Science 8 Unit E: Freshwater and Saltwater Systems (Social and Environmental Emphasis)
Earth is sometimes described as the water planet: more than two-thirds of Earth's surface is covered by
oceans and freshwater features. By exploring examples of aquatic systems, students learn about the dynamic
nature of these systems and the interaction of landforms, sediments, water and climate. Students also investigate
factors affecting the distribution and health of living things in aquatic environments, and the supply and
quality of water for human use.
- How do water, land and climate interact?
- What are the characteristics of freshwater and saltwater systems?
- How do water systems affect living things, including humans?
The following concepts are developed in this unit and may also be addressed in other units at other grade levels.
- water quality
- water-borne materials
- erosion and deposition
- stream characteristics
- continental drainage systems
- ocean basins
- glaciers and icecaps
- adaptations to aquatic ecosystems
- human impact
Knowledge, skills and attitude outcomes are found in the Alberta Learning Science 7-8-9 curriculum.
Students will have the opportunity to apply information from their web research through the
