Butterfly Wings: Using Nature to Learn About Flight

Science Fair Project Idea

Scientific Method

Have you ever seen butterflies fluttering around outside, gliding through the air and landing on flowers? While they are delicate and fragile, butterflies are actually excellent flyers. They are so good, in fact, that scientists at Harvard University studied butterfly wing shapes as an inspiration for building a miniature flying robot. In this science project, you will do your own version of the Harvard scientists' experiment to measure the flight performance of butterfly wings. Read more

Make Your Own Hot Air Balloon

Science Fair Project Idea

Scientific Method

Have you ever looked up into the sky and seen not a bird, not a plane, but a hot-air balloon? They are definitely amazing and fun to watch! Do you think they are all the same size? Does size affect how long the hot-air balloon can fly? In this science fair project, you will launch hot-air balloons, powered by a toaster, and see how the size of the balloon affects its flight.

Archimedes Squeeze: At What Diameter Does an Aluminum Boat Sink?

Science Fair Project Idea

Scientific Method

Where do you get your best ideas? At school with your friends? When you are out for a bike ride? Over 2,200 years ago, a scientist named Archimedes got one of his best ideas when he sat down in his bath. Eureka! He went running through the streets without even bothering with his clothes. What was he so excited about? He had discovered that when objects, like his body, are placed in water, water is pushed out of the way. Have you noticed that, too? The weight of the water that is pushed out of… Read more

If you have wondered how rockets are propelled forward or if you enjoy the excitement of launching a rocket, this is an activity for you! You will learn how to make tiny rockets from aluminum foil and matchsticks, and how to ignite them safely. Soon, you will be launching one rocket after the other! Your challenge will be to find the most reliable launching mechanism. 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

What A Drag!

Science Fair Project Idea

Scientific Method

What makes some objects more streamlined than others? Find out which ordinary objects around your house are made to move smoothly through the water in this easy science fair project. Which objects will produce the most drag when pulled through the water? Read more
