Week 1 Lesson Duration: 45 minutes
Week & Period: Week 1, Period 1
Topic: Science & Scientific Knowledge
Sub-topic: Definition of Science, Knowledge of Facts vs. Scientific Knowledge, Scientific Methods
Learning Objectives
By the end of the lesson, students should be able to:
- Define science and differentiate it from general knowledge of facts.
- Explain the differences between factual knowledge and scientific knowledge.
- Describe the steps and attitudes involved in the scientific method, including observation and experimentation.
Previous Knowledge
Students already know:
• Science is related to learning about the natural world.
• Some basic observations about objects and events in their environment.
Instructional Materials
• Textbook: General science textbooks for Grade 7
• Teaching aids: Charts showing scientific methods, experiment kits, projector/board
• 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:
• What do you understand by the term “science”?
• Can you give an example of a fact and a scientific observation?
The teacher will record their responses on the board.
Teacher’s Role: Guide a short brainstorming session and correct misconceptions.
Learner’s Role:
• Share their existing ideas about science.
• Respond verbally and participate in warm-up discussion.
B – Building Knowledge (Main Lesson Body)
Time: 25–30 minutes
Teacher’s Role
- Definition and Foundation of Science
- Explain clearly that science is the systematic study of the natural world through careful observation, questioning, and experimentation.
- Use simple analogies: e.g., “When you see rain falling, you may wonder why it happens. Science helps us find answers by studying clouds, air, and water.”
- Clarify Factual Knowledge vs. Scientific Knowledge
- Factual knowledge: simple truths (e.g., “The sun rises in the east”).
- Scientific knowledge: tested and supported by evidence (e.g., “The sun appears to rise in the east because the Earth rotates on its axis”).
- Stress the three features of scientific knowledge:
- Evidence-based (supported by proof)
- Reproducible (same results if repeated)
- Tested by experimentation
- Introduce the Scientific Method
Break down into clear steps learners can recall:- Curiosity & Attitudes: asking “Why?” or “How?”
- Observation: using the senses carefully.
- Experimentation: testing ideas by trying them out.
- Recording Results: writing down findings.
- Analysis: looking for patterns or explanations.
- Drawing Conclusions: explaining what was learned.
- Practical Examples (with Liberian Contexts)
- Environmental Study: Students observe rainfall patterns during rainy season.
- Agricultural Practice: Farmers testing different types of soil to see which grows rice better.
- Classroom Experiment: Mixing sugar in hot and cold water to see which dissolves faster.
- Health Example: Washing hands before eating reduces sickness (tested in school health programs).
Learners’ Activities
- Engage in guided discussions on the meaning of science.
- Ask questions to clarify differences between facts and scientific knowledge.
- Observe a simple demonstration/experiment done by teacher (e.g., “Which dissolves faster: sugar in hot or cold water?”).
- Record observations and notes in their notebooks.
- Work in pairs or small groups to identify scientific method steps in the example experiment.
Assessment Checks
- Ask individual students: “Give me one example of a fact, and one of scientific knowledge.”
- Conduct a quick exercise: Write the steps of the scientific method on the board in random order, and ask learners to rearrange them correctly.
- Group activity: Teacher describes a situation (e.g., “A farmer wants to know which rice seed grows faster.”), and learners identify:
- Observation
- Experimentation
- Recording
- Conclusion
Notes (Expanded & Detailed)
- Stress that science is built on curiosity (asking questions), honesty (reporting results truthfully), and careful observation (not rushing).
- Use local and familiar examples so learners see science as part of their daily lives:
- Testing which water source is cleanest for drinking.
- Observing plant growth with and without fertilizer.
- Monitoring how quickly clothes dry under sun versus shade.
- Remind learners: Science is not only for scientists in labs; it is for everyone—students, farmers, health workers, and communities.
C – Consolidation (Conclusion & Assessment)
Time: 5–10 minutes
Summary:
• The teacher will ask the students to recall:
- Definition of science
- Differences between factual knowledge and scientific knowledge
- Key steps of the scientific method
Evaluation Method (Expanded):
• Exit slip/quiz: Students will write short answers to:
- Define science in your own words.
- Give one example each of a fact and scientific knowledge.
- List two steps of the scientific method.
Teacher will collect and quickly review for understanding
• Provide oral feedback before class ends
Assignment (Expanded): Follow-up Activity:
• Observe any simple natural phenomenon at home (e.g., growth of a plant) and write a short report using the scientific method.
Differentiation / Inclusive Strategies
• Struggling Learners: Provide simpler examples and one-on-one guidance during observation activity.
• Advanced Learners: Encourage designing a mini-experiment to share with the class.
• Students with Disabilities: Provide adapted materials, peer support, or verbal prompts.
Teacher’s Reflection (After Class)
