H. Teaching-Learning Processes
1. 1st lesson
Introduction (10’)
Guiding questions:
- “How to make a group of matters in our daily life into acid, base, and salt?”
- “What are you going to use to identify and classify the matters into acid, base, and salt?”

Activity (30’)
Divide the students into small groups.
Each group will discuss the definition of acid, base, and salt.
Each group will do brainstorming to find out what kind of nature materials they can be used to identify and classify into acid, base, and salt.

2. 2nd – 3rd lesson
Ask the students to do research from books, internet, and other resources to find out what kind of natural materials that can be used to identify and classify acid, base, and salt.
Ask the students to make a plan to prove if some natural materials can be used to identify acid, base, and salt through doing experiment.

3. 4th lesson
Ask the students to do the experiment and prepare the presentation.

4. 5th lesson
Present the result of the project.
