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

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 In this project, you'll learn how to isolate DNA from onion cells, separating it from other cellular components in a manner that still preserves its structure and sequence. In the end, you'll have enough DNA to see with the unaided eye, and you'll be able to spool it to demonstrate its strand-like structure. Read more

Has a milk-based soup, sauce, or gravy ever curdled on you (formed lumps) as you were preparing it? Curdling is the process of coagulation that occurs where the proteins in the milk clump together. Sometimes curdling is desirable—for example, if you want to make a delicious cheese or yogurt—but if you are trying to make a milk-based soup or gratin, or if you're adding milk to a hot drink, curdling is very unwanted because you lose the smooth, creamy texture. Nobody likes clumps and… Read more

thumbnail OK, spill the beans, what's your favorite bean-rich food? Burritos? Chili? Or maybe you prefer the spicy Indian stew of lentils, known as dal? But what about fried tofu? Soymilk? Or peanut butter and jelly sandwiches? Did you know those foods come from beans as well? Beans are important to the diets of many people, and in this cooking and food science fair project, you'll learn how the liquid that beans are cooked in affects how quickly or slowly they soften.

thumbnail On a hot summer day, don't you just love opening a can of your favorite soda pop and taking a deep drink? The bubbles in the soda tickle your tongue's taste buds and propel the ingredients to your palate and nose so that you get a kick of flavor. But how do the bubbles, fizz, and taste get into the water? In this cooking and food science project, you will work with baking soda, citric acid, and sugar to create a your own soda pop. Once you develop your recipe, try it out on your friends and… Read more

thumbnail Many people you know probably have an opinion about the kind of milk they like to drink—some like it thin and refreshing, others like it thick and rich. Milk can be bought with different fat concentrations, but other than that, it's all the same. Or is it? This science fair project raises a few interesting questions about the other contents in milk. Do all milk products have the same protein concentrations? Do cows produce different types of milk during different stages of lactation?… Read more

Project Idea
thumbnail Have you ever wondered how yogurt is made and what makes some yogurts different from other yogurts? You may have noticed that most yogurt containers advertise that the yogurt contains "live cultures." This means that there are living bacteria in the yogurt! These amazing bacteria can turn plain old milk into a yummy yogurt treat. In this science project, you will investigate whether the bacteria affect what the yogurt feels, tastes, and smells like by making your own yogurt at home! Read more

thumbnail A plate of spaghetti, meatballs, and marinara sauce is a delicious and comforting meal. It's also an inexpensive meal, because it only costs about $12 to feed a family of four. And it's easy to make when you're on the go and need to eat a quick, but healthy dinner. Just boil a big pot of water, throw in your favorite pasta, cook for 11 minutes, drain, and top with meatballs and warm marinara sauce. Quick and cheap! But sometimes it feels like forever when you are waiting for water to boil,… Read more
