1. ANALYTIC RUBRICS
Topic: BIOTIC AND ABIOTIC COMPONENTS OF ECOSYSTEM
Objective:
To enable the students distinguish biotic and abiotic components of an ecosystem.
Specific:
Identify 5-10 examples of biotic and abiotic components.
Give five to ten defining characteristics of biotic component.
Give five to ten characteristics of abiotic component that makes it different from biotic
component.
Determine three to five relationship or interactions of biotic and abiotic components.
Explain how these interactions help in maintaining the balance of ecosystem.
Task Design:
1. Bring the students to the school ground.
2. Ask them to identify examples of biotic, as well as abiotic component, they can find in the school
ground.
3. Let the student list their bases on identifying the examples as biotic or abiotic component.
4. Ask the students to identify three to five interactions involving biotic and abiotic components.
5. Let the students explain how these interactions help in balancing our ecosystem.
Scoring Rubrics:
CRITERIA
BEGINNER (1)
DEVELOPING (2)
EXEMPLARY (3)
CATEGARIZATION of
the components of
ecosystem
Identified only 1-3
examples of biotic and
abiotic components
Identified 4-7 examples
of biotic and abiotic
components
Identified 8-10 examples
of the biotic and abiotic
components
CONCEPT
Gave 1-3 defining
characteristics of biotic
and abiotic components
Gave 4-7 defining
characteristics of biotic
and abiotic components
Gave 8-10 defining
characteristics of biotic
and abiotic components
IDENTIFICATION OF
INTERDEPENDENCE
Listed less than three
interactions involving
both components of
ecosystem
Listed three to four
interactions involving
biotic and abiotic
components
Listed five ecological
interactions involving the
two components
APPLICATION
Superficial explanation
of how these interactions
maintain the ecosystem’s
balance and fewer
examples were cited
More elaborate
explanation of the
interactions and more
examples of the
interactions were given
In depth explanation of
the application of the
interactions in attaining
ecosystem’s balance
(determining differences
between biotic and
abiotic components)
