Others Like “Build a Raft Powered by Surface Tension”

Project Idea
Have you ever wondered what makes water 'bead' up on a freshly waxed car? In this project you'll investigate the chemistry of surface tension by measuring how many drops of water a penny can hold. What happens if you add salt or detergent to the water? Read more

thumbnail 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

Project Idea
thumbnail 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

thumbnail Where do you get your best ideas? At school with your friends? When you're 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

Project Idea
thumbnail You may have heard the expression, "You can't get blood from a stone." But what about oil? Can you get petroleum oil from a stone? In this geology science fair project, you'll find out what kinds of stones make the best storage rocks for oil. You'll see which ones can soak up oil like a sponge, and which ones cannot soak up oil or let it pass through, but can act as a “cap” to contain the oil in secret underground traps. Can a hard rock really act like a soft sponge…maybe SpongeBob SquarePants… Read more

Project Idea
thumbnail Watching professional racing-car drivers compete can be thrilling. The high speeds that racing cars can reach — up to 200 miles per hour (mph) and more! — put some unique demands on the vehicles. For example, to withstand high temperatures, the tires must be inflated with nitrogen gas, instead of air as with normal car tires. This enables the drivers to have better control over steering their cars as they race around the track. In this sports science project, you will inflate… Read more

Project Idea
thumbnail Close your eyes for a moment and think about your favorite cake, pasta, and crusty bread. OK, you can open your eyes now, and please don't drool on your computer! What was the cake you pictured like? Was it light and fluffy? Did you imagine pasta with a silky, smooth texture? Was the bread you pictured wonderfully chewy? Did it give your jaws a workout? In this science fair project, you'll explore an amazing substance in these foods, called gluten, and discover why these foods, all made from… Read more

Project Idea
thumbnail Have you or one of your pets ever been sprayed by a skunk? Hopefully not, but if you have, you probably know that the smell can be very unpleasant and hard to get rid of. There are many "folk remedies" for getting rid of skunk scent, but if you ever do get sprayed by a skunk, how will you know which one to try? In this science project, you will test the ability of various mixtures to remove the bad scent from rags that have been contaminated with bottled skunk scent, and determine which one… Read more
