It's time to set sail! Even if you live nowhere near a lake or ocean, you will get to do some sailing in this science activity as you build your own toy sailboat. But first, you have to make sure your boat doesn't capsize! Are you up for the challenge? Read more
Do Submarines Need Fins?
Science Fair Project Idea
Scientific Method
What keeps a submarine from spinning out of control? In this science project, you can investigate how submarines use stabilizing fins to move forward. You might even figure out the secrets to maneuvering a submarine! 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

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
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
