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 '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

What's The Best Way to Land a Model Rocket?

Science Fair Project Idea

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

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

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

Model Rocket Aerodynamics: Stability

Science Fair Project Idea

Scientific Method

What keeps a model rocket on course? How can you make sure a model rocket design is stable before you launch it? Find out in this project as you learn about center of mass, center of pressure, and their effect on a rocket's stability. Read more

Rocket Science: How High Can You Send a Payload?

Science Fair Project Idea

Scientific Method

Rockets are definitively an engineering challenge. These amazing gravity-defying machines have lifted test material, people, and even animals into space. Feel like building one yourself? In this science project, you will transform a water bottle into an aerodynamic bottle rocket with two compartments, one for the fuel and one for a payload. You will then test how well it performs when lifting mass vertically up into the air. Ready, set, soar! Read more

Build a Two-Stage Balloon Rocket

STEM Activity

67 reviews

If you have ever watched a rocket launch on TV, you might have noticed that rockets have multiple stages. Some parts of the rocket fall off and burn up in the atmosphere whereas the rest of the rocket keeps going. Why does this happen? Try this activity to find out and build your own two-stage rocket using balloons! Read more

Build an Archimedes Screw

STEM Activity

82 reviews

The Archimedes screw is an ancient device used to lift water from one location to another. They are so useful that they are still in widespread use today! After a quick trip to the hardware store, you can build your own Archimedes screw in this fun activity. Read more

Flying Helicopters on Mars

STEM Activity

70 reviews

During the Mars 2020 mission, NASA plans to explore the surface of Mars using a rover in combination with a lightweight helicopter. To be able to fly on Mars, this helicopter must be super light and have very efficient blades. If not, it will never generate enough lift to get off the ground. In this activity, you will make your own paper helicopter and test different blade designs. Will your findings be reflected in NASA's design? Try it out and see for yourself! Read more
