Alternative energy sources are a big deal these days. One such source is the wind. Find out how a wind turbine can use the power of the wind to generate energy in this science fair engineering project. You'll design various blades to find out which produces the most energy, and put the wind to work for you!

Have you ever ridden on a carousel, or a merry-go-round, at an amusement park? On a carousel, you usually get to take a seat on a wooden horse or other animal that spins around and around as the carousel is turned on and powered by electricity. Another smaller type of carousel that people can have in their homes is a candle carousel, which is powered by heat from candles. In this science project, you will get to make your own candle carousel and investigate how the spinning speed of the…

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…

Have you ever wondered how a ship made of steel can float? Or better yet, how can a steel ship carry a heavy load without sinking? In this science project you will make little "boats" out of aluminum foil to investigate how their size and shape affects much weight they can carry and how this relates to the density of water.

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!
