Do you ever wonder what mathematicians study, and why? Most of what they do is complex and inaccessible to laymen, but fractal art might give us a glimpse. While mathematicians study fractals formally, they are used in many branches of science and technology, and we, as laymen, are struck by their beauty. Are you eager to create one? In this activity, you will get to take out some finger paint to make artwork and discover how common fractals are. Read more

Milk Does Your Body and a Boat Good—Design Your Own Milk Carton Boat

Science Fair Project Idea

Scientific Method

Who'd have thought that drinking milk can lead to a pretty cool boat? Boat design is an important and active area of engineering. In this science fair project, you will design and build different kinds of model boats out of milk cartons. Examples of the types of designs you might test include a raft, a catamaran, and a V-shaped hull. Once the model boats are built, you will test key features, such as stability, maneuverability, and their ability to glide. Read more

Minding your Mummies: The Science of Mummification

Science Fair Project Idea

Scientific Method

Have you ever seen or heard of the movies The Mummy or The Mummy Returns? Mummies have always played a part in nightmares for Western cultures, but in ancient Egypt, mummification was a serious religious ritual. They believed that preserving human remains was necessary so that the previous owner could enjoy the fruits of the afterlife. In this science fair project, you will learn about the rituals and science of mummification by mummifying a hot dog. Read more

Minerals

Science Fair Project Idea

Scientific Method

Minerals are sometimes precious, like diamonds. But most minerals are very common, like sodium, which is found in salt. How are minerals found and identified? How are our mineral resources distributed? Visit the USGS Mineral Resource Program to find mineral resources in your state. How are satellite images used to identify potential mineral sources? You can also find out how minerals are identified using spectroscopy. How are potentially harmful minerals, like mercury, dealt with? Visit the… Read more

Minimizing Bacteria in the Thawing and Cooking of Meat

Science Fair Project Idea

Scientific Method

How does your family thaw and cook meat? Have you ever wondered if it is the safest way? In this practical science project, you can find out and shed light on safe practices in the kitchen by investigating how many viable bacteria are present in samples of meat that have been thawed or cooked using different methods.

Mixing Mystery: Why Does Tumbling Sometimes Separate Mixtures?

Science Fair Project Idea

Scientific Method

What do sand and cereal have in common? They are both granular materials, which means they are made up of solid particles, but they can actually flow like liquid. When two granular materials with very different-sized particles are mixed, you can actually separate each type by putting them in a rotating device called a tumbler. In this science project, you will examine how common household granular materials behave when mixed together in a moving container Read more

Has an adult ever caught you munching on candy and asked, "How much candy have you eaten?" Instead of saying, "I don't know," and possibly receiving a scolding, wouldn't you rather respond, "I ate precisely 10.7 cubic centimeters of candy"? In this activity, you will investigate which mathematical formula is most accurate for estimating the volume of an M&M. Figure this out and the next time you are discovered while snacking on sweets, you might make a… Read more

Model How Environment and Genetics Change the Chances of Getting Cancer

Science Fair Project Idea

Scientific Method

What is cancer? How does it develop? Doctors and scientists have asked these questions for hundreds of years to understand cancer and find treatments. In this science project, you can investigate these questions too by building a simple model and exploring how environmental and genetic changes affect the development of cancer. Read more

Have you ever wondered why you need to get a flu shot regularly? The vaccine protects you from getting sick with the flu, which is an infectious disease. Such diseases, like the flu or COVID-19, can easily spread through a population and cause a pandemic by making many people sick. Measures such as social distancing can reduce the risk of catching the disease, but real protection only comes from gaining immunity against the disease. This is the reason for vaccinations—to make someone… Read more

Modeling the Chances of Getting an Autoimmune Disease

Science Fair Project Idea

Scientific Method

Do you know someone who has an autoimmune disease? Autoimmune diseases are fairly common, affecting more than 23.5 million people in the United States, which is about 1 in 13 people! You may have heard of some of them, such as diabetes (type 1), rheumatoid arthritis, and celiac disease. Many autoimmune diseases are poorly understood, but they all have one thing in common: they happen because a person's immune system (which normally fights off germs to keep the person healthy) attacks the… Read more
