Science Fair Project Idea
thumbnail Have you ever been to a buffet and found yourself surrounded by a wide variety of taste sensations? People are generally able to discern five basic tastes: sweet, umami (also known as savory), salty, sour, and bitter. How sensitive is a person's tongue for these basic tastes? Is it easier to detect some flavors at low concentrations compared to others? In this human biology science project, you will find out by exploring your taste thresholds for sweetness, saltiness, and sourness. Get ready to… Read more

Science Fair Project Idea
thumbnail Did you know that your body needs a certain amount of iron in order to stay healthy? Iron can be found in much of what you consume each day. Almond meal—frequently used in cookies—is just one example of an iron-rich food. However, only a small fraction of the iron in food gets absorbed by the body, partially because the body can only absorb dissolved iron. In this project, you will study whether the acidic environment in your stomach helps dissolve iron. You will use a color-based… Read more

Time Required Average (6-10 days)
Prerequisites None
Material Availability This science project requires an iron test kit, available from [# Link Name="Chem_p090.7" Value="HtmlAnchor" #]. The Time Required estimate includes time for obtaining materials. Actual experimental time is only a few hours.
Cost Average ($40 - $80)
Safety The chemicals in the test kit could cause irritation if not handled properly. Be sure to wear gloves, safety goggles, and work in a well-ventilated area. Adult supervision is recommended. The small amount of sulfites contained in the iron indicator tablets may cause an allergic reaction in people who have asthma.
Science Fair Project Idea
thumbnail Which type of orange juice has the most vitamin C? In this science project, you will learn how to measure the amount of vitamin C in a solution using an iodine titration method. You will compare the amount of vitamin C in three different types of orange juice: homemade, premium not-from-concentrate, and orange juice made from frozen concentrate. Which do you think will have the most vitamin C? Read more

Science Fair Project Idea
thumbnail Are oranges highest in vitamin C when they are fresh from the tree (or, in a pinch, the grocery shelf)? Does the amount of vitamin C in an orange change over time, after it has been picked? In this science project, you will find answers to these questions by measuring the amount of vitamin C in a solution using an iodine titration method. Read more

Science Fair Project Idea
thumbnail The clothes you wear are made of fibers that come from many different sources. Some fabrics are made from natural fibers, and some from manufactured or totally synthetic fibers. In this science fair project, you will explore how different fiber types react with dye. Are you dye-ing to find out which works best? Read more

Science Fair Project Idea
thumbnail Have you or one of your pets ever been sprayed by a skunk? Hopefully not, but if you have, you probably know that the smell can be very unpleasant and hard to get rid of. There are many "folk remedies" for getting rid of skunk scent, but if you ever do get sprayed by a skunk, how will you know which one to try? In this science project, you will test the ability of various mixtures to remove the bad scent from rags that have been contaminated with bottled skunk scent, and determine which one… Read more

thumbnail Everything on our planet is connected together, linked by a giant recycling system called the biogeochemical cycle. It is an amazing process. You can actually investigate how our planet recycles and reuses everything needed to support life by making a small model of the biosphere. What will be important to include in your miniature system so that it can support different types of life? Read more

Science Fair Project Idea
Many essential chemical reactions and natural biochemical processes occur in liquid solutions, so understanding the chemical properties of liquid solutions is fundamentally important. This project asks the basic question, how much of a substance can dissolve in water, for three different substances: ordinary table salt, Epsom salts, and sugar. 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
