| Subject: Biology |
| Lesson Topic: state that globular proteins are generally soluble and have physiological roles and fibrous proteins are generally insoluble and have structural roles |
Learning Objective/s:
- Describe the structural differences between globular and fibrous proteins.
- Explain how solubility relates to protein function.
- Compare physiological roles of globular proteins with structural roles of fibrous proteins.
- Interpret a diagram contrasting a soluble globular protein and an insoluble fibrous protein.
|
Materials Needed:
- Projector or interactive whiteboard
- PowerPoint slides with diagrams
- Handout summarising key differences
- Sample protein models (clay or 3‑D printed)
- Exit‑ticket cards
- Markers and whiteboard
|
Introduction:
Begin with a quick image of a folded ball of yarn versus a long rope to spark curiosity about protein shapes. Ask students what they know about protein solubility and how it might affect function. Explain that by the end of the lesson they will be able to state the solubility characteristics and functional roles of globular and fibrous proteins.
|
Lesson Structure:
- Do‑now (5') – students list everyday examples of proteins.
- Mini‑lecture (10') – present definitions, solubility, and functional roles using slides.
- Guided comparison (10') – work through the provided table, fill missing entries in pairs.
- Diagram activity (10') – label a schematic of a globular and a fibrous protein, discuss.
- Think‑pair‑share (5') – answer: why must enzymes be soluble?
- Quick quiz (5') – Kahoot or paper quiz to check understanding.
- Exit ticket (5') – write one physiological role of a globular protein and one structural role of a fibrous protein.
|
Conclusion:
Summarise that soluble globular proteins perform dynamic physiological tasks, whereas insoluble fibrous proteins provide structural support. Prompt students to write a one‑sentence exit ticket linking solubility to function. Assign a short homework: find a real‑world example of each protein type and describe its role.
