Science Fair Project Idea
thumbnail Apple pie is one of America's traditional desserts. It can be enjoyed on its own or with a scoop of vanilla ice cream. The cool sweetness of the ice cream combines with the warm apples and flaky pastry to create a taste sensation. However, if the pastry that surrounds the apples is heavy or chewy then that can really affect how much you enjoy this treat. But how do you make a pastry that is light and flaky? In this cooking and food science fair project, you will find out by experimenting with… Read more

thumbnail Here's a riddle for you: What would a latté be without a froth of bubbly milk on top? Answer: Black coffee! And how about a pumpkin pie without the whipped cream? Answer: Sad. Delicious, edible foams are everywhere, from sodas, meringues, and soufflés to mousses and whipped creams. They provide a delicious, spongy contrast to the foods they accompany, and their airiness releases aromas that enhance the eating experience. So, what makes a good foam? One with high volume and lots of… Read more

thumbnail Imagine that you could make an important piece of laboratory equipment in your kitchen. With this science project idea, you can! You will create your own centrifuge out of a salad spinner and some putty. In science labs, centrifuges are used to separate different liquids and/or solids from each other. You can load your homemade centrifuge with samples and see how they separate. What do you think happens to melted butter in a centrifuge? Read more

Science Fair Project Idea
Fresh whipped cream is the final touch for many delectable desserts. One issue with fresh whipped cream is that it has to be used soon after it is made, especially if it is at room temperature, or it starts to collapse into goo. This is a problem for its use in frostings or inside pastries as filler. Whipped cream can be stabilized by adding unflavored gelatin. Stabilized whipped cream can be used at room temperature and it has a much longer life. But how much gelatin is just right? Try… Read more

thumbnail "Plastic made from milk" —that certainly sounds like something made-up. If you agree, you may be surprised to learn that in the early 20th century, milk was used to make many different plastic ornaments —including jewelry for Queen Mary of England! In this chemistry science project, you can figure out the best recipe to make your own milk plastic (usually called casein plastic) and use it to make beads, ornaments, or other items. Read more

thumbnail What is the first thing you do when you wake up on a cold, frosty morning? Snuggle down deeper under the covers? Animals, like puppies and piglets, do not like being cold either, but they do not have hands or blankets to wrap themselves up. So when animals get chilled, they change their behavior and do things like huddle—they curl up close to other animals. In this mammalian biology science fair project, you will see just how much huddling can help reduce heat loss. Read more

thumbnail Light interacts with matter in a variety of ways—it can be absorbed, reflected, refracted (bent), and scattered. The scattering of light explains why the sky is blue, why milk is white, and why the Mississippi River is called "The Big Muddy." In this biochemistry science fair project, you will make an electronic device to measure the amount of scattered light in milk. You will also use the device to track the activity of protease (a type of enzyme) in pineapple juice, based on its ability… Read more

Science Fair Project Idea
A delicious and quick lunch is a cup of tomato soup and a grilled cheese sandwich. Biting into the toasty, butter-soaked bread and gooey cheese is very comforting. But what makes the cheese melt so nicely? Do all cheeses melt this way? In this cooking and food science fair project, you will experiment with making and determining the best recipe for processed cheese. Read more
