Finding Phyla

Science Fair Project Idea

Scientific Method

Have you ever wondered how many different types of animals live around your home, like in your backyard or a local park? Animals come in all shapes and sizes, each a small part of the amazing diversity of life. These differences can also help us to classify animals into different groups. One way people classify animals is by their phylum. Do you know which phylum you belong to? In this science project, you will investigate the diversity of the animal life around your home and try to figure out… Read more

Fishing Line Strength

Science Fair Project Idea

Scientific Method

If you like to fish and you'd rather not be telling the story of "the one that got away," then this is a project for you. What combination of properties makes for the best fishing line? Here are some suggestions for getting started on your background research into fishing line properties: knot strength, abrasion strength, shock strength, tensile strength, limpness, controlled stretch, and desired range of visibility (Dodson, 2006). Choose the properties that you think are most important, and… Read more

Flavor That Food! Exploring the Science of Marinades

Science Fair Project Idea

Scientific Method

Have you ever tasted a delicious burger and wondered how it got so much flavor? Maybe you have heard your family talk about marinating foods before cooking or grilling them. A marinade is a mixture of seasonings used to flavor or tenderize food. Most cooks have strong opinions about the best way to marinate their favorite food, be it a large steak or a tofu burger. In this cooking and food science fair project, you will run controlled tests to see what factors are most important in making a… Read more

It’s fall, which means flu season. We all know that washing hands a few extra times a day can help keep colds and flu at bay, so we wash hands frequently and use a paper towel…then another one, maybe even three or four to dry them off. Because who likes to go out with wet hands in cold fall weather, right? But could there be a way to conserve some of that paper, and get a paper towel to go the extra mile, allowing you to dry your hands with just one single sheet? This… Read more

Football Field Goals: Going the Distance

Science Fair Project Idea

Scientific Method

When watching a football game, have you ever wondered why some kicks lead to a successful field goal and others do not? There are a lot of variables at play in a game of football, and many of them are related to physics. One variable that can affect whether a field goal is successful is distance. In this science project, you will explore how field goal success rate is affected by distance from the goalposts. What will be the best distance for you to kick some field goals? Grab a football, head… Read more

Football: Punting

Science Fair Project Idea

Scientific Method

When the punter is trying to hit the "coffin corner" (within the opposing team's 10-yard line), out of bounds, what is the best angle to kick the ball for correct distance and maximum "hang time?" (For more information on the physics involved, see: Gay, 2004, Chapters 4 and 5.) Read more
