(Implementation of Curriculum 2013)

A. Identity

School Identity:  SMA N 1 DOLOK PANRIBUAN

Subject: Chemistry

Class / Semester: XII / 1

Basic Material: Chemical Elements

Time Allocation: 1 meetings (1 x 45 Minutes)

B. Core Competence

KI  1 : Living and practicing the religious teachings it embraces.
KI 2: Living and practicing honest, disciplined, responsible, caring (polite, cooperative, olerant, peaceful) behavior, courteous, responsive and proactive and showing attitude as part of the solution to problems in interacting effectively with the social environment and Nature and in placing ourselves as a reflection of the nation in the association of the world.
KI 3: Understand, apply, analyze and evaluate factual, conceptual, procedural, and metacognitive knowledge based on their curiosity about science, related causes of phenomena and events, and apply procedural knowledge to specific areas of study according to their talents and interests to solve problems .
KI 4: Cultivate, reason, present, and create in the realm of concrete and abstract realms related to the development of the self-study in schools and act effectively and creatively, and able to use methods according to scientific.

Indicators:1. Identify the existence of elements that exist in Indonesia, especially Indonesia.2. Identify products that contain these elements.Identify the physical properties of the main elements and transition elements (boiling point, melting point, hardness, color, solubility and specific properties of each element).3. Identify the chemical properties of the main elements and transition elements (reactivity to other elements).Indicators:

C. Learning Objectives1.By observing the demonstration or experiment activities, students can independently identify the abundance of elements in nature and the properties of the elements.
2. Given experimental data, students can independently make experimental reports about the physical properties and chemical properties of alkaline element elements, earth-algae, noble gases, halogens, third period elements and elements of the fourth period.
3. Through exercises and discussions, students can analyze the abundance of elements in Nature, especially in Indonesia, as well as the physical and chemical properties of alkaline element elements, earth-algae, noble gases, halogens, third period elements as well as elements of the fourth period.
4. Developing curiosity, thoroughness, diligence / tenacity, and mutual respect for opinions through group discussion, question and answer, and individual assignments.
5.Growing self-awareness of God's majesty and awareness of God's ordinance YME is the best determination for human life through demonstration activities, watching video or animation, and imaginative group / individual exercises.

·        
Observe  

Observe
the literature on the abundance of elements in nature, especially in Indonesia.

·        
Questioning
 

The
teacher asks the students questions, "What is the meaning of the element?
How is the abundance in nature? 

·        
Data
collection

T Teachers divide their students into groups to discuss the
abundance of elements / compounds in nature, especially in Indonesia. 

Teachers
provide some practice questions to be done by students through discussion 

·        
Associating

Recognize
the existence of order in the properties of the elements obtained thanks to the
creative discrateful for the abundance of elements in nature as a gift of God
YME.ommunicate Some students come forward to do the exercises on the board.

   Teachers
provide feedback and review on student work on the board.

      The
teacher discusses the exercises together with the students and answers the
students' questions.

H. Assessment (instrument attached)
1. Cognitive2. Presentations and discussions3. PsychomotorExercises :1. The flame test for Cl2 salt gives a green color. From the analysis data specify the name of Cl2's salt?2. The calcium metal can be prepared by electrolysis of fused calcium chloride with graphite electrode. Write down the reaction that occurred?3. How to separate Mg2 + and Ca 2+ ions from a solution containing Mg2 +, Ba2 + and Ca2 + ions?Procedure for flame retardation of alkaline earth elements1. Tools and materialsReaction glass test tubeWire nikrom burnerCrystal CaCl2 Crystal SrCl2Hydrochloric acid chloride BaCl22. Ways of working1. sample the sample crystals on the watch glass2. pour concentrated HCl solution in two test tubes3. Dip the nichrome wire on the HCl and heat it in a bunsen flame4. dip the nikrom wire back into the second reaction tube then into the next sample crystals heated over the flame bunsen and observe the flame color that occurs.               The experimental procedure of precipitation reaction of calcium, strontium, and barium compounds

I. Assessment of Learning Outcomes
1. Test the learning outcomes (mastery of the concept) using a chemical peskoran (each question is given a score of 1 if the answer is correct, and the score is zero if wrong).2. Assessment Attitude (behavior) using the rubric of behavior assessment3. Assessment of data processing skills of experimental results using performance rubric.
