Learning Competency and Objective
Apply ray diagramming techniques in describing the characteristics and positions of images
formed by mirrors and lenses.
Learning
Resources
Subtask: Construct ray diagrams to determine the location, orientation, size, and type
(L-O-S-T) of images formed by convex mirrors.
S10FE-IIg-51
ELICIT
Learners will be introduced to some terms/words. Then let them identify the types of mirrors
using some pictures.
ENGAGE
A picture will be shown to the learners.
Process question:
1. Have you seen your image on the two sides of clear spoon?
2. What do you notice about your image on each of the two sides of the spoon?
3. How will you compare your image from the two sides of the spoon?
EXPLORE
Activity 1.1: The Principal Rays (Source: Test Item Bank for Science 10)
Learners will identify the types of Principal rays.
Activity 1.2: Short Answer Test (Source: Test Item Bank for Science 10)
Learners will describe the steps in locating an image.
Activity 1.3: Are You L-O-S-T? (Source: Test Item Bank for Science 10)
Learners will identify the location of the object through ray diagramming.
EXPLAIN
Have the learners post their outputs on the board and have one member of each group to
present the output.
Key Questions:
1. How is a person’s image produced by a convex mirror?
2. What are the qualitative characteristics of images formed by convex mirrors?
ELABORATE
The class will be directed to read the Key Concepts.
Questions will be asked to deepen the discussion;
Why are some images formed by reflections better than the others?
How would you apply the ray diagramming method in describing the characteristics and
positions of images formed by convex mirrors?
