Part of Lesson Plan: Bill of materials (green lesson)

Activity Overview / Details

(To save paper, display the handouts and picture on an overhead or SMART Board and then email

your students copies of the material!)

1. Display the visual in Reproducible #1 – Railroad Tracks . Ask students to imagine that the tracks are no longer used and are going to be torn out and demolished. You can hand out Reproducible #2 – Railroad Tracks Discussion Questions and have the students answer questions individually, in small groups, or as a class. You may want to lead a class discussion without handing out the sheet. Try to guide the students towards answering that the wood and metal from the railroad tracks could be recycled or reused in another capacity. These discussion questions should be used to encourage brainstorming and to get students to begin thinking about alternative building options.
