Grade, Aerodynamics & Hydrodynamics Science Projects (28 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!

Make the Wind Work for You!
Science Fair Project Idea
Scientific Method
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
Take a Candle Carousel for a Spin
Science Fair Project Idea
Scientific Method
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
Studying Bernoulli's Principle
Science Fair Project Idea
Scientific Method
Did you know that you can actually make objects come together by blowing air between them? Find out how wind changes air pressure to bring to objects together in this easy and fun science fair project! Read more
The 'Ultimate' Science Fair Project: Frisbee Aerodynamics
Science Fair Project Idea
Scientific Method
Are you good at tossing a Frisbee®? It is great when you throw a perfect, arcing curve, right on target! If you can do that, you have already trained your arm on the aerodynamics of Frisbee flight. Why not treat your brain to some Frisbee science with this project? Read more
Why Winglets?
Science Fair Project Idea
Scientific Method
Have you ever noticed how some jet planes have small, vertical projections as the tips of the wings? They're called winglets. What are they there for? Read more
The Wright Stuff: Using Kites to Study Aerodynamics
Science Fair Project Idea
Scientific Method
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
Riding on Air—Build a Real Hovercraft
Science Fair Project Idea
Scientific Method
Looking for an exciting new mode of transportation? In this science fair project, you will build a working hovercraft that will glide over surfaces on a cushion of air. And it's simpler to build than you might think! 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
Efficient Propeller Design
Science Fair Project Idea
Scientific Method
How does a helicopter generate enough lift to fly? How does a speedboat get moving fast enough to pull someone on water skis? Here's a project on designing propellers to do the job. Read more
Helicopter Liftoff: How Does the Speed of the Rotor Affect the Amount of Lift?
Science Fair Project Idea
Scientific Method
Helicopters are fascinating to watch. The spinning rotor blades on top of the helicopter generate lift, allowing it to take off vertically. They can land vertically, too, allowing them to set down in small spaces, such as hospital helipads or on a ship at sea. In this aerodynamics science fair project, you will fly a remote-controlled helicopter and measure how the rate of the rotor's rotation changes as the helicopter hovers and flies up or down.
