Watershed Connections: Where Everyone Lives Downstream
Science and Technology, Grade 8
Human-Environment Interactions: Understanding Matter and Energy
Describe how knowledge of the properties of fluids can help us to understand and influence organisms in the natural world, and to design and operate technological devices and to evaluate how efficiently different devices make use of these properties.
1. Relating Science and Technology to Society and the Environment
1.2 assess the impact of fluid spills on society and the environment, including the cost of the cleanup and the effort involved.
Understanding Earth and Space Systems
1. assess the impact of human activities and technologies on the sustainability of water resources;
2. investigate factors that affect local water quality;
3. demonstrate an understanding of the characteristics of the earth’s water systems and the influence of water systems on a specific region.
2. Developing Investigation and Communication Skills
2.2 investigate how municipalities process water (e.g., obtain it, test it, and treat it) and manage water (e.g., distribute it, measure consumption, and dispose of waste water)
3. Understanding Basic Concepts
3.2 demonstrate an understanding of the watershed as a fundamental geographic unit, and explain how it relates to water management and planning.
3.3 explain how human and natural factors cause changes in the water table (e.g., lawn watering, inefficient showers and toilets, drought, floods, overuse of wells, extraction by bottled water industry)
Geography of Canada, Grade 9, Academic (CGC1P)
Geographic Foundations: Space and Systems
• demonstrate an understanding of the regional diversity of Canada’s natural and human systems;
• analyze local and regional factors that affect Canada’s natural and human systems.
Building Knowledge and Understanding
– explain how human activities (e.g., agricultural and urban development, waste management, parks development, forest harvesting, land reclamation) affect, or are affected by, the environment;
– assess how the effects of urban growth (e.g., development on former farm lands, destruction of wildlife habitats, draining of marshes) alter the natural environment;
Science, Grade 9 Applied (SNC1P)
Biology: Sustainable Ecosystems and Human Activity
B1. analyze the impact of human activity on terrestrial or aquatic ecosystems, and assess the effectiveness of selected initiatives related to environmental sustainability;
B2. investigate some factors related to human activity that affect terrestrial or aquatic ecosystems, and describe the consequences that these factors have for the sustainability of these ecosystems;
B3. demonstrate an understanding of characteristics of terrestrial and aquatic ecosystems, the interdependence within and between ecosystems, and the impact humans have on the sustainability of these ecosystems.
B1. Relating Science to Technology
B1.1 analyse, on the basis of research, how a human activity (e.g., urban sprawl, use of pesticides and fertilizers, creation of pollution, human interaction with wildlife) threatens the sustainability of a terrestrial or aquatic ecosystem [IP, PR, AI, C]
Sample issue: Pesticides and fertilizers are used to increase the productivity of land. However, run-off flows into water bodies and leaches into groundwater, poisoning the water or altering its chemical balance and affecting aquatic ecosystems.
Sample questions: How does the draining of wetlands for new subdivisions affect localwater birds and plants that thrive in marshes?
How does untreated waste released into rivers or lakes affect fish and animals that eat the fish? How does the introduction of Atlantic salmon or other sport fish affect indigenous lake trout and brook trout?
Physical Geography: Patterns, Processes and Interactions, Grade 11, University/College Preparation (CGF3M)
• explain how the earth provides both a habitat for life and a resource for society;
• evaluate the impact of natural systems on people and their activities;
• evaluate the impact of human life on the environment;
• explain the importance of stewardship and sustainability as guiding principles for human use of the physical environment.
– describe the flow of matter and energy through ecosystems (e.g., hydrologic cycle, carbon cycle) and explain the relationship of these flows to landforms, climate, soils,and vegetation;
– evaluate the impact of human activities (e.g., deforestation, the burning of fossil fuels, fertilizer use) on natural cycles (e.g., the carbon, nitrogen, or phosphorus cycles);
– analyze how selected human activities affect a local environment (e.g., farming and soil erosion, vehicle use and air pollution);
– illustrate (e.g., in a case study) how the concept of sustainability is applied in a local environment (e.g., through watershed management, wildlife management, forestry or fishery management).
– analyze ways in which human activities may increase or decrease the risks from natural hazards (e.g., floods, avalanches, tornadoes);
