Water from Air: Experimenting with Dew Traps
Science Fair Project Idea
Scientific Method
Most of us live in areas where sources of water exist nearby as oceans, rivers, lakes, ponds, streams, reservoirs, wells, or even underground streams. But in some places, like the desert, water is hard to find and a precious resource. In this environmental engineering science project, you will investigate one way that people living in arid regions can collect water inexpensively: dew traps. Read more
How Fatigue Changes Balance
Science Fair Project Idea
Scientific Method
Balance is one of the most important parts of how our bodies work. Even standing still requires the brain, muscles, eyes, and inner ears to coordinate perfectly. But what happens when you get tired—even just a little bit—from something like dancing, running, jumping in place, or doing step-ups for a short period of time? Many scientific studies show that fatigue—both mental and physical—can make balance worse. For example, after short bursts of physical activity, people… Read more
Effect of Friction on Objects in Motion
Science Fair Project Idea
Scientific Method
The funny thing about friction is that you couldn't get anywhere without it, yet it still acts to slow you down as you're getting there. Here is an easy project to measure the effects of friction. Read more
Air Particles and Air Quality
Science Fair Project Idea
Scientific Method
What does the phrase, "Like a breath of fresh air," mean to you? This common phrase can have different meanings: calming, relaxing, invigorating, energizing or CLEAN! After all, you never hear anyone say, "Like a breath of dirty air," do you? Find out how clean the air is in this simple experiment. Read more
From Dull to Dazzling: Using Pennies to Test How pH Affects Copper Corrosion
Science Fair Project Idea
Scientific Method
Pennies are bright and shiny when they are new, but become quite dull with time. What causes such a drastic change? Oxygen in the air combines with the copper in the penny to form copper oxide, which makes the penny look dull and dingy. You can make the pennies look like new again by soaking them in water that is corrosive enough to strip off the copper oxide layer. It turns out, however, that the same process that makes the pennies shiny has bad consequences when it comes to copper pipes: it… Read more
Conduct Galileo's Famous Falling Objects Experiment
Science Fair Project Idea
Scientific Method
Standing on a balcony near the top of the Tower of Pisa in Italy, a young scientist dropped two balls into the crowd below. The scientist, young Galileo, was not trying to knock his fellow professors on the head, but was trying to prove his theory that all objects fall to earth at the same rate, regardless of their mass. Was Galileo's theory correct? In this science project, you will get to test it out for yourself! Look out below! Read more
The Viscosity of Motor Oil
Science Fair Project Idea
Scientific Method
The insides of a car engine get very hot when the engine is running. Motor oil lubricates the moving parts, to keep the engine operating smoothly. What happens to motor oil as the engine temperature goes up? Read more
Which Stars Can You Use for Navigation in Different Parts of the World?
Science Fair Project Idea
Scientific Method
Do you ever wonder how pirates sailed the seven seas? The two most important things a pirate could have (besides a parrot and big hat) were a compass and an accurate watch. Ancient navigators didn't know about compasses, so how did they know where they were going? Could they have used the stars to know which way to go? Read more
Investigate the Greenhouse Effect
Science Fair Project Idea
Scientific Method
Has the temperature in your house felt hotter or colder recently? This could be due to the greenhouse effect. The greenhouse effect states that gases in the atmosphere, such as CO2, might increase the surface temperature of Earth. In this science fair project, you will build a small model of Earth and use it to see how the temperature varies, compared to outside of the model. If you select this science fair project, you will be a part of the effort that is working to figure out what role… Read more
Can Nanotechnology Help Clean Up Ocean Oil Spills? Try It Yourself with Ferrofluid
Science Fair Project Idea
Scientific Method
The enormous task of cleaning up oil spills in oceans and seas has burdened industry, government, and environmentalists for decades. The cleanup is almost always difficult. It involves great amounts of time, resources, and money to remove the oil from the water, and the cleanup is often only partially successful. Today, however, scientists are coming to the rescue, developing a new technique that combines nanotechnology and magnetism. In this science project, you will test the proposed… Read more
