This project shows how mathematical probability sometimes contradicts our intuition. Despite the fact that there are 365 days in a year, if you survey a random group of just 23 people there is a 50:50 chance that two of them will have the same birthday. Don't believe it? Try this project and see for yourself.

Have you ever wondered if some shapes have certain "sounds" to people, even if they have different native languages? For example, does everyone match certain physical characteristics, like sharpness or roundness, with certain sounds? Are there certain human sounds with meanings that can cross the language barrier? In this science project you will investigate this by testing the Bouba-Kiki Effect—will it turn out that abstract visual properties can be linked to sound?

Here's a project idea for all of you bakers out there. What happens if you try your favorite muffin recipe with different types of flour (e.g., white, whole wheat, rye, soy, etc.)? Think of ways you can measure the results. How would you measure the density of a muffin? A kitchen scale would definitely be useful for this project, both for measuring the results and for portioning out the batter for equal-sized muffins. What other measures might be of interest?

Oooey gooey cheese...yum! Who doesn't like a slice of warm pizza straight from the oven? There's nothing quite like a slice of pizza and a glass of milk, so what makes pizza so great? The cheese! But did you know that making cheese is all about science and chemistry? In this science fair project, you will learn more about the science of cheese making and what kind of milk works best. Try this science fair project and you'll learn about science and get something yummy to eat afterward!

What do pizza, milk shakes, and ice cream sundaes have in common, besides being delicious and loaded with calories? You might be surprised to learn that these foods, because they contain dairy products, cannot be eaten by the majority of people around the world. Dairy products contain the sugar molecule lactose, and the majority of people on the planet slowly begin to lose the ability to digest lactose after the age of 2. In this human biology and health science fair project, you will…

You've probably noticed that the price of gasoline has been going up and up lately. Heating oil will probably cost more this winter than last winter, too. Using good insulation material is one way to conserve energy and save money. What insulation materials work better than others?

There is nothing quite like the smell of fresh-baked bread to make your mouth water! As any baker can tell you, you cannot bake bread without yeast. Yeast actually eat sugar so that they can reproduce and make more yeast, and make bread dough rise. But can they use sugar substitutes to do this? In this science project you will get to investigate how well yeast grow with sugar substitutes as a food source. Pass the butter, please!

Do you know why enzymes are oftentimes called the workhorses of biochemistry? It's because they can speed up a wide variety of chemical reactions, and chemists and biologists use enzymes to do all kinds of jobs. In this project, pectinase, an enzyme frequently used in the food industry, will be used to extract juice from apples.

Have you ever seen pictures or videos of a roof being blown off a house during a hurricane or tornado? You might be surprised to hear that the roof is actually not pushed off by the strong winds but instead by the air inside the house! This can be explained by Bernoulli's principle, which states that fast-moving fluids or air, such as strong winds, have lower pressure than slow-moving air. In this activity you will demonstrate how balloons can be moved in a similar way. It is not quite as…
