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

How Bright Is Your Glow Stick? Measure It!

Science Fair Project Idea

Scientific Method

Objects that glow in the dark hold a special place in the imagination of both children and adults. The lights go out at night, but these odd things refuse to disappear. Where does the light come from? Do they work in any climate? In this science fair project, you will make a very simple electronic device to measure the light given off by luminescent materials. The device will be used to study how temperature affects luminescence. Read more

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

Is Plant-Based Milk as Protein-Packed as Dairy Milk?

Science Fair Project Idea

Scientific Method

What kind of milk do you drink in your household? Do you drink 2% dairy milk, whole dairy milk, or plant-based milk like almond milk or soy milk? Have you ever considered why you drink it? As more sustainable and alternative food options become increasingly available, people are interested in the nutritional value of plant-based foods. The US government dietary guidelines state that dairy milk is a good source of protein. Are plant-based milk sources also a good source of protein? In this… Read more

Diaper Science: How Hydrogels Absorb Water

Science Fair Project Idea

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

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.

How Fast Does an Alka-Seltzer® Tablet Make Gas?

Science Fair Project Idea

Scientific Method

This is a straightforward, fun project to measure the rate of the chemical reaction that occurs when Alka-Seltzer® tablets are plopped into water. You will track the volume of carbon dioxide gas produced at regular intervals after the reaction begins. How does changing the temperature of the water affect the production of gas? Read more

Proving Charles' Law: Volume vs. Temperature of a Gas at Constant Pressure

Science Fair Project Idea

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

Solar-powered Chemistry: Study Chemical Reaction Rates in Ultraviolet Beads

Science Fair Project Idea

Scientific Method

Most of the ultraviolet (UV) light produced by the Sun is blocked by the atmosphere, but some UV light does still reach Earth. It can be detected using electronic devices, but can also be detected with something called UV beads. UV beads contain a pigment that changes color when they are exposed to ultraviolet radiation from the Sun. In this chemistry science fair project, you will use UV beads to study how temperature affects the rate at which they lose their color. Read more

Saturated Solutions: Measuring Solubility

Science Fair Project Idea

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
