Lesson Focus

Students will learn about different kinds of animal crossings engineered to help protect wildlife and the ways civil engineers can take wildlife migration into account when developing in wildlife habitats. They will construct a model of a salamander migration area with a road passing through it and design a crossing to get the salamanders safely to their breeding grounds.
