The aim of the natural sciences is to discover the laws that rule the world (Büchel, 1992). The focus lies hereby on the natural and not on the social world, although the differentiation is not always simple. There are historically three core areas of the natural sciences: chemistry, biology and physics. Nevertheless this is not a final list of research areas, since many other disciplines were later born out of these. As more knowledge is created, more specific questions arise. This leads to the fact that early natural scientists were generalists from today’s perspective, and later specialized in newly emerging disciplines such as astronomy in the beginning, different engineering disciplines later, and rather recently (i.e. in the last century) created fields such as robotics or bionics.

Making Electricity

Making electricity Just as electricity can make magnetism, so magnetism can make electricity. A dynamo is a bit like an electric motor inside. When you pedal your bicycle, the dynamo clipped to the wheel spins around. Inside the dynamo, there is a heavy


Electromagnetism Electricity and magnetism are closely related. You might have seen giant steel electromagnets working in a scrapyard. An electromagnet is a magnet that can be switched on and off with electricity. When the current flows, it works like a magnet; when the current


What is electricity? Electricity is a type of energy that can build up in one place or flow from one place to another. When electricity gathers in one place it is known as static electricity (the word static means something that does not move);
