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

Can Plants Stop Soil Erosion?

Science Fair Project Idea

Scientific Method

Soil erosion can cost the world billions of dollars every year by washing pollutants into our streams and rivers and by causing the loss of farmland. What can you do about this problem? Help save the world (and some money!) with nothing more than a few plants! Read more

Can the Color of Your House Reduce Your Energy Footprint?

Science Fair Project Idea

Scientific Method

Did you know that the color of your house could save money? Do this experiment to see which colors regulate temperature best in different environments. Then convince your parents to paint the house and save some money on their energy bill. Maybe they will be so happy they will also increase your allowance! Read more

Can Video Games Be a Form of Exercise?

Science Fair Project Idea

Scientific Method

Have you ever played a video game that made you break a sweat? Or pant a little bit? The majority of video games are sedentary, meaning done in one position, but there is an increasing trend toward video games where the players are physically active. Do you think these video games can be considered exercise? This science fair project will help you find out! Read more

Can Water Float on Water?

Science Fair Project Idea

Scientific Method

Of course it can, you say: ice is water and ice floats! And you're right. But we're talking about water in the liquid phase (the title reads better without getting overly specific). So how about it? Can liquid water float on water? Check out this project to find out. Read more

Can Water Plants Be Used to Determine Water Quality?

Science Fair Project Idea

Scientific Method

Some plants grow only in water-logged environments. These plants are usually native to wetlands and are important for the sustainability of aquatic ecosystems. Wetland ecosystems are very fragile and susceptible to the toxic dumping of sewage and fertilizer run-off from neighboring farm land. One very common aquatic plant called duckweed inhabits many wetland marshes. Duckweed grows by asexual reproduction and floats at the surface of the water with tiny roots extending into the water below.… Read more

Can You Change the Rate of a Chemical Reaction by Changing the Particle Size of the Reactants?

Science Fair Project Idea

Scientific Method

The ingredients in Alka-Seltzer® tablets undergo a chemical reaction that produces carbon dioxide gas as soon as the tablets hit water. Do you think you can cause the tablets to produce gas faster by breaking them into smaller pieces before dropping them in water? Find out for yourself with this project. Read more

Can You Hear Sounds in Outer Space?

Science Fair Project Idea

Scientific Method

Have you ever wondered what sounds you can hear in space? The answer is simple: none! In outer space there is utter silence. There are no sounds of traffic jams or thunderstorms or crashing waves. No buzzing bees or babies crying. Just silence. In this experiment, you will discover why empty space is void of sound and prove it with the help of the microphone in your phone and a sensor app. Read more

Can You Make a Happy Song Sad?

Science Fair Project Idea

Scientific Method

Are there some songs that always make you feel sad when you hear them? How about "Scarborough Fair," George Gershwin's "Summertime," or the Beatles' "Eleanor Rigby"? All of these songs are in a minor key. Minor and major scales both use the same number of notes and include the same number of semitones (also called half tones), but in a different pattern. Some musicologists (people who study music) maintain that minor-key songs are more likely to be perceived as sad, while major-key songs are… Read more

Can You Predict a Bird's Lifestyle Based on Its Feet?

Science Fair Project Idea

Scientific Method

Animals survive in all sorts of extreme environments, whether it is a polar bear out and about when it is -40°F, a desert iguana trying to find food as the temperature rises to 110°F, or a deep sea anglerfish living 3281 feet down into the sea. How do they do it? The answer is adaptations! Their bodies have special features that allow them to live in those environments. You might not be able to dive down 3281 feet to observe the deep sea anglerfish, but in this science fair project you… Read more
