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

Mixing Light to Make Colors

Science Fair Project Idea

Scientific Method

You know how to make new colors by mixing paint or crayons. For example, you get green by mixing yellow and blue, or orange by mixing red and yellow. With paint, blue, yellow, and red are primary colors, which you can use to make other colors. Have you ever tried making colors with light? Are the primary colors the same ones you use for paint? Do this experiment and find out. Read more

Molecular Scissors

Science Fair Project Idea

Scientific Method

Ever used a pair of molecular scissors? Restriction enzymes are molecular scissors that cut DNA into pieces. Find out which enzymes will cut, and where by making a restriction map. Then you can figure out what will happen if you change the sequence of the DNA. Will the same enzymes still cut the new DNA sequence? Read more

Moving Water with the Archimedes Screw Pump

Science Fair Project Idea

Scientific Method

Amaze your friends and family by moving water with just a few turns of your wrist! Nope, it's not a magic trick. It's simply an Archimedes screw. In this science project, you will build a very simple pump, called an Archimedes screw, to transfer water from a low-lying location to a higher location. Read more

Newspaper Tower

Science Fair Project Idea

Scientific Method

Predict how tall you can build a tower using only two sheets of newspaper as building material. You can't use tape, glue, staples, or anything else, just two sheets of newspaper. You can tear, bend, cut, or fold the newspaper. Try it out and see how close you can come to your prediction. Can you beat your prediction? As you're building, you may come up with ideas to make a better tower. Try them out! (It's not like the materials are expensive!) Here are some variations you might want to… Read more

No Pain, Lots of Game

Science Fair Project Idea

Scientific Method

You might have heard the expression, "Take two aspirin, and call me in the morning." What if instead a doctor said, "Play two video games and call me in the morning"? Would you be shocked? Or think it was time for a new doctor? In this science fair project, you'll investigate whether video games, and other forms of mental distraction, have the power to relieve pain. Read more

Now You See It, Now You Don't: A Chromatic Adaptation Project

Science Fair Project Idea

Scientific Method

This project shows that our perceptions can change, even with the stimulus remains the same. A clear color difference in an image disappears after just 20 seconds of looking at another (special) image. Now you see it, now you don't! Read more

Now You See It, Now You Don't! Test Your Peripheral Vision

Science Fair Project Idea

Scientific Method

Peripheral vision is important in our everyday lives because it allows us to gather a visual sense of our surroundings—without it, we would see the world through "tunnel vision." The survival of our ancient ancestors depended on their ability to use peripheral vision to find prey and to avoid predators. Almost everything we do—from riding a bike, to dribbling a basketball, to reading a book—depends on peripheral vision. In this human biology science fair project, you will test… Read more
