SCIENCE 9-6
Unit 1: Biological Diversity
Biological diversity exists both between and within species on a global scale. This is a result of variations which are are maintained through processes of sexual and asexual reproduction. In this unit, students examine how the survival of individual species and propagation of variations through generations may be influenced by ecological and human-caused factors. Students also investigate the environmental impact of a loss of diversity.
Unit 2: Matter & Chemical Change
Different materials have different properties. In this unit, students are introduced to the study of chemical substances through laboratory investigations and formal studies of chemical theory, including ideas about elements and compounds, the periodic table, chemical nomenclature and simplified ways of representing chemical reactions.
Unit 3: Environmental Chemistry
Environments are often viewed from a physical and biological perspective but, to fully understand how they function, it is important to view them from a chemical perspective as well. A study of environmental chemistry helps students understand that chemical substances make up the underlying fabric of the world and are part of the process in all natural cycles and changes. Through this unit, students also become aware of the impact of man-made chemical substances on the environment.
Unit 4: Electrical Principals & Technologies
Electricity is required to power many of the devices, systems and processes that are part of our everyday lives. In this unit, students learn about electrical conversions and the societal and environmental implications associated with the production and use of electrical energy. Students create and modify circuits, and develop skills for evaluating technologies by comparing alternative designs in terms of their efficiency, effectiveness and environmental impact.
Unit 5: Space Exploration
Technologies have played an essential role in advancing our understanding of space and in the emerging use of space environments by humans. A study of space exploration provides an opportunity for students to examine how science and technology interact and to learn how one process affects the other. Students become aware that technologies developed to meet the challenges of space are applied to new purposes.
