![]() ![]() Explain that students must first build a model habitat that includes a wooded area on one side, a vernal pool on the other side and a road running in between.Provide each team with their materials.Instruct students to start brainstorming and sketching their designs.Review the Engineering Design Process, Design Challenge, Criteria, Constraints and Materials.Discuss the topics in the Background Concepts Section.Hand out the Salamander Crossing worksheet, as well as some sheets of paper for sketching designs.Salamander has to remain damp to survive.Habitat must have a wooded area on one side, a vernal pool on the other side and a road running in between.Think about how your crossing will allow for this. Salamanders also have to remain damp in order to survive. Remember that you may need to build something to help guide salamanders to your crossing as well. Then, you will need to change your model into a salamander-friendly habitat by building a way for the salamander to get from the woods to the vernal pool without having to cross the road. You will first build a model habitat that includes a wooded area on one side, a vernal pool on the other side and a road running in between. You are a team of engineers working together to design a way to get a salamander safely from one side of the road to the other. If a roadway exists between these two habitats, they have to cross the road to reach this very important destination. In the springtime, adult salamanders leave their forest homes and return to vernal pools where they breed and lay eggs. ![]()
