Chemistry science fair projects. What's your favorite reaction?

Our bodies constantly run hundreds of thousands chemical reactions. Working on one of the chemistry science fair projects would be just a natural choice. :)

Chemistry is one of the most important sciences. Comfort of our lives depends on it. Most of the modern materials we use in our household would not exist without it.

Chemical reactions are everywhere. Some of them are fierce and dangerous - such as fire or explosion. Some are slow and invisible but extremely important - such as conversion of carbon dioxide into calcium carbonate - the process that constantly happens in the oceans promoted by ocean living organisms and responsible for the part of the carbon cycle in the biosphere.

The methods of modern chemistry are very complex, including predictions of material properties using supercomputers. Chemistry projects described on this page are much more simple and can be safely carried at home usually using readily available compounds. (COMING SOON)

Natural Dyes.

This group of chemistry science fair projects study natural dyes. They are coming from different organic and non organic sources. The most common dyes sources are plants, flowers and berries. Can you name some of them?

Their properties can be very different. We'll find out how to extract natural dyes, how they react to the bases and acids. Can we use them as pH indicators?

Some of them are more stable and others are easily destroyed by UV radiation from the sun light. We can make good study of that.

Some of them made of many pigments and can be separated using chromatography


Titration is a method that you can use to find out the unknown concentration on certain chemical compound in the complex substance. This method is one of the most used in analytical and biochemistry. Titration itself can be good science project otherwise you could use it as a method in some of the biology projects. Vitamin C science project uses titration method to compare vitamin C concentration in different substances.

The Rate of the Reaction

In this projects we simply mix different compounds and see what happens. We try to identify products of the reactions and chemical or physical factors that can change the speed of a chemical reaction. We'll find if there are any differences between inorganic reactions and reactions that are promoted by complex organic molecules called enzymes.

Absorbents and Adsorbents.

What is common between disposable diapers and activated coal? What's the difference? How to clean the water? How far water can travel up a cotton thread? Is water going to "climb" higher up the wool thread or piece of blotting paper? All this important questions are investigated in this group of chemistry experiments.
