Science 5 Quarter 3 Week 2 MATATAG Curriculum / Revised K-12 LE Based PowerPoint Presentation

Science 5 Quarter 3 Week 2 MATATAG Curriculum Lesson Exemplar Based PowerPoint Presentation For other subjects:    • Grade 5 Quarter 3 Week 2 MATATAG Curriculum   LEARNING COMPETENCIES The learners plan and carry out a scientific investigation to determine the effect of different surfaces on the size of frictional forces. The learners will be able to: Lesson Objective 1: describe friction. Lesson Objective 2: identify the types of friction. Lesson Objective 3: identify the factors that affect friction. Lesson Objective 4: investigate the effect of different surfaces on the magnitude of frictional forces. Learning Competency 2: The learners demonstrate how friction can produce heat and investigate ways of reducing and increasing friction. The learners will be able to: Lesson Objective 1: cite ways of reducing and increasing friction in everyday scenarios. Lesson Objective 2: demonstrate how friction can produce heat. Lesson Objective 3: discuss the advantages and disadvantages of friction. CONTENT Friction Force ● Types of Friction Force The four types of friction are static, sliding, rolling, and fluid friction. ● Factors affecting Friction The factors that affect the amount of friction between two rubbing surfaces are surface texture, normal force, and surface area. The surface texture of objects affects the magnitude of frictional forces. Increased surface roughness enhances friction by promoting interlocking. ● Effects of Friction A. Advantages of Friction 1. It slows down a moving object and causes it to stop. 2. It produces heat to give warmth. 3. It allows grip and prevents slipping. 4. It provides traction. B. Disadvantages of friction 1. It causes overheating. 2. It causes wear and tear. 3. It increases energy consumption. Friction converts mechanical energy into thermal energy, generating heat. ● Reducing and Increasing Friction Increasing Friction ● Using rubber materials ● Using rough surfaces or increasing the roughness of the surface ● Increasing the weight of an object Reducing Friction ● Using ball bearings, rollers, and wheels ● Applying lubricants, oil, grease or wax ● Smoothing or polishing the surface in contact ● Making an object aerodynamic or streamlining the shape of the body Lubricants reduce friction by decreasing the surface’s roughness. Principles apply in machinery operation, sports equipment design, and material handling. Controlling frictional forces and managing heat is crucial for performance optimization, efficiency, and safety. Follow me on Tiktok: https://www.tiktok.com/@matatagpowerp... Thank you!
