- The basis of investigation
- Interpreting Results
- Changes in the natural world
- Accidental Discoveries
Principles of Experimentation

- Ensure experiment is safe
- Design a control experiment
- Experiment must be fair
- Sample size
- Random selection
- Others must be able to replicate experiments
- Double blind testing
