Science Fair Project Idea
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
Science Fair Project Idea
Have you ever wondered why bubbles form when you mix soap and water? Is it possible to mix soap and water without making bubbles? Medical doctors actually study similar questions when they treat patients who have too much gas trapped in their digestive system, which can cause pain and bloating and also signal a serious medical problem. Some drugs, including one called simethicone, can help relieve extra gas in the digestive system. In this science project you will find out how simethicone… Read more

What are some of the ways we keep track of time? We have alarm clocks, wristwatches, and cell-phone clocks, to name a few. Just a few hundred years ago, our ancestors did not have any of these conveniences, yet they found ways to tell time. How? By using devices such as water clocks. In this science project, you will follow in the footsteps of early engineers and build a water clock that tracks time for three hours. Read more

Did you know that even though water is a liquid, it isn't always able to get into little cracks and crevices? So how do clothes go from caked with mud to clean? How can dishes go from greasy to glistening? With a few simple household items, you can find out! Read more
Science Fair Project Idea
In this project you'll make a liquid that will contradict your expectations. Hold it loosely in your hand and it will drip off your fingers, but grab it tightly and it will feel solid. Slap a bowl of it with a spoon, and instead of splattering, it solidifies. Do background research on colloids, and be sure you can explain the following terms: colloid, Newtonian fluid, non-Newtonian fluid, thixotropic. (For instructions on how to make it see the link listed under Exploratorium, 1998, in the… Read more

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

Do you dream about making deep, undersea voyages? Let this project take you 20,000 leagues under the sea! Investigate how submarines dive and surface by changing their buoyancy in this fun project. Read more
Science Fair Project Idea
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.

Science Fair Project Idea
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
Science Fair Project Idea
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
