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

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

Scientific Method
Many disposable diapers contain a polymer, called sodium acrylate, which is useful for absorbing water. Do background research to learn about sodium acrylate, and how it reacts with water. Make sure that you understand the terms hydrophilic, polarity, hydrogel and hydrogen bonding. Cut out the middle, padded section of a disposable diaper. Cut this into equally-sized square pieces, approximately 10-12 cm on a side. Remove some of the stuffing material so that you can staple the open… Read more

Scientific Method
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

Scientific Method
How do you like your mashed potatoes? Thin and whipped smooth? Or thick and mashed into chunks? Your mouth checks out not just the taste of your food, but its viscosity, or how it flows on your tongue, every time you take a bite! In this science fair project, you'll learn what viscosity is, and how to measure it in common liquids around your home. Read more

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

Scientific Method
This is a modern version of a classic experiment by Jacques Charles on the volume of a gas at different temperatures. Charles discovered the relationship between volume and temperature of gases that now bears his name. This project shows you a simple method for re-creating this famous experiment. Read more
Science Fair Project Idea
Scientific Method
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
Scientific Method
You know that water can exist in three separate phases: solid (ice), liquid (water), and vapor (steam). To change from one phase to another, you simply add (or remove) heat. When water boils, what happens to molecules (for example sugar or salt) that are dissolved in the water? Do they boil off too, or do they stay behind? Read more

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
