Learning science helps children to develop ways of understanding the world around them. For this they have to build up concepts which help them link their experiences together, they must learn ways of gaining and organizing information and of applying and testing ideas. This contributes not only to children’s ability to make better sense of things around them, but prepares them to deal more effectively with wider decision-making and problem-solving in their lives. Science is as basic a part of education as numeracy and literacy, it daily becomes more important as the complexity of technology increases and touches every part of our lives.
Learning science can bring a double benefit because science is both a method and a set of ideas, both a process and product. The processes of science provide a way of finding out information, testing ideas and see- king explanations. The products of science are ideas which can be applied in helping to understand new experiences. The
A. the importance of science in human development
B. the proper ways of teaching children science
C. the necessity for children to learn science
D. the correct attitude to science as a subject in primary education
