Make Your Own pH Paper
This is a simple "kitchen chemistry" project about acid/base chemistry. Scientists measure the acidity or alkalinity of a solution using a logarithmic scale called the pH scale. In this project you'll learn about the pH scale, and you'll make your own pH indicator paper using a pH-sensitive dye that you'll extract from red cabbage. You can use your pH paper to measure the acidity/alkalinity of various household solutions.

Paper Chromatography: Advanced Version 1
This project will teach you the basics of analytical chemistry, which is a must for students who want to go into chemistry or materials science. The molecules in objects we see all around us are constantly attracting each other. Different materials can be attracted or repelled depending upon their molecular structure. We can utilize the different attractive forces between substances to separate a mixture of compounds. Chromatography is a method to separate mixtures and identify each compound in the mixture. You will separate ink components found in different marker using a strip of paper, chalk and different liquids.

Paper Chromatography: Advanced Version 2
Chromatography is a method used to separate mixtures of compounds and to identify each compound in the mixture. You may have separated the different inks in a black marker by using a strip of paper and water. There are many different types of chromatography: paper, thin-layer, high-performance thin-layer, gas, and more. You will be using paper or thin-layer chromatography to analyze the compounds from different plants. Chromatography is used by analytical chemists, organic chemists, and many other types of scientists since it is so easy and affordable. If you want to get a head start in chemistry, this is a great way to do so.

Potions and Lotions: Lessons in Cosmetic Chemistry
Did you know that cosmetic companies employ teams of specialized chemists
to develop and test each new line of make up, perfume, lotion, or soap?
Here's a project that lets you be the cosmetic chemist. It shows you how to manufacture your own lip gloss right in your kitchen using a short list of simple ingredients. Check it out and then apply some creative cosmetic science in your own experiment.

Race Your Marbles to Discover a Liquid's Viscosity
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.

Just Keep Cool—How Evaporation Affects Heating and Cooling
When we get hot, we sweat. The physiological role of sweat is to 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. Evaporative cooling is also a potential source of energy waste in the kitchen because it increases the time it takes to heat water. In this chemistry science fair project, you will study how a variety of things cool down, whether for better or worse, using the process of evaporation.

Cold Pack Chemistry: Where does the heat go?
Instant cold packs are popular with coaches and parents for treating minor bumps and bruises. The instant cold packs are not pre-cooled—you just squeeze the cold pack and its starts to get cold. So how does it work? In this chemistry science fair project, you will investigate the chemical reaction that occurs in instant cold packs.

Saturated Solutions: Measuring Solubility
*
A solution consists of a
solute dissolved in a
solvent. A solution is
saturated when no additional solute will dissolve in it. You'll need a gram balance, a 100 ml graduated...
