Reference Materials

The following resources were used in planning this lesson:

• 9 – Years Basic Education Curriculum.
• Abuja educational Resource Center Scheme of Work.
• NAPPS National Unified Scheme of Work.
• Online data from: Britannica – Friction | Definition, Types, & Formula
• Relevant textbooks.

Instructional Materials

To deliver this lesson, the teacher will employ the help of the following materials:

• Sandpaper.
• Grinding stones.
• Matchbox cars.
• Rubber shoes.
• Chart showing different effects of friction.

Rationale for the Lesson

Understanding the meaning and effects of friction helps pupils recognize its relevance in daily activities, such as walking, driving, or writing, and how it contributes to safety and efficiency.

Prerequisite/Previous Knowledge

Pupils have learned about the effects of force and can relate it to their experiences, such as pushing or pulling objects.

Lesson Content

Meaning and Effects of Friction

Friction is the force that opposes the motion of one surface sliding or rolling over another. This means that friction slows down or stops moving objects.

Effects of Friction:

The following are examples of the effects of friction:

1. Slows down motion: Friction between car brakes and wheels helps slow the car down. friction between a book and a table slows down the book when pushed.
2. Produces heat: Rubbing hands together generates warmth due to friction. Sharpening a knife on a stone produces heat.
3. Wears surfaces: Constant friction on shoe soles makes them wear out. Car tires wear out due to friction with the road.
4. Enables grip: Friction allows us to hold objects securely, like a pen while writing. it also helps tires grip the road.
5. Affects efficiency: Machines may require oiling to reduce friction and work more smoothly. Bicycle chains need lubrication to reduce friction.

Teaching Methods

To deliver this lesson,‌ ⁤the teacher will⁤ adopt⁤ the following methods: Description,Presentation,Group Work,Discussion,Interactive.

Instructional Procedures

To deliver this lesson, the teacher will adopt the following steps:

Step 1: Introduction

Pupils’ Activity: Pupils observe and listen attentively.

Step 3: Examples of Friction

Time: 10 mins
Teaching Skill: Interactive
Teacher’s Activity: The teacher guides pupils to demonstrate effects of friction using items like rubber shoes or sandpaper.
Pupils’ Activity: Pupils participate actively in group activities.

Step 4: Note-Taking

time: 5 mins
Teaching Skill: Guided Writing
Teacher’s Activity: The teacher writes key points on the board for pupils to copy into their notebooks.
Pupils’ Activity: Pupils copy notes into their books.

Step 5: Evaluation/Review

Time: 5 mins
Teaching Skill: Oral Questions
Teacher’s Activity: The teacher asks questions to assess pupils’ understanding of friction and its effects.Pupils’ Activity: Pupils answer questions orally.

Objective-aligned checks:

1. Define friction and list five effects of friction.
2. Demonstrate the effects of friction using practical examples such as grinding stones or walking.

Step 6: Conclusion

Time: 5 mins
Teaching Skill: Recap
Teacher’s Activity: The teacher summarizes the lesson and links it to real-life applications.
Pupils’ Activity: Pupils share what they learned in class.

Lesson Keywords

• Friction – A force that opposes motion between surfaces in contact.
• Motion – The act or process of moving or being moved.
• Heat – A form of energy associated with the movement of atoms and molecules.
• Grip – The act of holding something firmly.
• Efficiency – The ability to avoid wasting materials, energy, efforts, money, and time in doing something or in producing a desired result.

Lesson Evaluation

To evaluate the learning, the teacher asks pupils to:

1. Define friction.
2. List three effects of friction.
3. Give two examples of activities where friction is helpful.
4. Demonstrate one effect of friction using provided materials.

Assignment/Homework

1. Explain how friction helps in walking.
2. List five activities where friction is critically important.
3. Describe a situation where reducing friction is necessary.

Differentiation

• For slower learners: Provide simplified explanations and hands-on demonstrations with more guidance.
• For advanced learners: Challenge them to research different types of friction and their applications.
• For visual/auditory/kinesthetic learners: Use visual aids, verbal explanations, and practical activities to cater to their learning styles.

Note for Teachers

Encourage active participation by using real-life examples pupils can relate to, such as walking or cycling. Always ensure safety during demonstrations. Happy teaching!
