Instructional Materials
Pictures of marijuana, opium, alcohol, tobacco, snuff; charts, markers, observation sheets

Lesson Development – ABC Model
A – Anticipation (Warm-up / Starter)
Time: 5–10 minutes
Teacher asks students if they have heard of substances like marijuana or alcohol and what they think happens to people who use them. Students share in pairs and with the class.

B – Building Knowledge (Main Lesson Body)
Time: 25–30 minutes

Learners’ Activities (Expanded):
Teacher begins by asking students if they have ever seen adults using substances like alcohol or tobacco and what they know about them. Teacher explains that some substances are bad drugs because they can harm the body and mind.

The teacher introduces common bad substances:

  • Marijuana – a green leafy substance that can affect thinking and health.
  • Opium – a sticky substance from certain plants that can make people addicted.
  • Alcohol – drinks like beer, wine, and spirits that can hurt the liver and body.
  • Tobacco – smoked in cigarettes or pipes, harmful to lungs.
  • Snuff – powdered tobacco taken through the nose, dangerous to health.

Students observe pictures, illustrations, or short videos (if available) of these substances. The teacher explains local names for each substance (e.g., marijuana – “weed,” tobacco – “snuff,” etc.) to make examples familiar.

Students work in small groups to:

  1. Discuss where these substances are usually found in the community (markets, bars, farms, homes).
  2. Create a chart in their notebooks with two columns: one for the substance name and the other for its local name.
  3. Share findings with the class and discuss why knowing the names helps them avoid harmful substances.

Practical Activity:

  • Students role-play scenarios where someone offers them a bad substance, practicing saying “No” and explaining why it is harmful.
  • Students draw a “Do Not Touch” poster for bad substances in their notebooks or on chart paper.

Assessment Checks:

  • Teacher asks each student to identify one bad substance and its local name.
  • Teacher asks students to explain why it is harmful.
  • Observation of group discussions, role-play, and chart work to ensure understanding.

Notes (Expanded & Detailed):

  • Reinforce that bad substances are harmful, can make someone sick, addicted, or unable to think clearly.
  • Emphasize that knowing local names helps children avoid them in the community.
  • Encourage students to share examples of where they have seen these substances locally and discuss real-life consequences in age-appropriate language.
  • Highlight that staying away from bad substances keeps the body and mind healthy and ensures safety at school and home.

C – Consolidation (Conclusion & Assessment)
Time: 5–10 minutes
Summary: Students share one example of a bad substance and explain why it is harmful. Teacher reinforces the importance of avoiding these substances.

Evaluation Method (Expanded)
Exit slip/quiz: Students write one bad substance and its local name. Teacher collects slips and provides oral feedback.

Assignment (Expanded)
Students ask their parents or guardians about bad substances in the community and write a short list with local names.

Follow-up Activity: In Week 33, students will learn about the effects of bad substances on individuals, family, school, and society.

Differentiation / Inclusive Strategies: Use pictures and local names to support memory and recognition. Pair students for discussion and sharing.
