1) The lesson discusses the relationship between the number of images formed and the angle between two mirrors. Specifically, it describes how as the angle increases, the number of images decreases, with the number being inversely proportional to the angle.
2) The students will perform activities to observe image formation using mirrors and determine the number of images at different angles. They will use the formula N=360/θ-1 to calculate the number, where N is the number of images and θ is the angle in degrees.
3) At the end, the students will answer questions to assess their understanding of the key concepts about the relationship between angle, number of images, and the formula used.

School Sta. Cruz High School Grade Level 10 Daily Lesson Teacher DAISEREE DR. SALVADOR Learning Area SCIENCE Log Teaching Dates and Time Oct. 29, 2018/ 8:20am-9:20am Quarter 2nd Quarter Santa Cruz, Santa Maria, Bulacan I. OBJECTIVES The learners demonstrate an understanding of the images formed by the A. Content Standards different types of mirrors and lenses. B. Performance Standards C. Learning Describe the images formed by curved mirrors by applying the mirror Competencies/Objectives equation S10FE-IIg-50.
II. CONTENT Relationship between the Number of Images Formed and
Angle between the Two Mirrors III. LEARNING RESOURCES A. References 1. Teacher’s Guide Pages Pages 140-141
2. Learner’s Materials pages Pages 178-180
3. Text book pages 4. Additional Materials from Two plane mirror, paper protractor, one peso coin Learning Resources B. Other Learning Resources IV. PROCEDURES A. Reviewing previous lesson Call the students to write their answers for the following questions. Then or presenting the new lesson have the class agree with their answer using their thumb (thumbs up = agree, thumbs down= disagree, thumbs sideward= undecided). 1. Maya is 1 m away from the mirror, her image will be ____ m away from the mirror. 2. The height and the width of a chair is____ the height and the width of its image in the plane mirror. 3. The angle of incidence is ____ the angle of reflection. 4. The word”bed” would appear as _____ in a plane mirror. B. Establishing a purpose for Let the class play the famous reality gameshow “Who wants to be a the lesson Millionaire.” The teacher asks the students who wants to be a millionaire. Those who want to be a millionaire would have to tiptoe and stretch their hands towards the ceiling. After the stretching, tell the students that today’s activity could be their key to become a millionaire. C. Presenting The teacher divides the class into 8 groups. The teacher checks the materials Examples/instances of new and presents the objectives and procedure of the activity. lesson D. Discussing new concepts Let the students perform activity 4 entitles “Who wants to be a and practicing new skills #1 Millionaire?” After performing the activity, let the representative from each group present their output. E. Discussing new concepts The teacher discusses how to determine the number of images formed by and practicing new skills #2 two mirrors using formula. Formula: N= 360/θ-1 Where in: N= no. of images formed by two mirrors θ = angle between the mirror F. Developing mastery Let the students answer the question. (Leads to Formative Assessment) 1. What happens to the number of images formed as you vary the angle between the mirrors? 2. What relationship exists between the number of images formed and the angle between two mirrors? G. Finding Practical Let the students answer the question. applications of concepts and 1.How should the mirrors be arranged such that an infinite number of skills images will be formed or seen? H. Making generalizations and The teacher re-discusses the relationship between the number of images abstractions about the lesson formed and angle between the two mirrors. Multiple images are formed by the reflection that happens when arranging at least two mirrors. As the angle between the mirrors increases, the number of images formed decreases. The number of images is inversely proportional to the angle between two mirrors. The formula in the determining the number of images formed by two mirrors is N= 360/θ-1. I. Evaluating Learning The teacher tells the students different statements about the relationship between the number of images formed and angle between the two mirrors, let them tell if the statement is TRUE or FALSE. 1. Multiple images are formed by the reflection that happens when arranging at least two mirrors. 2. As the angle between the mirrors increases, the number of images formed decreases. 3. The number of images is inversely proportional to the angle between two mirrors. 4. Arranging the mirrors in The formula in the determining the number of images formed by two mirrors is N= 360/θ-1. J. Additional activities for Compute for the number of images formed by two mirrors placed at the application or remediation following angle. 1. 20° 2. 40° 3. 10° 4. 15° 5. 24° V. REMARKS VI. REFLECTION (Note: The # of learner’s should be stated by section) A. No. of learners who earned 80% on the formative assessment B. No. of Learners who require additional activities for remediation C. Did the remedial lessons work? No. of learners who have caught up with the lesson. D. No. of learners who continue to require remediation E. Which of my teaching strategies worked well? Why did these work? F. What difficulties did I encounter which my principal or supervisor can help me solve? G. What innovation or localized materials did I use/discover which I wish to share with other teachers?
