Lesson plan
Lesson 2: adaptation
and diversity of living organisms
Background
Introduction to diversity of
animals when you visit the zoo
You may see the animals and
you observe the varity among these animals in a lot of different
characteristics such as the shape and the way of feeding
Living organisms depended on each other in the
environment where they live in.
Evolution of Life
The diversity of life on Earth today is
the result of evolution. Life began on Earth at least 4 billion years ago, and
it has been evolving ever since. At first, all living things on Earth were
simple, single-celled organisms. Much later, the first multicellular organisms
evolved, and after that, Earth’s biodiversity greatly increased.
Today, scientists accept the evolution
of life on Earth as a fact. There is too much evidence supporting evolution to
doubt it. However, that wasn’t always the case.
Lesson objectives
At the end of the lesson ,
students should be able to
1-
Student should be able to identify the adaptation cocept
2- The sudent should be able to countable
the reasons of diversity of living organisms
3- Students show the difference between
camel's limbs and horse's limbs
4- The sudent should be able to explain
the task of camel pad ends in a thick flat one
5- the student should be able to observe
realationship between adaptation and motion in mammels
6- Student
identifies about Structural(anatomical) adaptation
7-
Student explains what does it
meant by behavioural adaptation
8- Student deduces the importance of some shapes
of modification of living organisms
9- The student discusses relationship
between the adaptation and motion in mammals
10- The student predict some shapes of modification
of living organism
11- Student
estimates the greatness of Allah in the variation of creatures
Students' prior
knowledge :
Before the lesson
students should able to:
1- Explain what is
meant by Extintion
Some living organisms couldn't adapt to the environmental changes so
they pershid.
Ex : Dinosaurs – Mammoth
2- Students count
some forms of adaptation of living organisms
such as birds migration ,hiding in the winter for some animals .
Concepts:
1- Adaptation: It is a modification of aliving organism's
behaviour , body structure or organs biological functions to become more
adapted to
the
environmental conditions where it lives in.
2- Structural
adaptation
3- Functional
adaptation
Learning resources
some photos
for different kinds of animals and living
organisms
Display the
video that indicate the adaptation and the
motion in
mammel's
content:
|
Camel pad ends in athick flat one .Horse hoof
ends in astrong solid
|
|
Camel’s
limbs
Camel pad ends in thick flat one to enable the camel
wandering through the hot
|
|
Horse's
limbs :
Horse hoof ends
in astrong solid end
To help the horse go through the rocky soil
|
|
Mammal's limb's are modified in many shapes and
forms to suit the required ways of movement such as : Walking , flying ,
swimming ,
|
|
it is an adaptation that
studies the structure of one body organ ex: the horses 's hoof structure the
camel's pad structure
|
|
it is adaptation in the
activity of some animals in different times of the daylight ex: birds migration at certain times of the
year Activity of birds during the daylight and bats at night
|
|
Bats the two
forelimbs are modified into two
wings-like structure
|
|
The way of
movement for
Whales(Swimming
and diving), Bats are flying and Horse running on the rocky soil
|
|
Whales, Dolphins,
sea lion
the two forelimbs are
modified to become paddles (fin-like structure
|

induction :
The lesson
begins with worksheet distributed to each pair of students which looks like aquiz
1- How many cycles
of the backbone of the snake?

of some animals which active in daytime?
…………………………………………………...
4- Record the names
of some animals which active in the night?
Assessments

the causes of adaptation in animals :
…………………………………………………………………………………..
…………………………………………………………………………………..
