I.OBJECTIVES
A. Content Standards: The learners demonstrate an understanding of the images formed by
the different types of mirrors and lenses.
B. Performance Standard: The learners shall be able to construct a simple optical project
using lens and mirror
C. Learning Competency: Predict the qualitative characteristics (orientation, type, and
magnification) of images formed by plane and curved mirrors and lenses. S10-FE-IIg-50
Learning Outcomes:
1. Determine the height, width & the distance from the mirror of the image formed by plane mirrors.
2. Compare the actual width, height and the distance from the mirror of the object with that of the
image formed of the plane mirror.
3. Cooperate actively in the laboratory activity.

Activity 1
GROUP 1
Mirror, mirror, on the wall…
Objectives:
• Determine the height, width, and the distance from the mirror of
the image formed by plane mirrors.
• Compare the actual height, width and the distance from the mirror of the object
with that of the image formed by plane mirror.
Materials:
• 1 (10 cm x 15 cm) plane mirror
• 1 graphing paper
• 10 one–peso coins
• modeling clay
• pen
Procedure:
1. Let the mirror stand vertically along a line on a graphing paper as shown in Figure 1. Use the
modeling clay to support the plane mirror.

2. Using a pen, make three (3) different marks along the intersections on the graphing paper in front
of a mirror.
3. Measure the distance of each mark from the mirror by counting the number of parallel lines
between the mark and the base of the plane mirror. Record your data in a table similar to Table 1
below.
4. Look at the images of the marks formed by the mirror. Measure the distance of each image from
the mirror by counting the number of parallel lines between the image and the base of the mirror.
Record this also in Table 1.
Table 1. Distance of the Object and Image from the Mirror

Q1. Refer to Table 1, compare the distance (number of parallel lines) from the mirror of the object
with that of the image.
5. Stack 10 pieces of one-peso coin in front of the plane mirror as in Figure 2. Using a ruler, measure
the height and width of the stack of coins. Measure also the height and width of the image as seen
on the mirror. Enter your
measurements in a table similar to Table 2.

Table 2. Height and Width of Object and Image
Q2. How do the height and width of the object compare with the height and width of the image
GROUP 2
ACTIVITY 2: Watch and Learn
Image Formed in a Plane Mirror- ( video clip)
1. Based from the video, compare the distance from the mirror of the object with that of the
image.
2. How do the height and width of the object compare with the height and width of the image?

ACTIVITY 3: BOOK WORM
Read the article
Imagine a world without mirrors. The way we conduct our lives would be very different.
Would we have different views on the way we look? How would we know what was behind us
while driving? Studies suggest that people who are very concerned with their appearance look at
their reflection in a mirror 20 or more times a day. There's certainly nothing wrong with this; some
people just want to look nice. It's interesting to think, though, about how different our lives would
be without mirrors.
Even from a strictly scientific standpoint, mirrors are found in countless high-tech devices.
From microscopes to telescopes, cameras to projectors, mirrors play an important role in how
humans interact with the world around them. This important role would not be possible if weren't
for the simplest type of mirror: the plane mirror.
A plane mirror is any mirror with a flat reflective surface. Plane mirrors reflect light at the
same angle it hits the mirror, so there is very little distortion of the image, if any. The type of
mirror that's hanging in your bathroom is a plane mirror.
The illustrations below describe the size and the distance of the image formed in a plane
mirror.

1. Based from the article and illustrations, compare the distance from the mirror of the
object with that of the image?
2. How do the height and width of the object compare with the height and width of the
image?
ACTIVITY 4: Hi-Tech
The students will use phet simulations for plane mirror.

1. Based from the simulations, compare the distance from the mirror of the object with that of
the image?
2. How do the height and width of the object compare with the height and width of the image?
