Science Fair Project Idea
Scientific Method
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

Scientific Method
Naval fighter pilots seem to defy physics each time they fly their jets off of an aircraft carrier. Normal runways are thousands of feet long so that airplanes can develop enough lift to fly. But a runway on an aircraft is much shorter. How can naval pilots get their fighter jets into the air without falling off the carrier into the ocean? Well, because they get a boost from a catapult! Sounds unbelievable? It's not, and you can find out more about catapult-assisted takeoff in this aerodynamics… Read more

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

Scientific Method
What's the best way to land a model rocket? What makes the rocket hit the ground safely at a low speed? What prevents the rocket from drifting too far if it's windy? In this project, you will make your own rockets from paper towel tubes and drop them to test different recovery methods like parachutes and streamers. What method do you think will work the best?  Read more

Engineering Design Process
Do you like playing with radio-controlled (RC) toys like cars, planes, and boats? What if you could build and customize your own? In this engineering project, you will learn how to build your own RC boat using an Arduino and a plastic food storage container. Read more
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

Scientific Method
Have you ever seen a maple seed twirling as it falls through the air? In this project you will build something that behaves similarly called a whirlybird. Will your whirlybird be able to stay in the air as you add paper clips as weights? Try this project to find out! Read more

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

Scientific Method
Do you wish that you had duck feet? Aside from being a fun Dr. Seuss story, there is a lot you can learn about hydrodynamics by looking at the feet of birds. How are the feet of birds that swim unique? Find out in this experiment. Read more
Science Fair Project Idea
Scientific Method
Have you ever ridden on a hovercraft? It is like gliding on a cushion of air! In this science project, you will make your own mini hovercraft using a CD or DVD and a balloon and investigate how the amount of air in the balloon affects how long the hovercraft hovers. Read more
