| Section | Details |
|---|---|
| Objective | – Describe what an STI is and identify HIV as a pathogen that causes an STI. |
| Activities | Starter (5 mins): Ask students to define “infection” and brainstorm how infections can spread. Main (25 mins): 1. Define STIs and explain how they are transmitted through sexual contact. 2. Introduce HIV as a specific example of an STI and discuss its effects on the immune system. Plenary (10 mins): Students summarize the relationship between HIV and AIDS. |
| Resources | Presentation slides with definitions and diagrams showing HIV effects on the immune system. |
| Time | 40 minutes |
| Homework | Research and write a brief summary of the early symptoms of HIV and how it progresses to AIDS. |
| Assessment | Class participation in describing STIs and identifying HIV as a cause of AIDS. |
| Past Paper Practice | IGCSE Biology 0610/21/M/J/19 Q4(a). |
Lesson 2: Methods of HIV Transmission
| Section | Details |
|---|---|
| Objective | – Describe the methods of HIV transmission. |
| Activities | Starter (5 mins): Ask students if they know how diseases can be transmitted between individuals. Main (25 mins): 1. Explain the primary methods of HIV transmission: blood transfusion, sharing needles, unprotected sexual contact, and from mother to child during childbirth or breastfeeding. 2. Discuss misconceptions about HIV transmission. Plenary (10 mins): Students create a flowchart summarizing how HIV spreads. |
| Resources | Diagrams and infographics showing HIV transmission pathways. |
| Time | 40 minutes |
| Homework | Write a list of common myths about HIV transmission and research the facts. |
| Assessment | Students’ ability to explain transmission methods accurately during the activity. |
| Past Paper Practice | IGCSE Biology 0610/31/O/N/18 Q3(b). |
Lesson 3: Controlling the Spread of STIs
| Section | Details |
|---|---|
| Objective | – Explain how the spread of STIs, including HIV, can be controlled. |
| Activities | Starter (5 mins): Show a short video or infographic on STI prevention methods. Main (25 mins): 1. Discuss methods to prevent STIs, including: practicing safe sex (e.g., using condoms), regular testing, avoiding sharing needles, and ensuring blood products are screened. 2. Emphasize the importance of education and awareness campaigns in reducing STI transmission. Plenary (10 mins): Quick quiz: Students suggest ways to spread awareness about STI prevention. |
| Resources | Educational videos, handouts on STI prevention strategies. |
| Time | 40 minutes |
| Homework | Design an awareness poster on how to prevent HIV and other STIs. |
| Assessment | Students propose and explain practical measures to prevent STI transmission. |
| Past Paper Practice | IGCSE Biology 0610/22/M/J/20 Q6(c). |
