Lesson Synopsis:
Students explore how animals have moved across landscapes in the past, how modern roads and cities create challenges, and how today’s wildlife crossings help protect migrating species. They examine early solutions like fish ladders and compare them to present-day bridges and tunnels used around the world. Finally, students imagine future wildlife crossings that blend ecological needs, emerging materials, and creative engineering.

‍

Learning Objectives:

• Explain why animals migrate and identify obstacles created by human development.
• Compare past and present wildlife crossing solutions and their purposes.
• Analyze how different species require different types of crossings.
• Generate future-focused ideas for wildlife crossings using creative design thinking.

‍

Build Challenge:
Students will design and build a model wildlife crossing that helps a chosen species safely travel across a busy human-made barrier.
