With this unit, students focus on the impact that humans and human activities have on the environment. Students are asked to explore what a balanced ecosystem looks like and identify what some threats are to that balanced ecosystem. Since we live in a world where technology is a major part of our lives, students are also asked to explore and assess the impact of selected technologies on the environment. Students are also asked to consider the costs and benefits of selected strategies for protecting the environment.
The overall expectations are:
• Assess the impacts of human activities and technologies on the environment, and evaluate ways of controlling these impacts;
• Investigate interactions within the environment, and identify factors that affect the balance between different components of an ecosystems;
• Demonstrate an understanding of interactions between and among biotic and abiotic elements in the environment;
