Science Fair Project Idea
thumbnail If you have ever prepared a cup of coffee or tea with sugar, you have probably seen that the grains of sugar quickly dissolve and completely disappear in hot water. But sugar is not the only type of solid that can readily dissolve in a liquid. In fact, there are some types of rocks that can be dissolved by common liquids. It might be hard to imagine large, hard rocks being eaten away by some ordinary fluids, right? But it actually happens all the time! In this geology science project, you will… Read more

thumbnail Have you ever looked in the kitchen cupboard and found a container of tiny white grains, but you were not sure if they were sugar or salt? They look very similar. How could you tell them apart? Well, you know that sugar and salt taste very different. Taste is actually called a property, and properties are used to describe and identify different materials. Properties can also be used to physically separate things. In this science project, you will use different properties to create a way… Read more

thumbnail Gelatin! It's hard to think of another food that is used as frequently on the dinner table as off. You can find it in all sorts of sweet foods, from ice cream, yogurt, and gummy bears, to marshmallows and yellow colorings for sodas. Off the table, it shows up in glues, photographic paper, playing cards, crepe paper, medicine capsules, hair gels, and professional lighting equipment. From the kitchen to the theater—what a range of uses! In this cooking and food science fair project, you'll… Read more

thumbnail Maple syrup is deliciously gooey and great on breakfast foods like pancakes and waffles. But it has another amazing property. It can be turned into maple candies with a range of textures, like sticky maple taffy or molded maple sugar candy. In this science fair project, you will investigate how the temperature that maple syrup is heated up to affects what type of maple syrup-based candies can be made. Read more

thumbnail "Slurp...plop!" Recognize that sound? You might if your family usually serves jellied cranberries for the holidays. Jellied cranberries are thick, like gelatin, and retain the shape of the mold in which it was placed, which might mean Aunt Sue's turkey mold or even the shape of the can if you buy one of the popular canned versions. Taking a bite of wiggly jellied cranberries can be a fun addition to a delicious meal, but cranberries can also be served as a sauce. Both versions use the same… Read more

thumbnail Imagine if instead of spooning up a bowl of soup, a container of yogurt, or a cup of pudding you could just pick up and pop in your mouth a round, mess-free, ball-like blob of one of those. It might feel like snacking rather than eating a meal! In this food science project you can try exactly that. The simple step-by-step directions will lead you through trying a fun cooking technique called reverse spherification to turn yogurt into semi-solid balls, which are called "raviolis."

thumbnail Soap comes in many varieties and forms—from bars to bottles to boxes. The uses for soaps are just as expansive—from cleaning our hands, hair, and faces to a variety of household cleaning jobs, such as dishes or laundry. One thing all these different soaps have in common is their chemical origin; they were all made by mixing fat or oil with a strongly basic solution, such as lye. In this chemistry science project, you will carry out the chemical steps needed to transform coconut oil… Read more
