Adsorption: Dyeing Fabrics with Kool-Aid

Science Fair Project Idea

Scientific Method

Have you ever wondered how your clothes get their color? Dyeing textiles is a very complicated process and involves a lot of chemistry. Not only are the properties of the dye and fabric important, but the dyeing conditions also have to be exactly right to get optimal color adsorption. Curious about how it works? In this science project, you will color wool with Kool-Aid® and explore the chemistry of dyeing. 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

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

What Sugar And Tea Does a Kombucha Biofilm Prefer?

Science Fair Project Idea

Scientific Method

You may have seen kombucha at the grocery store marketed as a healthy food choice. Did you know this drink is made with a special biofilm that ferments sugar into the tangy, fizzy drink? How does it do that? In this experiment, you'll learn how to make your own kombucha from a biofilm and what tea or sugar substrates you can change! Read more

Boyle's Law: Pressure vs. Volume of a Gas at Constant Temperature

Science Fair Project Idea

Scientific Method

This is a modern version of a classic experiment by Robert Boyle on the compressibility of gases. Boyle discovered the relationship between pressure and volume of gases that now bears his name. This project shows you a simple method for re-creating this famous experiment. Read more

Do Oranges Lose or Gain Vitamin C After Being Picked?

Science Fair Project Idea

Scientific Method

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

Excess Volume: Investigate the "Shrinking Liquids" Effect

Science Fair Project Idea

Scientific Method

Cooking, washing, and many industrial processes involve the mixing of liquids. How liquids behave when they are mixed is dependent on many factors. Sometimes, the mixing behavior of liquids can be quite surprising! For example, when you mix 50 mL of one liquid with 50 mL of another liquid, you might not end up with a 100 mL mixture! In this science project, you will explore this phenomenon, which we call the "excess volume" of mixtures. How do you think your mixing volumes will… Read more

Explore How Chromatography Can Unmix Mixtures

Science Fair Project Idea

Scientific Method

Did you know that mixtures can be unmixed? Chromatography is an analytical technique in chemistry to separate mixtures and identify each of its individual compounds. In this project, you will separate ink dyes found in different markers using a strip of paper, chalk and different liquids. By comparing different chromatography substrates and solvents, you will learn how different attractive forces between substances can affect the separation of a mixture into its individual components.

Getting a Bang Out of Breath Spray: Studying the Chemistry and Physics of a Small Explosion

Science Fair Project Idea

Scientific Method

Hold onto your hats! In this science fair project, you will make a device that sends a film canister across the room with a small chemical explosion. The energy for the explosion is derived from the combustion of ethanol. You will determine the launch velocity of the canister, as well as devise ways to study changes in gas pressure and volume due to the explosion. This science fair project is sure to take your breath away! Read more
