Instructional Ideas

• Bring in springs and projectiles to help the material come to life

Classroom Considerations

• Requires prior knowledge of applying and solving formulas
• Presentation includes a lot of material that would probably be best presented over multiple days to prevent overwhelming pupils

Pros

• Uses color coding to emphasize vocabulary and formulas
• Provides diagrams that are easy to understand

Cons

• None
