This activity explores an image of a wildlife overpass crossing a major highway, which serves as a phenomenon for learning about habitat fragmentation and conservation.
A wildlife overpass is a bridge that allows wildlife to move safely over a road. It is one way to reconnect habitats fragmented by human structures and activities. Reconnecting habitats expands the overall area available to wildlife and can support more biodiversity.
The “Educator Materials” document includes background information and implementation suggestions for using the image as a phenomenon. The “Student Handout” includes the image and background information.
Student Learning Targets
- Examine images of phenomena, make observations, and ask questions.
- Collaborate with peers on ideas, ask questions that require higher levels of reasoning, and develop deeper understanding of concepts.
- Describe how wildlife overpasses can reconnect habitat fragments and support more species.
