Topic: Biotechnology and Genetic Modification
Lesson 1: Bacteria in Biotechnology and Genetic Modification
| Section | Details |
|---|---|
| Objective | – Explain why bacteria are useful in biotechnology and genetic modification. |
| Activities | Starter (5 mins): Show a short video or animation about biotechnology applications like insulin production. Main (25 mins): 1. Introduce biotechnology and genetic modification concepts. 2. Discuss why bacteria are commonly used: rapid reproduction, ability to make complex molecules, and presence of plasmids. 3. Highlight ethical considerations for manipulating bacteria. Plenary (10 mins): Students create a flowchart explaining how bacteria are used to produce a product like insulin. |
| Resources | Video on biotechnology, diagrams of plasmids, flowchart templates. |
| Time | 40 minutes |
| Homework | Research an example of a product created using bacteria in biotechnology and explain the process. |
| Assessment | Class discussion and flowchart creation. |
| Past Paper Practice | IGCSE Biology 0610/21/M/J/19 Q4(a). |
Lesson 2: Advantages of Bacteria in Biotechnology
| Section | Details |
|---|---|
| Objective | – Discuss the advantages of bacteria in biotechnology, including ethical and practical considerations. |
| Activities | Starter (5 mins): Present a scenario: Why might scientists prefer bacteria over animals in experiments? Main (25 mins): 1. Explore the practical benefits: easy growth, rapid reproduction, plasmid presence. 2. Discuss the minimal ethical concerns compared to using animals or humans. 3. Provide examples of biotechnology applications, e.g., antibiotic production, genetic modification of crops. Plenary (10 mins): Students list advantages of bacteria and share their findings with the class. |
| Resources | Case studies, infographics comparing bacterial and animal-based methods. |
| Time | 40 minutes |
| Homework | Write an argument supporting the use of bacteria over higher organisms in genetic modification research. |
| Assessment | Group activity and homework arguments. |
| Past Paper Practice | IGCSE Biology 0610/42/M/J/17 Q6(b). |
Key Notes for Teachers:
- Use real-life examples like insulin production or antibiotic creation to contextualize the topic.
- Encourage ethical debates and discussions about genetic modification.
- Utilize visual aids like plasmid diagrams to clarify concepts.
