How Does the Number of Parachutes Affect Terminal Velocity?
Science Fair Project Idea
Scientific Method
Have you ever wondered how astronauts land safely back on Earth? Many spaceships use a small crew capsule with multiple large parachutes to bring the astronauts down to a gentle landing either on the ground or in the ocean. What happens if one or more of the parachutes fails to deploy? Can the astronauts still land safely? Find out as you explore the physics of falling with parachutes in this project.  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
Modifying a Car for Better Aerodynamics
Science Fair Project Idea
Scientific Method
Have you ever seen those cool wind tunnel pictures of cars with streams of smoke blowing over them? You do not need access to a wind tunnel to do a car aerodynamics science project! In this project you will use cheap, readily available materials—tape and yarn—to visualize airflow over a car. You will examine how you can affect the airflow over the car by making changes, like adding or removing accessories or making body modifications out of cardboard and duct tape. Maybe you can… 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
Rocking the Boat
Science Fair Project Idea
Scientific Method
When a ship rocks back and forth, it can make people seasick. Even worse, it can make it dangerous for jets to land on aircraft carriers. For these reasons and many others, it's important for engineers to design bilge keels (or fins) to keep boats from rolling back and forth. Become an engineer for a day and discover the best way to keep from rocking the boat in this engineering science fair project! 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
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
Aerodynamics of Air Hockey
Science Fair Project Idea
Scientific Method
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
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
Study Bottle Rocket Performance with Electronic Sensors
Science Fair Project Idea
Scientific Method
Rocket design and operation is a fascinating field and analyzing the flight path provides insight into the rocket's performance. In this project, you will take measurements of the flight path to evaluate how a change in the rocket design or launch procedure impacts the rocket's performance. Initially, while the bottle rocket expels water (or the rocket expels exhaust), the rocket gets a boost. This push is referred to as thrust and projects the rocket forward. Earth's gravity pulls the rocket… Read more
