a. Act the dialogue out to your class.

In a senior High School, a number of students is going to have a project in a laboratory.

Speaker 1 : Reverse osmosis! Uh.. this is crazy. What is that? Do you know what it is?
Speaker 2 : A little.
Speaker 1 : I want to complain about our teacher?
Speaker 2 : why is that?
Speaker 1 : He never gives us the complete material we need. Now ... he told us to do this project and I still do not know what I have to do. I think he is not a good teacher.
Speaker 2 : OK! I can explain to you the best thing I know. Reverse osmosis is also called RO. There are two kinds of osmosis namely osmosis and reverse osmosis. In osmosis, two different concentration of liquids separated by a specific membrane will reach equal concentration passing the membrane, will reach equal concentration passing the membrane, the lower will pass the membrane to the higher one.
Speaker 1 : So, what about the other one?
Speaker 2 : Be patience. You mean, RO, right? Reverse osmosis has the same process but the other way around.
Speaker 1 : How?
Speaker 2 : That's the thing that I don't really understand. But, principally, that is the main point.
Speaker 1 : I'm sorry to say this, but I'm not really satisfied with your explanation.
Speaker 2 : So, what're we gonna do?
Speaker 1 : What about asking the teacher?
Speaker 2 : But you said ...
Speaker 1 : It's OK. It's better than doing nothing in the project.
Speaker 2 : Now?
Speaker 1 : No.. next year. Right now, Buddy! Come on!
(They are hurriedly going to the teacher's office.)
Speaker 1 : Good Morning, Sir.
Speaker 3 : Morning. Can I help you?
Speaker 1 :We would like to ask you a few questions about the project.
Speaker 3 : Ou... take a seat!
Speaker 1&2 : Thank you.
Speaker 1 : It's about RO project. We are still finding some difficulties to do the project.
