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

Solving a 'Windy' Problem

Science Fair Project Idea

Scientific Method

The wind is a powerful force, enough to erode whole hillsides over time. Building structures in windy environments challenge civil engineers with special safety concerns. A wall in a windy area can either shield you from the cold or fall down on you. Learn a few tricks on how to design walls in windy places. 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

Cold Room? Heat It Up with A Homemade Solar Air Heater

Science Fair Project Idea

Scientific Method

What do humans need to survive? We need food, water, and warm shelter. We all need a warm place to live, particularly when it's chilly outside. How do many of us warm our houses or apartments? We depend on fossil fuels to supply gas and electricity to our heaters. But burning fossil fuels to create energy is harmful to the environment. What if there was a way to warm our homes without burning fossil fuels and it was free? In this science fair project, you will build a solar air heater and see… 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.

Can Exercise Really Make Our Brains Work Better?

Science Fair Project Idea

Scientific Method

"Use it or lose it!" Sure, we all know physical exercise is important to keeping our bodies fit. But how important is physical exercise to your brain? In other words, is there any connection between an active body and increased brain power? This is an easy project where you can test the effect of exercise on a critical brain function: memory.

Get Crafty — Create Your Own Durable Paper Doll

Science Fair Project Idea

Scientific Method

Through the ages, creative minds have made an amazing variety of paper toys, many of them delicate, beautiful, and inspiring. All too often, though, they do not withstand very well the wear and tear of play. This science project is your chance to fix that. You will make paper dolls with movable parts and study how the choice of materials influence the strength of the toy. Beginning with a strong design, you will finish by making a durable paper doll (or toy) with moving parts. Read more

Sorting Out Sedimentation

Science Fair Project Idea

Scientific Method

Sedimentary rock forms in layers that are deposited one after the other over long periods of time. Oftentimes, sedimentary rock contains fossils and other debris that are deposited within the layers. How do sediments form? How are sediments of different shapes, sizes, and types sorted during the process of sedimentation? Find out in this science fair project! Read more

Be Seen After Dark—What Clothes Keep You Safe?

Science Fair Project Idea

Scientific Method

Did you know that the most likely time to be struck and killed by a car in the United States is at dusk, dawn, or at night? In 2014, 3 out of every 4 pedestrian fatalities happened in these types of poor light conditions. Is there something you could do to decrease the chances you, your friends, and your family members are safer when walking or biking at night? Do you think the types of clothes that you wear could make a difference in how visible you are to drivers? Explore the science of… Read more

Can Beeswax Wraps Replace Plastic Wraps?

Science Fair Project Idea

Scientific Method

Do you ever use plastic wrap to cover a container? Did you know that it is made of plastic, which significantly contributes to the amount of waste in our landfills? There are many alternatives to plastic, and one popular product is beeswax wraps. Are beeswax wraps a suitable replacement for plastic wrap? Find out in this experiment! Read more
