Science - Gr 7

Interactions in the Environment

In this Science unit, students will have the opportunity to discover that ecosystems are made up of biotic (living) and abiotic (non-living) elements, which depend on each other to survive. Students will need a parent or other helper to guide them through these activities and help them discuss the reflection questions.

Students will demonstrate an understanding that ecosystems are in a constant state of change and that the changes may be caused by nature or by human intervention. Students will also be asked to consider how human activities have the potential to alter the environment and that humans must be aware of these impacts and try to control them.
