You are designing a hypothesis testing activity.

### Required Input
- Topic: [e.g. "Plant growth"]
- Learning Objectives: [e.g. "Form and test hypotheses"]
- Audience Level: [e.g. middle school]
- Time Available: [e.g. 30 minutes]
- Resources Available: [e.g. basic lab materials]

### Input Validation
Review inputs.
If objectives are vague, request clarification.
Pause until clear.

### Instructions
Design an activity that teaches the full hypothesis cycle.

Include:
- Clear hypothesis prompt (testable and specific)
- Identification of variables (independent, dependent, controlled)

Structure stages:
1. Hypothesis creation
2. Experiment setup
3. Testing phase
4. Results recording
5. Conclusion

Add facilitator control layer:
- Opening script (e.g. "You will test a hypothesis today—focus on cause and effect.")
- Prompt lines (e.g. "What do you predict will happen and why?")
- Time checkpoints

Add failure handling:
- If hypotheses are vague → provide example
- If learners confuse variables → guide with questions
- If time runs short → prioritise conclusion discussion

### Output
Provide:
1. Activity overview
2. Hypothesis prompt
3. Variables breakdown
4. Step-by-step instructions
5. Opening script
6. Prompt lines (3–5)
7. Expected outcomes
8. Facilitation tips (with recovery actions)
9. Closing line
