F. Learning Approach and Model

1. Approach: Contextual

2. Model: Guided inquiry learning

G. Steps of learning activities

a. Introduction (15 minutes)

Phase 1 : Presenting Activities

1. Teacher enters the class and greets the students with “Assalamualaikum Students!”

2. Teacher creates a religious classroom atmosphere by appointing in the class leader to lead the prayer

3. Teacher checks student attendance(teacher still discipline attitude),cleanliness and class neatness as a form of environmental awareness

4. After preparing the lesson,the teacher conveys a preception to the students with the aim of guilding the students memory on the materials to be given at this meeting by asking “what is solution and solute?”

5. Students are asked to answer the question and the teacher completes the student’s answer

6. Teacher motivate students to attract students attention with describe the process of cooking water in daily life then ask, “when is the water boiling?”

7. Students are asked to answer and then completed by the teacher

8. Teacher divide students into group with heterogeneous members

b. Core Activity (60 minutes)

1. Teacher distributes LKS to each group and presents the problem: “at what temperature in the following solution boiling and which in the first boiling?”

a. 10 mL of aquades

b. 10 mL of 0,5 M NaCl solution

c. 10 mL of 1 M NaCl solution

Phase 2 Creating Hypotheses

2. Teacher provide opportunities for students to discuss each other to make hypothesis and write it to LKS.

Phase 3 Designing Experiments

3. Teacher give students the opportunity to develop experimental steps in the group discussion within a few minutes guide students to develop the correct procedure right on the board.

Phase 4 Experiment

4. Teacher guide students to experiment to test hypothesis that have been students were made with experiments of boiling point in some olutions that has been provided.

5. Student make observations and record carefully and then throughly the results of their experimental oservations on the LKS.

Phase 5 : Collecting and Analyzing Data

6. Students analyze experiment data, make a discussion of the results that they get by comparing the existing literature to prove thecorrectness of the hypothesis they make,and answer the questions in the LKS.

7. the teacher gives each group a chance by pointing to one members of his group todeliver the results of data processing collected at the front of the class and other groups give attention and respond for his friend’s presentation, then the teacher gives the reinforcement for the results of student’s discussion to make students can understand the concept of boiling point rise and calculation correctly.

8. The teacher gives students the opportunity to ask questions if the students not understood anymore about the lesson.

c. Closing (15 minutes)

Phase 6 : Make a conclusion

9. Teacher asks student to collect LKS

10. The teacher guides the students to conclude the materials of lesson that they habve learned

11. Teacher asks th question is “do you feel happy and understand the lesson today?”

12. Teacher closes the lesson by giving the tasks of a report to each group and written test in the form of homework (PR) n each student.
