Science Fair Project Idea

Engineering Design Process

When you need a calculator, what do you use? A physical calculator? An app on your phone? A web browser? What features does the calculator have? Does it just do basic arithmetic (addition, subtraction, multiplication, and division)? Can it do other mathematical functions, like square roots or exponents? Can you use parenthesis? Does it have a backspace button? That is a lot to consider for a seemingly very simple device or program! For a computer science project, can you write your own… Read more

You Want Fries With That? The Science of Crispy Potatoes

Science Fair Project Idea

Scientific Method

The first bite of a fresh-picked apple, the crunch of morning toast, the deep cut into rich, flaky layers of baklava, the pleasing snap of a chip. Besides being delicious, what do these foods have in common? They're crisp. They have a brittleness that causes them to shatter in your mouth when you first bite into them. It's a sensation that many people enjoy. Making potatoes crispy requires some extra cooking steps, as you'll discover in this food science project, but the results are well worth… Read more

Yuck, What Happened to My Apple? How Food Wrappings Affect Spoilage

Science Fair Project Idea

Scientific Method

Have you ever eaten half an apple and saved the other half for later, only to find that, by time you were ready to eat it, the apple did not look as tasty anymore? It may have turned brown and shriveled, and, if left out long enough, it may have spoiled. Do you think you could have prevented the other half from spoiling, or made it spoil less, if you had stored it differently, such as in the refrigerator in a food wrapping? In this cooking and food science project, you will investigate which… Read more
