Grade: 8 Subject: Science
Quarter/Semester: 4th Week No: 6 Day 2
I. OBECTIVES
The learners demonstrate an understanding of the species as
Content Standard being further classified into a hierarchical taxonomic system.
The learners should be able to report (e.g. , through a travelogue)
on the activities that communities engage in to protect and
Performance Standard
conserve endangered economically important species.
The learners should be able to classify organisms using the
Learning Competencies hierarchical taxonomic system. (S8LT-IV-20)
Knowledge Determine the categories of classifying organisms.
Skills Classify organisms using the hierarchical taxonomic system
Recognize the importance of classifying organisms using the
Attitude
hierarchical taxonomic system.

C. Activity
Based on the activity given, what do you think is our
topic for today?
What study that deals with the classification of living
things?
What do you call a person who systematically identifies,
classifies and organizes species based on similarities?
*Give a background of Carl Linnaeus, the Father of Modern Taxonomy
D. Analysis
Study the sample classification of organisms ( Table 1,
page 227, S8LM)
* Teacher facilitates and process the answers of students to the
following questions:
* Which organisms in Table 1 are similar up to the order
category?
* Which organisms are most closely related? Why do you say so?
* Can a dog and a wolf produce fertile offspring? Explain your
answer.
* Examine the row for species in Table 1. What have you
noticed?
* What does the first one refer to in the table? What about the
second

Name?
E. Abstraction
Introduce an activity to determine the scientific names of each
organism and classify each one based on the hierarchical taxonomic
system of classification. Visit this link

* Using the hierarchical taxonomic system of classification ( Kingdom,
Phylum, Class, Order, Family, Genus, Species) classify the following
organisms:
* 1. Cat
2. Dog
3. Philippine Eagle
4. Human
5. Milkfish (Bangus)
F. Application After the activity ask students the following questions:
1. Which organisms belong to the same order?
2. Which organisms are closely related? Explain.
3. Why are there more similarities between a cat and a dog
than between a dog and a human?
4. Which organism is different among the rest? Why?
G. Practical Applications of What do you think is the importance of classifying organisms
Concepts and Skills in using the hierarchical taxonomic system? Cite an example.
Daily Living
Why is there a need to classify organisms?
What will happen if organisms are not properly classified?
H. Generalization Is the process of classifying and or organizing applicable
to other things? Why?
