Instructional Ideas

• Use the lesson extension activities as a research project

Classroom Considerations

• Lesson builds on previous lesson (Fairly Fundamental Facts about Forces and Structures)
• There is an associated activity for the lesson, which is the next installment in the series
• The third installment of a six-part series

Pros

• Includes a vocabulary list with definitions and links to other websites

Cons

• Lesson itself is very bland and not likely to hold student interest
