Learning Earth and Life

Activity/Strategy
I. OBJECTIVES
A. Content Standards The learner demonstrates an understanding of:
1. History of life on Earth.
B. Performance Standards The learner shall be able to:
Create a representation of the history of life on Earth and the sequence
of the geologic time scale.
C. Learning Competencies/ At the end of the session, at least 85% of the learner should be able to:
Specific Objectives 1. Understand and analyze the origin of life that exist on Earth.
2. Appreciate the actuality of other organisms that existed on Earth.
3. Create a timeline that shows the sequence of the geologic time scale
II. CONTENT
A. Topic Evolution and Origin of Biodiversity
III. LEARNING RESOURCES
1. Curriculum Guide pages Page 2 STEM_BIO11/12
2. Textbook page
3. Additional Resources www.youtube.com , www.itutor.com , www.asapscience.com
4. Other Learning Resources

A. Materials
1. For Teacher Curriculum Guide, and Laptop
2. For Students Science Notebook
IV. PROCEDURES
A. Reviewing previous lesson or What is pedigree analysis?
presenting new lesson What is the importance of Pedigree analysis?
B. Establishing the purpose for “CLASH OF CLANS”
the lesson The class will be group into four. All they need to do is to answer the
questions that is related to the topic in a span of 2 minutes. One
representative per question but the groupmates can help the member for as
long as he/she will be the one to voice out the answer. Every correct answer
corresponds to one point. The group that will gain the greatest number of
points will be the winner.
C. Presenting examples/ Students are shown pictures as the example of the organisms that existed on
instances of the new lesson Earth.
D. Discussing new concepts and In a span of 3 minutes explain the quotation
practicing new skill #1 “By 3.8 billion years ago, Earth contained all the ingredients necessary for the
earliest forms of life to evolve.”
“SHOW TIME”
The class will be shown a video that will help them better understand the
history of life on Earth.
E. Discussing new concepts and “BIG 5”
practicing new skill #2 Each group will receive an envelope containing a manila paper, marker and
paper strips. On the counterpart you need to solve a jigsaw puzzle to find out
the data connected to the history of life that existed on Earth. The activity
must be done within 2 minutes.
Note: The back part of the puzzle contains the information you needed.
F. Developing Mastery (Leads to What are the gases the are present in the early earth atmosphere?
formative assessment 3) Describe the chemical condition of the early Earth.
Give some examples of organisms that existed on Earth.
What are the big five massive extinction?
G. Finding practical applications “TRAVEL LOKA”
of concepts and skills in daily With regards to the Earth life history, where do you see yourself 5-10 years
living from now?
If you were to travel back in time when Pangea existed, where would you
like to go?
H. Making generalizations and What have you learned?
abstractions about the lesson Early in Earth's history, both volcanism and impact cratering were very
common processes. So, both may have provided the environments needed
to transform disparate chemical compounds into living organisms and may
have provided a suitable habitat for that life to evolve.
 I. Evaluating learning True or False

1. Ordovician period ended due to an ice age, and gamma ray burst.
2. Devonian period is also known as the age of the fishes.
3. Permian and Paleozoic period has the largest mass extinction on
record.
4. Scientist call the seven continents Pangea.
5. Fossils are used to find evidence of organisms existence.
1. Additional activities for Research about the following:
application or remediation a) Artificial selection
b) Natural selection
c) Genetic drift mutation and
d) Recombination
V. REMARKS
VI. REFLECTIONS
A. No. of learners who earned
80% on the formative
assessment
B. No. of learners who require
additional activities for
remediation
C. Did the remedial lesson work?
No. of learners who have
caught up with the lesson
D. No. of learners who continue
to require remediation
E. Which of my teaching
strategies worked well? Why
did this work?
F. What difficulties did I
encounter which my principal
and supervisor can help me
solve?
G. What innovation or localized
material did I use/ discover
which I wish to share with
other teachers?
