M&M Geometry

Science Fair Project Idea

Scientific Method

Have your parents ever found you munching on candy and asked you, "How much candy did you eat?" Instead of saying, "I do not know?" and getting in trouble, maybe you would rather say, "I ate precisely 10.7 cubic centimeters of candy, Mom." Make your parents proud of their candy-eating genius child (you) with this simple science project. Read more

Have you ever cooked up homemade candy, maybe from chocolate or table sugar? Maple syrup is not only deliciously gooey and great on breakfast foods like pancakes and waffles—you can also turn it into maple candies with an amazing range of textures! It can be made into sticky maple taffy, or hard, molded maple sugar candy. In this science activity, you will investigate how the temperature of heated maple syrup affects what types of candies can be made from it. Read more

Measuring the Moon's Brightness

Science Fair Project Idea

Scientific Method

Sometimes a full moon can be so bright, you can walk around in the dark without a flashlight. How much brighter is a full moon than the other phases of the moon? How is the brightness of the moon measured? Read more

Memory Mnemonics

Science Fair Project Idea

Scientific Method

Have you ever had to remember a long list of planets or the state capitals? These kinds of lists are full of interesting facts, but they can be hard to remember, especially for tests. What could you do to remember the list better? In this human behavior science fair project, you will learn about a memory technique called mnemonics (pronounced nuh-MAH-nicks) and investigate whether using mnemonics can help you and your friends remember lists of words.

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

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

4-LS1-1. Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behavior, and reproduction.

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

Modeling Your Local Watershed and Nutrient Pollution

Science Fair Project Idea

Scientific Method

Have you ever been unable to swim in a body of water because it was polluted? Have you ever wondered where the water came from, or what contributed to its pollution? In this science project, you'll learn how water drains to common areas to create bodies of water and how the land surrounding a waterway can contribute to its health and pollution. Read more
