Topic: Risky Behaviors for HIV Infection
Sub-topic: High Risk, Low Risk, and No-Risk Behaviors; Review and Reinforcement
Learning Objectives
By the end of the lesson, students should be able to:
- Identify behaviors that increase the risk of HIV infection (high risk).
- Differentiate between low-risk and no-risk behaviors for HIV transmission.
- Reinforce previous lessons on health, hygiene, disease prevention, and lifestyle choices through discussions, practical activities, case studies, and role-play.
Previous Knowledge
Students already know:
• Basic understanding of HIV & AIDS transmission and prevention
• Importance of hygiene, nutrition, and physical health
Instructional Materials
• Textbook: General science textbooks for Grade 7
• Teaching aids: Charts showing HIV transmission, case study handouts, role-play materials, markers, and flip charts
• Students' notebooks and writing materials
Lesson Development – ABC Model
A – Anticipation (Warm-up / Starter)
Time: 5–10 minutes
Activity: The teacher will ask the class:
• Can you list some activities or behaviors that might increase the chance of contracting HIV?
• Are there activities that are safe and pose no risk?
The teacher will record their responses on the board.
Teacher’s Role: Guide brainstorming, correct misconceptions, and link student responses to HIV transmission facts.
Learner’s Role:
• Share ideas and experiences related to risky and safe behaviors.
• Participate verbally in discussion.
B – Building Knowledge (Main Lesson Body)
Time: 25–30 minutes
Teacher’s Role
- Introduce the Topic Clearly
- Start by reminding learners that not all behaviors carry the same risk for diseases like HIV/AIDS.
- Write the three categories on the board: High-Risk, Low-Risk, No-Risk.
- Ask students if they can guess examples before giving definitions.
- Explain High-Risk Behaviors
- Unprotected sexual intercourse: without the use of condoms increases chances of HIV and other STIs.
- Sharing needles: for drug use, tattoos, or injections with unsterilized syringes.
- Transfusion with unscreened blood: if blood is not tested for HIV.
- Multiple sexual partners: increases exposure risk.
- Local examples: Some Liberians may visit unlicensed clinics for injections or rely on traditional tattooing practices without sterilization.
- Explain Low-Risk Behaviors
- Behaviors that have a small chance of disease spread but are not completely safe.
- Examples: kissing (if open sores are present), sharing sharp objects like razors, and accidental contact with small amounts of blood.
- Clarify that casual contact such as hugging, shaking hands, or sharing utensils carries little to no risk, but misconceptions often cause stigma.
- Local myth correction: Some people believe HIV can be spread by mosquitoes — explain clearly that this is false.
- Explain No-Risk Behaviors
- Activities that have no chance of transmitting HIV/AIDS.
- Examples: attending school, playing football, dancing, sharing food, eating safe meals, talking, or living in the same household.
- Reinforce that friendship and kindness cannot spread HIV.
- Review and Reinforcement of All Subtopics
- Class Discussions:
Recap definitions of health, disease, hygiene, balanced diet, drug abuse, and exercise.
• Show how they all connect to preventing diseases like HIV/AIDS. - Practical Activities:
Handwashing Demonstration: Show proper steps using soap and clean water. Emphasize this as a daily preventive measure for many diseases.
• Exercise Routine: Lead learners in a short set of stretches, jumps, or football drills to reinforce the role of exercise in maintaining good health. - Case Studies (Real-Life Scenarios):
Example 1: A girl is pressured by her boyfriend to have sex without protection. What should she do?
• Example 2: A student cuts his finger in class. His friend wants to help. What is the safe way to do it?
• Example 3: Someone refuses to sit next to a classmate living with HIV. What is wrong with this action? - Role-Play Exercises:
Students act out situations showing how to refuse high-risk behaviors, promote safe practices, or correct false beliefs.
• Example: A peer offers a razor to share → one student refuses politely and explains why it is dangerous.
- Class Discussions:
Learners’ Activities
- Observation: Watch the teacher’s demonstrations of hygiene and safe practices.
- Participation in Discussions: Share what they know or believe about HIV/AIDS transmission, correcting myths together.
- Case Study Engagement: Work in small groups to discuss how they would respond to risky situations.
- Role-Play: Perform short skits modeling safe behavior, decision-making, and stigma-free attitudes.
- Practical Activity: Practice proper handwashing and participate in a short class exercise session.
- Identification Task: Give real-life examples from their own environment of high-risk, low-risk, and no-risk behaviors.
Assessment Checks
- Oral Classification Exercise: Teacher calls out a behavior (e.g., “sharing needles,” “playing football,” “hugging a friend”) and students answer whether it is High-Risk, Low-Risk, or No-Risk.
- Case Study Questions: Students explain how they would respond to each scenario given.
- Observation of Role-Play: Teacher notes if students demonstrate correct understanding of risk behaviors.
- Participation in Practical Activities: Check if students correctly wash hands or demonstrate exercise moves.
Notes (Expanded & Detailed)
- Reinforce that HIV is not spread by casual contact, which is a major myth in Liberia.
- Stress that informed decision-making (knowing risks, refusing unsafe practices, and choosing alternatives) protects students from disease.
- Highlight the importance of respecting and supporting people living with HIV to fight stigma and discrimination.
- Use local context:
• Many Liberians buy medicine or receive injections from informal sources → emphasize checking safety.
• Sachet alcohol or drug use may lead to risky behaviors → link back to substance abuse prevention. - Show how healthy lifestyle choices (hygiene, balanced diet, exercise, avoiding drugs, safe practices) all connect to stronger resistance against disease.
C – Consolidation (Conclusion & Assessment)
Time: 5–10 minutes
Summary:
• The teacher will ask the students to recall:
- High-risk, low-risk, and no-risk behaviors
- Key lessons from previous topics on health, hygiene, nutrition, disease prevention, and lifestyle choices
Evaluation Method (Expanded):
• Exit slip/quiz: Students will write short answers to:
- List three high-risk behaviors for HIV infection.
- Give two examples of low-risk behaviors.
- Name three activities that pose no risk of HIV transmission.
Teacher will collect and quickly review for understanding
• Provide oral feedback before class ends
Assignment (Expanded): Follow-up Activity:
• Create a chart categorizing common behaviors in your community into high, low, and no-risk for HIV.
• Prepare a short role-play demonstrating safe practices that prevent HIV transmission.
Differentiation / Inclusive Strategies
• Struggling Learners: Use simplified examples, visual aids, and peer-assisted activities.
• Advanced Learners: Research HIV statistics in Liberia and present findings to the class.
• Students with Disabilities: Provide tactile charts, peer support, and guided participation in role-plays.
