Science 7
IE7.4
Analyze how ecosystems change in response to natural and human influences, and propose actions to reduce the impact of human behaviour on a specific ecosystem.
DM, CP
Indicators for this outcome
| (a) |
Identify evidence of ecological succession in ecosystems, using the concepts of pioneer species, climax community, primary succession, and secondary succession, and by identifying changes in plant and animal life in the ecosystem. |
| (b) |
Propose ecological questions to investigate arising from practical problems and issues (e.g., "What is the impact of clearing land for farming?", "How could a community prolong the life of its landfill site?", "How could a community reduce the amount of garbage it produces?", "What is the impact of a sports field being constructed in a particular location?"). |
| (c) |
Predict what a specific ecosystem (e.g., clear-cut forest, abandoned sports field, abandoned farm yard, abandoned rail line, ditch, driveway, or sidewalk) will look like in the future (e.g., 5, 10, and 25 years) based on characteristics of the area and long-term changes observed in similar ecosystems. |
| (d) |
Identify and refine questions and problems related to the effects of natural or human influences on a particular ecosystem. |
| (e) |
Select and synthesize information from various sources to develop a response to specific questions related to natural or human influences on a particular ecosystem. |
| (f) |
Propose a course of action or defend a given position on a local ecological issue or problem related to natural or human influences on a particular ecosystem, taking into account scientific, societal, technological, and environmental factors. |
| (g) |
Be sensitive and responsible in maintaining a balance between human needs and a sustainable environment by considering both immediate and long-term effects of their course of action or stated position. |
| (h) |
Provide specific examples to illustrate that scientific and technological activities related to ecosystems take place in a variety of individual or group settings, locally and globally, and by men and women from a variety of cultural backgrounds (e.g., individual and community gardening, impact studies done by environmental engineers, and research done by teams of international scientists). |

Project WILD Activity Guide
The 2002 Project WILD Activity Guide features activities designed to develop awareness, knowledge, skills and the environment. Through many of the activities, students are engaged in informed decision making in which they consider the impact of their actions on the ecosystem. Each multigrade activity includes objectives, method, background information, materials and procedures, as well as extension and evaluation ideas. The activity guide contains seven sections: Awareness and Appreciation; Diversity of Wildlife Values; Ecological Principles, Management and Conservation; People, Culture and Wildlife; Trends, Issues, and Consequences; and Responsible Human Actions. Teachers are encouraged to select and adapt activities that align with curriculum outcomes and meet the needs of students.
Project WILD activity guides are free to teachers who attend a Project WILD workshop. These workshops provide an opportunity to experience the activities and to actively plan how to use them in the classroom. A modest registration fee will cover workshop materials and expenses.

Our Incredible World Series
This video series examines an urban wetland. Jesse and Seka pursue a science project on biodiversity. They decide to survey the life in a cattail marsh to build a case to preserve the wetland. Through each episode in the series, Jesse and Seka learn about the species in the wetland, how to take data to substantiate their claims, how to classify the various species, how the various species adapt to live in the wetland and present their findings to city councillors and the land owner.
