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.

Mixing Your Own Marshmallows: Finding the Right Ratio of Sugar to Corn Syrup

Science Fair Project Idea

Scientific Method

Whether you are sitting around a campfire, or drinking hot chocolate after a day in the snow, nothing says fun quite like a marshmallow! Even its name is soft and spongy! In this cooking and food science fair project, you will make your own marshmallows several different ways, and discover the three special ingredients that give marshmallows their unique texture. You will also find out why they melt so quickly. Explore the science of these sticky, spongy sweets! Read more

Dog Toys: What Makes One a Favorite or a Flop to Fido?

Science Fair Project Idea

Scientific Method

Got a pampered pooch in your household? Then you know how much most dogs love their toys. And not just any toy. It has to be that particular beat up ball, gnawed frisbee, or ratty not-so-plush-anymore bunny with only one eye and partial ear remaining. Seems that dogs, like people, have definite preferences for their play things. This fun project investigates what makes a toy interesting to a dog. In these experiments, you and your dog can have some fun while you learn about canine behavior… Read more

Blowing Bottle Tops: Making Music with Bottles

Science Fair Project Idea

Scientific Method

Have you ever blown across a bottle's top and made a pleasant, resonant sound? If so, have you wondered how that note is made exactly? A bottle is actually what is called an air cavity, also known as a Helmholtz resonator. Ocarinas are examples of musical instruments of this type. In this science project, you will use bottles to investigate how the volume of air in the cavity affects the pitch of the note that it makes. All you need are some bottles, water, a ruler, and a chromatic tuner. 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

Do Submarines Need Fins?

Science Fair Project Idea

Scientific Method

What keeps a submarine from spinning out of control? In this science project, you can investigate how submarines use stabilizing fins to move forward. You might even figure out the secrets to maneuvering a submarine! Read more

The Cold Wash Challenge: Testing How Well Enzymes Work in Laundry Detergents

Science Fair Project Idea

Scientific Method

What do you think are some of the most common stains on clothes? If you thought of grass, grease, ketchup, blood, or toothpaste stains, you are correct. Everyday activities like eating, playing outside, or doing sports can result in a lot of dirty laundry. Luckily, we have laundry detergents that can get our clothes clean again! Some of these detergents contain enzymes that are intended to boost cleaning power. In this science project, you will investigate how effective biological and… Read more

Effects of Exercise: Changes in Carbon Dioxide Output

Science Fair Project Idea

Scientific Method

You might know that your body needs oxygen to keep going, and that you breathe out carbon dioxide as waste. What happens when you exercise? You have probably noticed that you breathe faster, and your heart beats faster. What triggers your body to respond in this way? How does it "rev up" to keep your muscles going? In this project, you will get a peek into the fascinating science of exercise physiology and find out—with the help of a color changing reaction. Read more

Big Pieces or Small Pieces: Which React Faster?

Science Fair Project Idea

Scientific Method

Some chemical reactions occur explosively fast, others may occur almost imperceptibly s-l-o-w-l-y. This project explores what effect the particle size of the reactants has on the speed of a chemical reaction: production of carbon dioxide gas by an Alka-Seltzer® tablet. Read more

Can Biodegradable Materials Replace Plastic as Protective Food Packaging?

Science Fair Project Idea

Scientific Method

Many foods, such as fresh fruits, vegetables, or eggs, are packaged in plastic to protect them from damage during handling and transport. But is plastic the best choice? What if a more sustainable and biodegradable material could replace it? Researchers have begun exploring hydrogels—squishy materials that can hold a lot of water—as alternative packaging materials. In this science project, you will make your own hydrogels from gelatin and cornstarch and investigate what ratio of… Read more
