Instructional Ideas

• Give each group a different-sized balloon and compare results
• After pupils have worked to find a pattern between velocity and mass, challenge them to calculate the mass needed for a specific velocity

Classroom Considerations

• Expects at least a basic understanding of gravity and weight

Pros

• Adaptable to a wide range of grade levels
• Includes both teacher and student guides

Cons

• None
