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

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.
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.
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.
