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

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.

Making your own bubble solution is fun, but sometimes the bubbles don't seem to work as well as the solutions you buy in the store. In this experiment you can test if adding corn syrup or glycerin to your bubble solution will make it just as good as the stuff you can buy. This experiment will have you blowing bubbles! Read more

Have you ever wondered why a water strider can walk on water? Or how detergent can clean your dishes? If you observe carefully, you can find dozens of similarly interesting phenomena that are all linked to the surface tension of water. In this science project, you will investigate the properties of water surface tension. Read more

Can you lift a car? No? You say you are not strong enough? True, our bodies are not built to lift heavy loads like cars. Fortunately, our brains are smart enough to harness the power of fluids, like water and oil, to create hydraulic lifts. By pushing a button on a hydraulic lift, a mechanic can easily raise a car with one finger. Lifts can also be used to raise lots of other heavy loads - even such massive things as steel girders to construct a skyscraper! In this mechanical engineering… Read more
