1. What kind of contents? – “Simple - Complex Science”
To accurately understand and interpret the world in which we find ourselves we must first correctly perceive it. What is meant by correct perception is to be able to systematically look at events and make connections. However, it is very difficult to systematically perceive all of the things that happen around us, particularly in childhood. This does not mean that we cannot accurately perceive the world in childhood or that it is not necessary to strive for this. In particular, the efforts we make at these ages are the key to a love of science in later years. If we can make students at that age understand how to think scientifically it will enlarge their imagination of the world and it will be make it easier for them to become inquisitive individuals. To approach the physical world in which we find ourselves we can simplify its complex structure without destroying its essence with experimental activities. What is
explained simply here is carrying out scientific activities with everyday materials. That is, materials and experimental activities that are planned from simple things. For example we can teach the lifting power of water with a tangerine and a bowl of water. Simplicity helps us to think correctly and also helps us to make connections between events. Thus students will be saved from their prejudice that "science is difficult" and discover the place that science has in our lives. Here the essence of simplicity is that it helps students get closer to perceiving and understanding complex events. This simplifying is not in opposition to the nature of science. Because "there is an absolute continuity between scientific facts (at the foundation) and scientific peaks" if we consider science at the peaks as fantastic telescopes, genes, neutral proteins we will be able to find complex science, but if we consider them at the level of physical reality (at the foundation) we can touch and feel them ... and we can help children approach the perceptual and conceptual world (Quéré, 2006).
