Instructional Ideas

• Place learners in groups before class to maximize design time
• Set up a model biomechanical joint so scholars can reference it

Classroom Considerations

• Both the activity and extension require a mechanical joint with quick release pin and one with parts
• Need an air muscle for the extension

Pros

• Includes discussion questions to use before, during, and after the activity, as well as an extension activity
• Provides specific roles for each member of the group
• Comes with background information and step-by-step instructions for teachers

Cons

• None
