Week & Period: Week 22, Period 4
Topic: Substance Abuse and Physical Exercise
Sub-topic: Drug/Alcohol Abuse, Influencing Factors, Effects, and Exercise
Learning Objectives
By the end of the lesson, students should be able to:
- Explain the meaning of substance and drug abuse and identify influencing factors such as peer pressure, parental influence, and societal impact.
- Describe the physical, mental, social, and economic effects of drug abuse on the body.
- Explain the importance of physical exercise and give local examples, including school-based exercise activities.
Previous Knowledge
Students already know:
• Basic concepts of health, hygiene, and disease prevention
• Importance of maintaining a healthy lifestyle
Instructional Materials
• Textbook: General science textbooks for Grade 7
• Teaching aids: Charts illustrating effects of substance abuse, exercise equipment (balls, skipping ropes), videos on health impacts
• 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:
• Have you seen or heard of people using drugs or alcohol? How does it affect them?
• What activities do you do at school or home to stay healthy and fit?
The teacher will record their responses on the board.
Teacher’s Role: Guide brainstorming, correct misconceptions, and link responses to scientific understanding.
Learner’s Role:
• Share experiences or observations about substance use and exercise.
• Participate verbally and respond to questions.
B – Building Knowledge (Main Lesson Body)
Time: 25–30 minutes
Teacher’s Role
- Definition and Clarification
- Substance Abuse: Explain that it means using drugs, alcohol, or harmful substances in a way that damages health, behavior, or social life.
- Clarify the difference between use (e.g., prescribed medicine taken correctly, or moderate alcohol by adults) and abuse (taking too much, taking without prescription, or using illegal substances).
- Give common Liberian examples: misuse of alcohol (“gin bitters”), tramadol, marijuana, sniffing gasoline, cigarette smoking.
- Discuss Influencing Factors of Drug Abuse
- Peer Pressure: wanting to fit in with friends who drink or smoke.
- Parental Behavior: children copy parents or relatives who drink or smoke heavily.
- Societal Expectations: in some communities, alcohol is linked with celebration, “manhood,” or bravery.
- Availability of Substances: cheap alcohol sold in sachets or street corners; misuse of over-the-counter medicines like cough syrup or painkillers.
- Use case study: “A student begins skipping class because friends pressure him to drink palm wine after school.”
- Explain the Effects of Drug Abuse
- Physical Effects:
Damage to liver, lungs, kidney, and brain.
• Weight loss, fatigue, poor appetite.
• Increased risk of accidents. - Mental Effects:
Poor concentration, memory loss.
• Aggressive or unpredictable behavior.
• Addiction (constant craving, inability to stop). - Social Effects:
Family quarrels, broken friendships, violence.
• School absenteeism, dropping out.
• Antisocial behavior such as theft, fighting, or crime. - Economic Effects:
High medical costs for treatment of addicts.
• Loss of money to buy drugs/alcohol instead of food, school fees, or family needs.
• Reduced productivity in work and studies. - Link the four effects: Show a diagram on the board (circle divided into Physical, Mental, Social, Economic) and explain how they connect.
- Physical Effects:
- Introduce Physical Exercise as a Healthy Alternative
- Definition: any planned, regular activity that helps the body stay fit and strong.
- Types of Exercises:
Aerobic (endurance): running, walking, skipping.
• Strength: push-ups, carrying water buckets, climbing.
• Flexibility: stretching, bending, yoga-like movements.
• Balance/coordination: dancing, football, basketball. - Benefits of Exercise:
Improves strength, stamina, and coordination.
• Boosts mental health: reduces stress, improves focus in class.
• Prevents obesity, diabetes, hypertension.
• Provides positive alternatives to bad habits. - Local/School-Based Examples:
Football (very popular in Liberia).
• Running and racing during recess.
• Skipping with ropes made of rubber ties.
• Traditional cultural dances.
• Manual activities like sweeping the compound, carrying water, farming.
Learners’ Activities
- Observation & Listening: Look at teacher’s diagrams, listen to explanations, and observe exercise demonstrations.
- Discussion: Share examples of drug abuse cases they have seen or heard in their community, and suggest how to avoid them.
- Group Work: List 5 ways to avoid substance abuse (e.g., good friends, staying in school, joining sports teams, saying “No,” seeking guidance).
- Practical Activity: Participate in a 5-minute exercise routine in class (jumping jacks, stretching, short race in place).
- Role-play: Act out a short skit where one student refuses peer pressure to drink or smoke, choosing instead to join friends playing football.
Assessment Checks
- Oral Questions:
• “What is the difference between drug use and drug abuse?”
• “Name two factors that influence drug abuse in Liberia.”
• “List one physical and one mental effect of drug abuse.” - Class Activity: Ask students to work in pairs: one names a community scenario (e.g., a boy smoking marijuana), the other explains the physical/mental/social/economic effects.
- Practical: Observe students’ participation in the short exercise routine and ability to link exercise to good health.
Notes (Expanded & Detailed)
- Stress that healthy lifestyle choices (exercise, good diet, avoiding harmful substances) help students grow strong and succeed in school.
- Emphasize that drug abuse destroys future potential, while physical exercise builds a healthy, productive, and respected life.
- Use cultural context: football and dancing are positive social alternatives to drinking/smoking in youth groups.
- Reinforce peer refusal skills: encourage students to say “No” politely but firmly when offered drugs or alcohol.
- Connect to national relevance: Liberia faces health and social challenges from substance abuse; schools can play a key role in prevention.
C – Consolidation (Conclusion & Assessment)
Time: 5–10 minutes
Summary:
• The teacher will ask the students to recall:
- Factors influencing substance/drug abuse
- Effects of drug abuse on the body
- Benefits of physical exercise and local examples
Evaluation Method (Expanded):
• Exit slip/quiz: Students will write short answers to:
- Name two factors that may influence drug use among teenagers.
- State two physical and two mental effects of drug abuse.
- List three benefits of physical exercise and give examples.
Teacher will collect and quickly review for understanding
• Provide oral feedback before class ends
Assignment (Expanded): Follow-up Activity:
• Conduct a survey on healthy physical activities practiced by peers and write a short report.
• Create a poster showing the harmful effects of drug abuse and ways to prevent it.
Differentiation / Inclusive Strategies
• Struggling Learners: Use simple language, role-play, and visual aids to reinforce concepts.
• Advanced Learners: Research local and global statistics on drug abuse and present findings.
• Students with Disabilities: Provide tactile materials, peer support, and assistive visual aids for demonstrations.
