- Responding variable: Elasticity of rubber / Length of rubber strip
- Controlled/Fixed variable: Mass of weight, size of rubber strip
|
| Operational Definition |
If the minimum weight required for the rubber strip to fail to return to its initial length is larger, then the rubber strip is more elastic. |
