Inquiry Based Lesson Plan

2. Class: IX Date: 8th July 2020 (3rd Period)
10th July 2020 (5th period)
Subject: Physics Topic: Refraction of light
Overall Objectives: At the end of the lesson a student should be able to
1. Define refraction of light.
2. Describe refraction through a glass slab.
3. Design and carryout an experiment on refraction.

3. •Can not learn every thing in the class from their
teachers.
•Find out about the real world through authentic
engagement.
•Create ways to seek answer through communication

Lesson Introduction-Phase I (5 min)
Light travels in a straight line. This property of light is true as
long as the light continues to travel in the same medium

The phenomenon of bending of light ray when it passes
from one medium to another medium of different
densities is called refraction of light.
Original path
Bending of light ray

7. 1. What are the different cases of refraction?
2. What happens to the light when it is incident normally on the
surface of the glass slab?
3. What happens when light travels from optically denser medium
to optically rarer medium and
4. What happens when the light travels from optically rarer medium
to optically denser medium?
ASK from the statement of refraction (team work)-15 min
Different cases of refraction and investigation method? (discuss)
Divide into 5 groups

8. Investigate: come up with possible solutions (15 min)
Problems Possible expected solutions
Incident ray falling normally on the
surface of the glass slab
The light travels in a straight line
without any refraction.
Light travels from optically denser
medium to optically rarer medium
Refracted ray bends away from the
normal
Light travels from optically rarer
medium to optically denser medium
Refracted ray bends towards the
normal.
Compare incident angle and the
refracted angle (through experiment)
Other physics teachers, library, IT lab with wi-fi

9. Closure (5 mins)
•Ask: Students ask questions about the different cases of
refraction.
•Investigate – come up with possible solution or hypothesis
•ELA: refining problems and solutions (20 mins)

10. PHASE 2

11. Lesson Introduction (hypothesis sharing and confirmation for testing)
Problems Possible expected solutions
What happens to the light when it is incident
normally on the surface of the glass slab?
The light travels in a straight line with any
refraction when it is incident normally on the
slab.
What happens when light travels from
optically denser medium to optically rarer
medium?
When light travels from optically denser
medium to optically rarer medium, it bends
away from the normal
What happens when the light travels from
optically rarer medium to optically denser
medium?
When the light travels from optically rarer
medium to optically denser medium, it bends
towards the normal.
