Science Fair Project Idea
thumbnail Here is a riddle for you: what kind of rock grows? The answer is: rock candy! This delicious candy is actually crystallized sugar and you can "grow" it from a sugar-water solution. In this science fair project you'll learn how to grow your very own rock candy and determine if using seed crystals changes the growth rate of your sugar crystals. Read more

thumbnail Have you ever wondered why bubbles form when you mix soap and water? Is it possible to mix soap and water without making bubbles? Medical doctors actually study similar questions when they treat patients who have too much gas trapped in their digestive system, which can cause pain and bloating and also signal a serious medical problem. Some drugs, including one called simethicone, can help relieve extra gas in the digestive system. In this science project you will find out how simethicone… Read more

Science Fair Project Idea
Have you ever wondered how fun toys like Silly Putty, Gak, and Slime are made? These products are so much fun because of the properties of polymers, which make them delightfully bouncy, stretchy, sticky, moldable, breakable, hard, soft, and just plain fun! In this science project you can be the developer of your own putty product by changing the ratio of ingredients to change the physical properties of your putty polymer. By describing the physical properties of your results, you can choose… Read more

Science Fair Project Idea
If you browse through a candy cookbook, you might notice that many of the recipes call for corn syrup in addition to sugar. Both sugar and corn syrup are sweet, so why do you need corn syrup if you already have sugar? In candy making, corn syrup is known as an interfering agent. But what does this mean and how does it work? You can find out for yourself by making two batches of rock candy, one with corn syrup and one without. For example, you could alter the science project by replacing 1… Read more

Science Fair Project Idea
thumbnail Do you enjoy eating smoothies packed full of berries and other tasty fruits? Or maybe you like drinking a creamy milkshake with peanut butter, chocolate, and bananas. Often, smoothies and milkshakes are tasty to us because of the sugar in them. But did you know there are different kinds of sugar? Some ingredients in a smoothie can have more than one kind of sugar in them, and our bodies process each kind of sugar differently. In this science project, you will measure the concentration of… Read more

Science Fair Project Idea
thumbnail Have you ever noticed that the salt you are using says it is "iodized"? Iodine is an important micronutrient, which means we need it in small quantities to be healthy. Because iodine is rare in many people's normal diets, it is added to table salt. Then when people salt their food, they are also adding this important micronutrient. In this food science project, you will use some kitchen-friendly chemistry to investigate which types of salt have iodine added (in the form of iodide) and which do… 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
