Two experiments will be conducted in the chemistry laboratory from 12:00 until 17:00: “Alchemic Transmutation, Or How To Change Metal Into Gold” (we shall repeat the experiments conducted at the turn of the 16th and 17th centuries by Michał Sędziwój, who conducted experiments at the court of Emperor Rudolph II) and “Why Should A Nail Be Covered In Grease, Namely A Little About Rust” (through which something can be learned about metal corrosion).
Further stands with experiments will be positioned at various points at the Copernicus Science Centre in hours of 10.00-17.00: Liquids and snots, namely hydrogels. The simplest example of a hydrogel, namely a polymer saturated with water is jelly, while others are contact lenses, dressings for burns, implants and cosmetics. It will be possible to make a hydrogel individually at this stand.
E secrets, namely a fun guide to food colourings
Red, yellow, blue… - coloured food dyes are natural or artificial chemical agents. They are added to food to recover the initial colour for products which is lost in the production process, reinforce the colour or to add colour to naturally colourless food. Dyes enable food to gain tasty fresh colours and attract the attention of even the most demanding consumer.
Chemical bonding, namely building a molecular model
Chemical bonding is any permanent combination of two atoms. A minimum of two electrons are needed to create a typical chemical bond, usually one from each of the atoms being combined. This stand will show how molecules arise and how to build a molecular model.
The great C60, namely we are building a fullerene
Fullerenes are molecules creating an empty block with an even number of carbon atoms, which look like a football. These structures, discovered more than 30 years ago, are still of interest to scientists. Here, it is possible to build a large model of a C60 molecule and to personally assemble and take away a small paper model.
Why is rain not salty and other water experiments from BASF
This stand will show what impact pollution has on the lives of living organisms, conducting a simple experiment with cress. Additionally, you will find out which materials are most suitable for filtering water and check whether everything can be filtered. In the next experiments, you will see what dissolves in water and what does not and you will look for the answer to the question of why rain is not salty. A personal experiment kit prepared by the chemical corporation BASF enables as many as eight experiments to be conducted.
The chemical laboratory is the first of four which we shall open at the Copernicus Science Centre by the end of 2011. In November, we shall open the biology laboratory, whereas, in December, we shall open the physics laboratory and the robotics workshop. The laboratories will be open to organized groups during the week and to everyone over the age of 13 at weekends.
