The iodine clock reaction is a favorite demonstration reaction in chemistry classes. Two clear liquids are mixed, resulting in another clear liquid. After a few seconds, the solution suddenly turns dark blue. The reaction is called a clock reaction because the amount of time that elapses before the solution turns blue depends on the concentrations of the starting chemicals. In this chemistry science fair project, you will explore factors that affect the rate of the iodine clock reaction. Read more

thumbnail Did you know that your body needs a certain amount of iron in order to stay healthy? Iron is an essential part of the hemoglobin complex in your blood, which carries oxygen from your lungs to the rest of your body. It is also involved in many other biochemical processes in your body. Iron can be found in much of what you consume each day. In this chemistry science fair project, you will use a simple test kit that produces an orange-colored chemical in the presence of iron in a solution. The kit… Read more

thumbnail It's the bottom of the ninth, and you've spent a great afternoon at the ball game with a hotdog, a soda, and an ice cream in hand, but I'll bet you're not thinking about how many crops went into those classic baseball snacks. Sure, the bun contains wheat, but did you know that the hotdog might contain wheat, too? And soybeans may have been used to give that ice cream its perfectly smooth texture, while corn was likely used to sweeten the entire meal! Crops can be changed and added to processed… Read more

thumbnail As you know, vegetables not only taste good, but they are good for you. Many vegetables are a great source of vitamin C. Vitamin C is a water-soluble antioxidant that plays an important role in protecting the body from infection and disease. Humans do not make vitamin C on their own, so we must get it from dietary sources. Potatoes, like the ones shown in Figure 1, below, are one good source of vitamin C. Does cooking them affect how much vitamin C they have? In other words, if you boil a… Read more
