School: SMA NEGERI I PANGURURAN

Subject: CHEMICAL / CHEMICAL TRADE

Class / Semester: XI / 1

Time Allocation: 3 X 45 MINS (1 X MEETING)

A. Core Competence (KI)

KI3:

Understanding, applying, analyzing factual, conceptual, procedural knowledge based on curiosity about science, technology, art, culture, and humanities with the insight of humanity, nationality, state and civilization related causes of phenomena and events, and applying procedural knowledge to the field of study Which is specific to his or her talents and interests to solve problems.

KI4:

Processing, reasoning and chanting in the realm of concrete and abstract realms are linked to the development of the self-study in schools independently, and capable of using methods according to scientific rules.

Indicates the characteristics of ionic compounds or covalent compounds based on the nature of polarity through experiments

C. Learning Materials

• Metallic bonding

Factual

Displays a picture of the forged iron, the iron being used.

Conceptual

In iron there is a metal bond that has a strong bond.

        Metal valence electrons are not tightly bound (because of their low ionization energy), so they are relatively free to move.

    It is understandable why the metal is a good conductor of heat and electricity, and also shiny.

Procedural

It proves significantly through heating the metal with a candle

Metacognitive

Grouped several examples found everyday that belong to metal bonds based on the properties of the metal.

D. Learning Activities

Third Meeting: (3 x 45 minutes)

Indicator: Explains the metal bond

a. Activity Introduction

• The teacher greets the students with a friendly smile / communicative

• Teachers invite students to pray together according to their beliefs

• Teacher checks student attendance

• Teachers convey the learning materials and learning objectives that students must achieve in this lesson

• Teacher asks about valence electron and lewis structure of metal elements

b. Core Activities

No.	Sintaks Discovery	Learning Activities
1.	Stimulus	• Teacher is singing a forged iron photo / video. • Learners listen to the given impressions.
2.	Problem Statetment	• Teachers divide students into groups. • Teachers give students tasks in groups to discuss questions / problems based on the images presented, eg why iron can be forged. • Each group discusses a given task, to formulate a question of question: why metal compounds can be forged / why iron can heat
3.	Data Collecting	• Each group collects data to answer questions raised through literature studies
4.	Data Processing	• Students discuss the findings in each group.
5.	Verification	• One group presented the results of the discussion to equalize perceptions. • Teachers reinforce and / or straighten out group outcomes. • Teachers provide practice questions about metal bonds and their properties. • Teachers collect student answers to be assessed and announced at the next meeting
6.	Generalization	• Students conclude learning outcomes about metal bonds and their properties, teachers reinforce and straighten out common conclusions

c. Closing Activity

• Students and teachers review the learning activities of metal bonding.

• Teachers inform students to prepare lessons for future meetings.

E. Assessment Technique

Write down and explain the four properties of the metal bond and give the sample a maximum of 2!

 Valent electrons of metal are not tightly bonded (due to their low ionization energy), so they are relatively free to move.

 It is understandable why the metal is a good conductor of heat and electricity, and also shiny.

 Metals can be compressed and stretched without being broken, because the atoms shifted in the crystal structure will remain in the same position. This is because the mobility of the ocean of electrons between positive ions is a buffer

This state is different from the ionic crystals.

 When this ionic crystal is pressed, it will crack or break. This is due to the shift of positive and negative ions in such a way

So that positive ions are adjacent to positive ions and negative ions with negative ions, such a condition leads to repulsions so that the ionic crystals.

EXAMPLE: IRON, COPPER

F. Media / tools, Materials, and Learning Resources

1. Media: presentation slides

2. Learning Resources: chemistry class X book, internet

Squatters:

1. In the introduction it is even better if the 3-dimensional example is shown directly: if it is difficult to be given directly it can be represented with the image, not yet found the latest video possibly could be hampered from apps owned by the renderer computer

2. Sentences on metacognitive should be able to describe the views of students into the future, for example: students predict future metals can be utilized for a variety of things better

3. Techniques assessment ,,, on the form of the instrument in writekan attachment

4. The core activity is good ,, can describe the learning activities
