Rationale
An estuary provides an excellent place for students to study the Nature of Science in the marine environment.
It's easy access allows students to get out into into the field to experience the difficulties in marine research and the time it takes to collect data while allowing them to come to the conclusion that scientific discoveries do not occur overnight and that hypothesis and scientific generalisations take a long time to become a reality.
Teachers Information
This booklet was written for draft Multistrand Science syllabus topics The Nature of Science and Matter and Materials
NATURE OF SCIENCE
Science is a human activity involving us all as we attempt to understand the world around us. The empirical mode of thought embodied in science provides one way of viewing our world. Students should. experience this empirical approach and be encouraged to develop a thoughtful, logical and
thorough approach to everyday life. To do this they should examine various views about the nature of science, its methods and processes.
Many aspects of this topic could be undertaken in conjunction with studies in other core topics or optional areas. An alternative approach could be the development of an introductory unit based on this topic.
MATTER AND MATERIALS
We are surrounded by an immense diversity of natural materials some of which man has adapted for his benefit. In addition he has developed new materials and applied these to the service of man. This interaction between man and his environment is crucial to our way of life.
Students should have an understanding of the structure, properties and uses of a range of materials both natural and synthetic. He should relate the materials, through a knowledge of their properties, to their everyday usage. The student should appreciate the reasons man chooses particular materials for specific usages. He should have a knowledge of some of the technologies involved and the impact of these technologies. As a consequence of the study of this topic the student should acquire a better appreciation of man's adaptation of these
materials.
These aims may be achieved by a variety of teaching approaches e.g. by a traditional geological and chemical development or
by a thematic study of a particular natural resource being transformed into a finished article. Irrespective of the approach pursued, the laboratory should form a focus for the treatment of the topic and students should acquire hands-on experience with a range of materials being studied.
The materials studied should include examples from each of the following three groups: ores, metals and alloys; non-metallic elements and inorganic compounds; organic compounds and polymers.
Students must be given the opportunity to do Field Work - Example in an estuary for this process, skill and affective objectives to be achieved.
