2.3 The Science Curriculum of Elementary School
Science at the elementary school level is taught as an integrated discipline called "Nature". In the "Nature" course, scientific attitudes, creative thinking, and decision-making are emphasized. The objectives of the course are itemized as follows: 1) to acquire rudimentary methods of inquiring about the nature and utilize them in solving problems; 2) to understand facts and concepts about natural phenomena and apply them to explaining natural phenomena; 3) to build interests and curiosity in natural phenomena and scientific inquiries and to develop scientific attitudes; and 4) to understand that science influences technological development and is strongly related to our life.
The contents include not only knowledge such as matter, motion and energy, life, and earth, but also inquiry activities such as observation, classification, measuring, communicating, predicting, using models, interpreting data, experimentation, and so forth. The chemistry contents in the science curriculum of elementary school are summarized in Table 2.
