thumbnail What do pizza, milk shakes, and ice cream sundaes have in common, besides being delicious and loaded with calories? You might be surprised to learn that these foods, because they contain dairy products, cannot be eaten by the majority of people around the world. Dairy products contain the sugar molecule lactose, and the majority of people on the planet slowly begin to lose the ability to digest lactose after the age of 2. In this human biology and health science fair project, you will… Read more

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

thumbnail Do you hate shots? Do you complain about paper cuts? Imagine if you had to give yourself shots a couple of times a day, as well as prick your finger, on purpose, even more frequently. Of course, if you have diabetes you do not have to imagine this; it is your reality. People who have diabetes usually need to keep close track of how much sugar is in their blood (called their blood glucose levels)by testing a drop of blood from a finger prick. If there is too much sugar in their blood, some… Read more

Prerequisites Some familiarity with electronic circuits and using breadboards would be helpful, though it is not required for this project. Completion of a basic chemistry class is also recommended before trying this project.
Material Availability A pump and other electronics parts must be specially ordered to do this project. See the Materials and Equipment list for details. Estimated project time includes shipping of specialty components.
Cost Average ($40 - $80)
Safety Some parts of the circuit can get warm during normal operation. Do not leave the circuit operating when unattended. Be very careful with your wiring to prevent short circuits from happening; short circuits can get very hot and cause plastic parts of the circuit to melt.

thumbnail While looking at a package of dry yeast it is hard to believe that the package has organisms in it that are alive. But add the right ingredients and presto, the mixture becomes a bubbly, oozing, mess of life! What are the right ingredients? What does that yeast need to become active? Do this science project and figure it out for yourself! Read more

Science Fair Project Idea
Pennies are bright and shiny when they're new, but become quite dull with time. What causes such a drastic change? Oxygen in the air combines with the copper in the penny to form copper oxide, which makes the penny look dull and dingy. You can make the pennies look like new again by soaking them in an acidic solution, like vinegar. Vinegar dissolves the copper oxide, making the pennies look like new. It turns out, however, that the same process that makes the pennies shiny has bad consequences… Read more

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

Science Fair Project Idea
Plants need nitrogen to build proteins and nucleic acids to grow healthy stems and leaves. Though the Earth's atmosphere is made up of 79% nitrogen, the form of nitrogen found in the atmosphere cannot be used by plants. In this experiment, you will compare plants grown without nitrogen fertilizer to plants grown with nitrogen fertilizer. Read more
