Fascinating world of chemistry

The desire to discover, create and understand the world has been accompanying almost every human being from their early age. However, we are so engrossed in the daily grind that we do not have the opportunity to fulfil our dreams. The Lower Silesian Science Festival comes in handy! The panel called "Fascinating World of Chemistry" is replete with events in disparate formats form laboratories to workshps. All this gives you a chance to carry out plenty of experiments. You will surely feel like a real chemist!

 

EVERYDAY CHEMISTRY

 

Chemistry of coffee – how to make good coffee?

 

Coffee is one of the oldest and most popular stimulants, commonly used for energizing us. Nonetheless, the interpretation of myths describing the effect of coffee on the body leads to quite different conclusions. Scientific studies are giving us a clearer and clearer view on the health aspects of this stimulant and proposing new and unique uses of coffee extracts and coffee grounds. These aspects have a direct bearing on the way not only coffee beverages but also valuable pharmaceuticals and biofuels are made. Participants will also learn about how to make tasty coffee.

 

Black tea, white tea – chemistry in a cuppa

 

Many of us like to sit under a blanket in the evening, start a day with a cup of hot tea or drink it with a close friend. Is tea both tasty and healthy? Is there a difference between black and white tea? What about green and red? What chemical compounds are responsible for tea properties and how can we detect them? Multicolored tea infusions will reveal their secrets, including the color of their origins, the caffeine content, as well as the mysterious brown sediment on the cup (and a simple way to remove it).

 

CHEMISTRY AS A KEY TO NATURE

 

Recipe for life – from DNA to protein

 

The lecture concerns a DNA molecule, being a carrier of genetic information about the structure and functioning of a living organism. The construction of a DNA molecule and how the gene-regulated lifecycle is transformed into protein biosynthesis will be presented in an accessible way. The methods of DNA examination and genetic information analysis will also be discussed.

 

 

See what an eye doesn't see – how does the chemist learn about the world of particles and compounds?

 

What methods do contemporary chemists use? How do they work? Today's chemistry is experimental and theoretical alike. It assists in the interpretation of experimental results and predicts the effects of future experiments with varying degrees of precision. It is a science that deals with the study of the nature and properties of substances. It is possible because of advanced physical and chemical methods that enable us to see what we can't see with the naked eye.

 

JOY OF EXPERIMENTING

 

Free radicals – what are they? How can they be detected?

 

Free radicals are unpaired atoms, the excess of which causes atherosclerosis, cancer and premature ageing. Free radicals are generated in cells of living organisms by the process of cellular respiration. At the lab attendees will be able to familiarize themselves with the concept of free radicals, their influence on our health and the methods of their detection.

 

 

We invite all those who have open mind, vivid imagination and hunger for knowledge. We know our readers are full of these qualities!
