How Blue is Your Sports Drink?
Science Fair Project Idea
Scientific Method
Do you read the list of ingredients in foods and drinks before you buy them at the grocery store? If you do, you may have noticed that many of the items, especially colored drinks, contain dyes with names such as FD&C Blue 1, Red 40, or Yellow 5. But how much dye is needed to create all these colors? In this chemistry science project, you will build a simple spectrophotometer that is able to measure the concentration of colored chemicals in solutions. You will test your device by measuring… Read more
Make Your Own Markers
Science Fair Project Idea
Scientific Method
Do you ever wonder how markers are made? Where do all of those colors come from? Many of the colorful dyes we use come from plants. Could you create vibrant colored natural dyes? Could you turn these dyes into art supplies? You can! In this science project, become a scientist and engineer and make your own marker using homemade plant dye! Read more
Water to Fuel to Water: The Fuel Cycle of the Future
Science Fair Project Idea
Scientific Method
Solar cells are popping up on rooftops everywhere these days and are a model for clean, renewable energy. Did you ever look at those solar panels and wonder how we can get electricity produced by solar cells when the sun is not shining? It is a great question because solar panels do not produce electricity when it is dark outside. One strategy to overcome this challenge is to store the energy produced by solar cells during the day in the form of a fuel that can be used at a later time. In this… Read more
Make Your Own Shampoo and Test How It Performs!
Science Fair Project Idea
Scientific Method
Do you love it when your hair is nice and fresh? The key to keeping your hair nice and clean is to use a good shampoo. But with so many different products in the store, how do you know which one works best for you? In this science project, you will put a variety of shampoos to the test, including your own homemade organic shampoo recipes. Do you think these will perform better than a store-bought product?

Crime Scene Chemistry: Determine the Identity of an Unknown Chemical Substance
Science Fair Project Idea
Scientific Method
Picture this situation: An elderly woman is rushed to the hospital complaining of severe abdominal pain, tinnitus, and lethargy. Suspecting a drug interaction, the emergency room doctor starts questioning her. The doctor learns that the woman takes no medicines except aspirin for her arthritis. Since she cannot swallow pills well she takes a powdered form of aspirin which she buys in bulk and keeps in a plastic container in her kitchen next to her baking goods. She had just finished a day of… Read more
Discover Chlorophyll Variety in Different Plants Using Paper Chromatography
Science Fair Project Idea
Scientific Method
Do you like to analyze stuff and finding out what it is made of? An analytical chemistry method, called chromatography, allows you to separate mixtures of compounds and to identify each individual compound within the mixture. Chromatography is used by many scientists, for example food scientists, forensic scientists, or organic scientists to analyze all kinds of mixtures such as food, blood, or medicine. In this project, you will be using paper chromatography to analyze the pigments from… Read more
Which Liquid Works Best for Evaporative Cooling?
Science Fair Project Idea
Scientific Method
When we get hot, we sweat. Sweating helps cool us down. When the water evaporates, it removes energy from our bodies. This sort of evaporative cooling can also be used to cool homes using what are referred to as swamp coolers. In some cases, these coolers may be more energy-efficient than traditional air conditioners. In this chemistry science fair project, you will find out which liquid works best for evaporative cooling.

Big Pieces or Small Pieces: Which React Faster?
Science Fair Project Idea
Scientific Method
Some chemical reactions occur explosively fast, others may occur almost imperceptibly s-l-o-w-l-y. This project explores what effect the particle size of the reactants has on the speed of a chemical reaction: production of carbon dioxide gas by an Alka-Seltzer® tablet. Read more
How Electricity Changes pH in Salt Solutions
Science Fair Project Idea
Scientific Method
You have probably heard the saying that "water and electricity don't mix." Well, in this chemistry science fair project you will mix them, to create two solutions, one basic and one acidic. The apparatus is very simple, but the chemistry is complex and offers many avenues for exploration. Read more
How Do You Get Heat from a Supercooled Solution? Explore the Chemistry Within Hand Warmers
Science Fair Project Idea
Scientific Method
You're at the high school football game and it's getting pretty chilly as the sun goes down. You're determined to keep cheering for your team, but your hands are freezing—have you ever tried hand warmers? The chemistry within these little packets is pretty cool. Hand warmers provide a unique and fun way to study the chemistry of crystal formation and heat generation. By pressing a button in a pouch, which contains a supercooled solution, you start a rapid exothermic (heat-producing)… Read more
