B. Basic Competence (KD) and Indicators:
KD of KI 1:
1.1 Recognizing the existence of regularity in the colligative nature of the solution, the redox reaction, the diversity of the elemental properties, the macromolecular compounds as the form of the greatness of God YME and the knowledge of the existence of such order as the result of the creative human thought that the truth is tentative.
1.2 Being grateful for the abundance of elements of the main groups and the transitional groups in the Indonesian realm as minerals is a gift of God YME used for the prosperity of the Indonesian people.

Indicators:
• Glorify the greatness of God Almighty
• Realize that the rules set by God Almighty are the best for us.
KD of KI 2:
2.1 Demonstrate scientific behavior (curiosity, discipline, honest, objective, open, able to distinguish facts and opinions, resilient, conscientious, responsible, critical, creative, innovative, democratic, communicative) in designing and experimenting and discussing embodied In everyday attitude.
2.2 Demonstrate co-operative, courteous, tolerant, peace-loving and caring environment and cost-effective in utilizing natural resources.
2.3 Demonstrate responsive and pro-active and prudent behavior as a form of problem-solving ability and decision making.

Indicators:
• Curiosity
• Honest in using experimental data (using the data as is and results according to experimental data)
• Thorough in processing and analyzing data
• Resilient in search of a source of knowledge that supports problem solving (can solve problems in a trace from beginning to end with the correct steps).
KD of KI 3:
3.1 Analyze abundance, trends in physical properties and chemical properties of major group elements (noble gases, halogens, alkalis and alkalis, period 3) and transition elements (period 4).

Indicators:
• Identify the presence of elements that exist in Indonesia, especially Indonesia.
• 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).
• Identify the chemical properties of key elements and transition elements (reactivity to other elements).

C. Learning Objectives
• By observing demonstration or experiment activities, students can independently identify the abundance of elements in nature and the properties of the elements.
• Provided experimental data, independently students can make experimental reports about the physical properties and chemical properties of alkaline element elements, earth-algae, noble gases, halogens, third period elements as well as elements of the fourth period.
• 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 elements of the alkaline, earth-algae, noble, halogen, third-period elements and fourth-period elements.
• Develop curiosity, thoroughness, perseverance, and mutual respect through group discussion, question and answer, and individual assignments.
• Growing self-awareness of God's majesty and awareness of God's ordinance YME is the best provision for human life through demonstration activities, watching video or animation, and imaginative group / individual exercises.

H. 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 assessment

3. Assessment of data processing skills of experimental results using performance rubric.

Behavioral Observations
