The nature and behaviour of matter is a central theme both scientifically and culturally, so it is included in most primary school science curricula. The subject is one of the many conceptual areas in science in which children's understanding, before and after formal teaching, has been explored. It is still a fruitful research area in order to foster more effective teaching and meaningful learning in the school setting. Nevertheless the children, I think, can be introduced to a first idea of the structure of matter, namely it is possible to lead primary school pupils to grasp the properties and behaviours of the objects depend on the inner structure of materials they are made.
Children are interested in knowing what the objects are made of.
They're also able to grasp the properties and behaviour of the object, depending on the inner structure of materials they are made of. Sets of coordinated science activities have been prepared aimed at helping children to develop scientific abilities and training them to grasp concepts like mass, volume density, energy, thermal processes and electric current and voltage. All that gave the children the opportunity to realize that different tools must be used for different manufacturing. Hereafter an example is given of the interest the children were showing during their work, and the experiments carried out to satisfy their curiosity. I do it again without bungling.
