What interactions exist in the environment around us? How do human activities and technologies impact the interactions and the structure of the environment and ecosystems? These questions are answered in the Grade 7 - Unit 1: "Interactions in the Environment"
unit. This activity packet includes activities, readings, lesson plans, a unit overview, assessments and rubrics that can be used to address the following Grade 7 Ontario Science expectations:
- 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;
This packet also addresses the following big ideas:
- Ecosystems are made up of biotic (living) and abiotic (non-living) elements, which depend on each other to survive;
- Ecosystems are in a constant state of change. The changes may be caused by nature or by human intervention;
- Human activities have the potential to alter the environment. Humans must be aware of these impacts and try to control them.
