2) Without reading handout, students can decsribe the work principle of microscopes correctly.
b. Process
By given figure of microscope, student can explain how microscopes magnify objects by their own language correctly.
2. Psychomotor

VII.LEARNING ACTIVITY
A. Introduction (5 minute)
a. Teacher asks students to observe an image of note by using a drop of water and a bottle of mineral water or plastic. Then, ask them”what have you observed? Is image of note became smaller or bigger? Why a bottle and a drop of water can do that? ”
b. Teacher explains the learning objectives and explains what students are expected to do. Students are expected to create an economist instrument that can used to observe microscopic.
c. Teacher establish positive attitude toward the lesson.
d. Teacher recalls the previous material about light and lens.
e. Teacher checks the pre knowledge of the students about optical instrument.
A. MAIN ACTIVITY (20 minutes)
1. First phase : Orient student to the problem
Teacher shows a leaf, and then asks “Can you see what inner this leaf is? I can show a picture of this inner leaf (show an epidermis picture). Do you know how expert can observe cell of leaf? It’s impossible if we observe it by our eyes directly. It is use an instrument, optical instrument. The exactly is microscope.
Teacher decribes why scientis use microscope to observe microscopic object. But, microscope is expensive enough which is other costs and benefit of it. How excitingthing if we can make simple and economis microscop by recycling some material arround us. Therefore all of student are hoped to take part in this investigation. Guys, do you any idea how can we make an economist and simple microscope?
2. Phase Two: organize student for study (5minutes)
a. Teacher makes study teams at least consist of two members on each group heterogenously.
b. Teacher organizes cooperative learning.
Mangement time:
- Time allocation is 1 x 45 minutes
- Introduction (5 minutes)
- Phase 1 (5 minutes)
- Phase 2 (5 minutes)
- Phase 3 (20 minutes)
- Phase 4 (5 minutes)
- Phase 5 and closure (5 minutes)
c. Teacher asks student to rewrite the problem and make a hypothesis.
3. Phase three: assist independent and group investigation(20 minutes)
a. The students read handout and article. Then discussing material under teacher guidance.
b. Conduct experiment, teacher gives tool and material for each group and ask student to write this activity in student worksheet, with form tittle; outcome; design of experiment; procedures; data gathering; hypothesis; explanation of solution (see more in enclosure).
c. Student start to investigate during time given under teacher guidance and examine the hypothesis.
4. Phase four: develop and present artifact and exhibit( 5minutes)
a. Each group is asked to present their simple microscope and their report.
b. Other groups may deliver some questions or ideas of their friend presentation after allowing by teacher.
c. CLOSSURE
5. Phase Five: analyze and evaluate the problem-solving process
a. Teacher guides students to check their report entirely.
b. Students are asked to answer the motivation problem based on introduction. The answer is a bottle and a drop of water can be a convex lens and make an image smaller. Therefore it can be used to be a simple microscope.
I. Evaluation Learning Outcome
A. Cognitive assessment
B. Psychomotor assessment
C. Affective assessment
