Oil and Vinegar Do Mix…When You Have an Emulsifier

Science Fair Project Idea

Scientific Method

In this cooking and food science fair project, you will explore the role of proteins as emulsifying agents. Emulsifying agents are substances that are soluble in both fat and water and enable fat to be uniformly dispersed in water as an emulsion. Foods that consist of such emulsions include butter, margarine, salad dressings, mayonnaise, and ice cream. Emulsifying agents are also used in baking to aid the smooth incorporation of fat into the dough and to keep the baked goods tender. Natural… Read more

Scientific Method

Sauerkraut, pickled fish, pickled vegetables, kimchi, corned beef, processed cheeses, smoked lunch meats. Do you like these high-salt foods? What about your grandparents, do they? Do your grandparents seem to like most foods to be a bit saltier than you do? Try this science fair project if you want to find out more about the incredible, edible rock known as salt, and why people vary in how much of it they like to eat. Read more

Ow, My Tummy Hurts! The Biology and Chemistry of Gas Relief

Science Fair Project Idea

Scientific Method

Have you ever wondered why bubbles form when you mix soap and water? Is it possible to mix soap and water without making bubbles? Medical doctors actually study similar questions when they treat patients who have too much gas trapped in their digestive system, which can cause pain and bloating and also signal a serious medical problem. Some drugs, including one called simethicone, can help relieve extra gas in the digestive system. In this science project you will find out how simethicone… Read more

Parachutes: Does Size Matter?

Science Fair Project Idea

Scientific Method

How does a parachute work? Do bigger parachutes work better than smaller parachutes? Find out in this science project if the size of the parachute matters. Read more

Pedalism and Movement

Science Fair Project Idea

Scientific Method

Humans are bipedal, which means we walk using two legs. This gave humans an adaptive advantage during the evolution of humankind. Being bipedal gave humans additional speed, balance and flexibility used for walking, hunting or traveling long distances. However, we may have lost the ability to climb or swing in trees like other primates. How much faster can you go when you are bipedal? Have a race with your friends using two legs, and then four legs (use your arms as your 3rd and 4th legs).… Read more

Pedigree Analysis: A Family Tree of Traits

Science Fair Project Idea

Scientific Method

Some characteristics, like the shape of your hairline or whether your earlobes are attached or detached, are inherited from your parents. In this science project you will see how writing these characteristics onto a family tree can help you determine how they are inherited Read more

Perfect Plating: Which Food Presentation Technique is Best?

Science Fair Project Idea

Scientific Method

Did you know that people eat with their eyes as well as with their mouths? Food presentation—also called plating techniques or garnishing—makes food appear more appetizing. Checking out how the food looks is the cook's last task and the diner's first. Food that is well-presented is beautiful, colorful, and captivating. Not only does it make the diner really want to eat, but good presentation also allows the diner to identify the food ingredients, their quality, and the technique… Read more

Pet Poll: A Taste Test for Fluffy & Fido

Science Fair Project Idea

Scientific Method

Has your dog ever barked, seemingly for no reason at all? Or has your cat ever stopped and carefully smelled a spot that looked perfectly clean to you? Pets, like people, have senses that they use to learn about and to react to their world, but their senses can be stronger or weaker than people's. In this mammalian biology science fair project, you'll study your pet's sense of taste by conducting taste tests and watching how your pet acts to determine his or her favorite type, flavor, or brand… Read more
