GRADE: 5th class

UNIT: What is on the Earth’s crust?

OBJECTIVE:

In Turkish form;

5.7.1.3. Fosillerin oluşumunu ve fosil çeşitlerini araştırır ve sunar.

5.7.1.4. Fosil biliminin, bir bilim dalı olduğunu kavrar ve bu alanda çalışan uzmanlara

In English form;

At the end of the lecture,

5.7.1.3. Students will be able to tell the kinds of fossils and how they come into

existence in nature clearly.

5.7.1.4. Students will be able to explain that paleontology is a kind of science and the

name of the experts working in this field correctly.

THEORITICAL FRAMEWORK:

In this plan, the universal step of instruction model which was designed by Robert

Gagne and Ausubel application is used.

For prerequisite knowledge, in the 3rd grade, students gained the information that there

are some water and land parts on the Earth’s surface. Also, there is an air layer which covers

all around the world. Actually, they know that the land layer includes some matters such as

stones, lands, rocks etc. Moreover, the teacher assumes that students learn the information in

which the land layer of the Earth’s crust is formed by some rocks.

1) Gain attention (5mn):

In the beginning of the lecture, the teacher shows a picture which is above and then

asks students a question that “Have you ever been to see any living dinosaur in your

environment?” Actually, the expected answer is “no”. However, if some students say “yes”,

the teacher can say that “Well, where did you see it?” Probably, students say that they can see

it at some museums. At this point, the teacher can indicate that the dinosaur students can see

at museum is not living now. Then, she says that “well, if we do not see any living of them,

how can we know that in some years dinosaurs had lived in somewhere?” “What do you think

about their ages?” The discussion part of the beginning goes with these questions. At the end,

the teacher says that “are you ready to meet with these guests who come from the past?” In

this way, the gaining attention part is ended.

2) State the outcomes of instruction (2mn):

In this part of the lecture, the teacher says that “today, we will find out more about

acquires knowledge about dinosaurs. In order to do that, we need to learn some special

terms like “fossil” and “its kinds”. You will also hear “paleontology” and

“paleontologist”. By the way, the teacher writes the key words on the board.

3) Stimulate recall of prior learning (8mn):

For recalling the prior knowledge, the teacher says that “to understand the new

concept, we should remember some definition and additional knowledge. Therefore, now, I

tell four small stories and you try to find the concepts”.

a) I am one of the layers of the Earth. I cover the surroundings of the Earth and I include

many kinds of gases such as oxygen, carbon dioxide etc. Who am I?

b) Again, I am one of the layers of the Earth. All livings are on me and I include some

stones, lands and rocks. I am thin in oceans where as thick on lands. Also, I am called

as Earth crust. Who am I?

c) I am one of the layers of the Earth. I include some water and fill in the blanks of the

Earth crust with this water. Actually, who am I?

A Atmosphere

B Lithosphere

C Hydrosphere

When students give the answer of each question, the teacher shows a picture as a hint.

4) Present stimulus material:

First of all, the teacher begins for this part of the lecture by showing two different

videos but, before she demonstrates them, s/he gives the worksheet with title “fossils and their

kinds”. Actually, the teacher wants to introduce the new words with the students. The filling

the blank process will be done during the lecture. Then, the first one is watched. In this video,

there are some explanations of some concepts. For example, what is fossil? What are the

kinds of fossil? How does the fossilization process occur? How do these fossils near the

Earth’s surface? After that, s/he gives the other worksheet before the second video is watched.

Then it begins and the answers of some questions like that “what is paleontology? What is

paleontologist? What should paleontologists know to be a paleontologist? What are their aims

in paleontology? Why is paleontology important for humanity?” are given clearly. Also, the

teacher writes all key words on the boards. From this point, s/he begins to tell the concept one

by one and in very organized way.

First of all, s/he indicates that while s/he is explaining the concepts, students should

take some notes in their worksheets. Then s/he begins with the meaning of fossil like that

“fossil is a kind of evidence which is found both between the layers of rocks and inside them.

It belongs to some livings such as animals, plants which lived in many years ago. Therefore,

we can say that fossils are impressions of living things and their activities. By utilizing them,

the scientists determine some livings which live in many years ago.”

Actually, s/he gives more explanations for the meaning of fossilization process. To be

more understandable, the teacher shows a picture about fossilization and also says that

“fossilization process is like that living organism dies and its outer part is eaten by some

organism. Then, its body’s or its mark’s inside or outer surface fills up with some sand, clay

or lime. Therefore, its parts are protected. After many years later, many rock layers occur and

this special formation is unable to retort. This is called as fossilization and with this process;

the living organism’s fossil can stay originally. Also, how many years ago an organism lived

on the Earth is determined by utilizing these layers. Actually, younger fossils are nearer to the

Earth’s surface than old ones. Furthermore, because of earthquakes or natural events, these

layers come out the Earth’s surface and so fossils can be noticed by people. After that, the

scientists take out them from land carefully.” In addition, s/he indicates that “fossilization is

generally seen in sea or lake because in land, died organisms decay mostly and so they cannot

have any chance to be a fossil. Also, we cannot say that all died organism can be a fossil

because some of them may decay.”

Then, s/he continues with explaining the kinds of fossils. Actually, the teacher uses a

small concept map with pictures which demonstrate the concept clearly and so students

can learn the information easily.

can be classified according to

such as such as

After, s/he indicates the other worksheet and wants students to fill in the blanks during

the explanations. Then, s/he says that “well, we continue with the understanding of what

paleontology and paleontologist are and why fossils are important. Firstly, paleontology is

discipline and it examines fossils in the world. People who study paleontology are called as

paleontologist. Actually, paleontologist should know chemistry, biology, geology and

astronomy. Their aims are describing different kinds of creature, creating a more complete

story of life on earth and developing new ideas about evolution.” Then, s/he can stress the

importance of paleontology because of its effectiveness on the history and also some clues

that arise from it about how human beings are changed over time in this planet.

5) Provide learner guidance:

For this part, there are two worksheets which uses during the explanations. Actually,

their functions are explained above.

6) Elicit performance:

At the end of these explanations, the teacher wants students to make a concept map

which summarizes all information that are talked in the lecture. To provide students guidance,

the teacher reminds students of information that are written on the board. Also, s/he indicates

that to make connections between the information is very important and to make these

connections with using minimum words is essential in concept map.

The main titles written on the board are paleontology, paleontologist, fossils, rock

layers, ancient animal, ancient plants, living things and their activities, the differences in sizes

and formations of fossils.

(Step 4, 5 and 6 go simultaneously and the time is 40mn approximately.)

7) Provide feedback (10 mn):

After the teacher guides students to prepare a concept map, s/he provides feedback

whether they use all the concepts with true lining words or not.

While they are making their concept maps, the teacher observes them whether they

form a proper one or not. If they form it properly, this indicates that they learn the subject

clearly. However, if they do not make the concept map because of a false information or lack

information, this shows that there is a misunderstanding about the concepts and so the teacher

explains the missing information. Then, s/he gives another chance to students to rewrite it.

After all students make their concept maps, the teacher shows the proper concept map which

is below.

8) Assess performance (10mn):

The teacher assesses students’ learning by giving a quiz in which there are some

main questions about the subject. After students answer the questions, s/he evaluates their

performance according to the number of true questions.

Number of true questions Result

5 or 6 Excellent

3 or 4 Adequate

1 or 2 Inadequate

9) Enhance retention and transfer (5mn):

The summary of the important factors such as the meaning of fossil and fossilization

process, paleontology and paleontologist, the importance of information gained by fossils are

emphasized. This summary part is made by showing an animation in which there is “kel

oğlan” and he is stuck in a room. To get him off, students should give the right answers of the

questions that are relevant to the concepts. After that, the teacher shows a video in which a

dinosaur which lived before 75 million years ago is founded by some paleontologist. This

video is wanted to be watched because there should be an accommodation between the

beginning and the last part of the lecture. Also, the enhancing process is wanted to be

amazing. After that, the lecture is ended.
