TITLE: Binomial System of Classification click here

OBJECTIVES:

• Explain how and why biologists classify organisms
• Describe the background of the modern classification

CONTENTS

• The Systems of classification
Taxonomy and Evolution

MATERIALS:

• Reference Books / Text books
• Pictures of animals and plants; or better yet,
go to a nearby garden.
• Laptop
• Internet

STRATEGIES (4 A's)

Motivation

- Make a chart showing the relationship between the members in your family.What did you do to indicate how the members in your family are related to one another? (While all members of the family are related,each has a distinct role and maybe classified as father, mother, uncle, brother, sister and so on)

1. ACTIVITY:

Let the students discuss the six kingdom classification of living things.
Let them explain to the class why there is a three domain of life
scheme, and a six kingdom classifications. Gauge how much students
know about the six kingdoms by asking the following questions:

• What are some differences and similarities in plants and animal cells? click here
• Do some living things that exist today have already existed millions
of years ago?
• Are the living things that exist today the same as they were millions
of years ago?

2.ANALYSIS:

Ask: Is there any link between the humans and the octopuses? Do they
come from same ancestor? How about humans and polar bears?
(Octopuses and humans came from the same ancestor 600 million years
ago, and polar bears and humans about 100 million of years ago)

3. ABSTRACTION:

• Appreciating the existence of diverse forms of classification
• Understanding the importance of evolution in classifying living things
• Manifesting system and orderliness in all tasks

4. APPLICATION

Essay/quiz

1. Summarize the major characteristics of the three domains of life.
2. Conduct a research on strains of bacteria.
3. Give possible reasons why scientists sometimes do not agree on
a single idea.
4. Ask the students to Perform Activity 7 Protists parade on pages 29-32 of
lab manual

ecology


Ecology (from Greek oîkos, "house"; -λογία, -logos, study of) is the interdisciplinary scientific study of the distribution and abundance of organisms and their interactions with their environment.


photosynthesis


Photosynthesis-is the process of converting light energy to chemical energy and storing it in the bonds of sugar. This process occurs in plants and some algae (Kingdom Protista). Plants need only light energy, CO2, and H2O to make sugar. The process of photosynthesis takes place in the choloroplast specifically usingchlorophyl the green pigment involved in photosynthesis.
