The reproduction theme, on the other hand, is quite specific to life science classes. Teachers in all science disciplines should examine the themes to determine their applicability to the classes they teach. It is important to realize that even though this strand is called basic concepts and knowledge, it should not be treated as a list of items that students will memorize. This strand focuses on developing student understanding by blending content and process, highlighting the connections among scientific ideas. In the elementary grades, sophisticated concepts are introduced at developmentally appropriate levels of complexity, establishing meaning and use of unifying concepts and processes.
Students experience the excitement of discovery.
In the upper grades, students continue to build a repertoire of science experiences, enhancing the development of scientific learning by establishing the overall picture of scientific ideas. Inquiry involves the use of scientific reasoning and critical thinking to develop an understanding of science by combining processes and scientific knowledge. This strand addresses students' ability to conduct inquiry and develop an understanding about scientific inquiry, enriching their knowledge of science. Inquiry is the foundation for the development of content, and it teaches students the use of processes of science that enable students to construct and develop their own knowledge. In the elementary grades, students begin to develop physical and intellectual abilities by mastering skills and attitudes through scientific inquiry.
