Project Title: Cell Observation and Microscope Practice
Objective: Use a microscope to observe cells and practice slide preparation.
Project Instructions:
- 1. Prepare a temporary slide of a plant cell (onion peel or leaf).
- 2. Observe using a light microscope and record what you see.
- 3. Label visible cell parts in a simple drawing.
- 4. Estimate cell size using a simple scale method.
- 5. Consult your coach where necessary.
Evidence to Submit:
- • Labeled drawing of the cell.
- • Notes on microscope parts and functions.
- • Size estimation method and result.
Submission
Part C: Training Others
Teach a peer microscope use and cell identification.
Guidance:
- • Demonstrate safe microscope handling.
- • Guide the learner to focus and observe.
- • Help them label key cell parts.
Reflection:
- • What was clear to the learner?
- • What steps needed repetition?
- • What support do you need from your coach?
