The purpose of this activity is to introduce students to the concept of the engineering design process and to teach them how to apply it. In "Broken Bones," students will explore the steps of the engineering design process. They will first receive some background instruction about biomedical engineering or bioengineering. Then they will learn about material selection and material properties by using a guide created for them. Students will then break into small groups and brainstorm. Each student group is assigned a specific design problem. Students will be given materials and asked to create a prototype. To finish, students will communicate their solution through a poster presentation.
