new lesson
How can the plant and insect survive in the covered jar?
In the environment, there are plants, animal and
microscopic organisms such as bacteria and fungi. A group of
organisms of the same kind living in the same place at the
same time is called population.
In the figure below, what populations of organisms do
you see?
B. Establishing a purpose for the Lesson
C. Activity: In a Relationship
1. Choose a study area in your school
2. Observe carefully the different organisms in your study area.
Caution: Do not catch the organisms. Just observe them.
3. Fill in the table below to show how organisms interact with
one another and the types of relationship they are engaged
in. Use the symbols below to identify the types of
relationship they have.
Interacting Organisms Symbiotic Relationship

Presenting examples / instances of the
new lesson
Symbols:
+ the organism is benefitting
- the organism is harmed
0 the organism is neither benefitting nor harmed by the
relationship
Symbiotic Relationships
+ + mutualism
+ - parasitism
+ 0 commensalism
D. 1. Which organisms are benefitting in the relationship?
2. Which organisms are harmed by other organism?
Discussing new concepts and practicing
new skills #1 3. How will you describe mutualism? Commensalism?
Parasitism?
E. Discussing new concepts and practicing
new skills #2
F. Developing mastery
(Leads to Formative Assessment 3)
G. Finding practical applications of concepts How can environmental pollution affect the relationship among
and skills in daily living organisms in the ecosystem?
H.
Making generalizations and abstractions What are the different relationships existing among
about the lesson organisms in an ecosystem?
I. Evaluating Learning Match the organisms in Column A to the symbiotic
relationships that they might have in an ecosystem in
Column B.
