　　Script:

　　Narrator: Listen to a conversation between a student and his environmental science professor.

　　Student: Hi, Professor Williams - I(m here for our 1:30 meeting.

　　Professor: Hi Michael. Thanks for being so prompt. That really makes

　　a difference when I have so many students scheduled back to back. If only there could be more than 24 hours in a day.

　　Student: (Laughs) I know what you mean.

　　Professor: So, what’ s on your mind?

　　Student: Well I’m here about my topic choice.

　　Professor: For the upcoming oral presentation? By the way, how do

　　you feel about speaking in front of the class?

　　Student: Well I’ d have to say I’m most comfortable writing

　　papers, but I’m not nervous about doing this presentation. It’ ll be good public speaking practice you know.

　　Professor: Exactly, and certainly, it’ s a skill that is always useful.

　　Student: Mm-hmm. Yeah, so the assignment was for us to talk about

　　a current environmental solution? And I found so much eye opening information while researching. The only problem is, I don’t know which area to go with.

　　Professor: Okay well, which areas most interest you?

　　Student: Well I’ve spent a lot of time exploring the concept of wind

　　farms. You know, using wind as a source of energy.

　　Professor: Mm-hmm, go on.

　　Student: Right um - lots of stuff on that you know types of wind

　　farms and different designs, how they' ve been set up, how to get the most out of them.

　　Professor: Okay, and what' s another choice?

　　Student: Well, it' s a tie between wind farms and mushrooms.

　　Professor: Mushrooms!? Hm! Tell me more about that!

　　Student: Well, there' s a species of mushrooms that produces

　　chemicals that can eat away at toxic waste - from petroleum products, pesticides and other harmful pollutants

　　Professor: Yes, I've read research about this - but actually Michael

　　it' s the fungus beneath the ground that affects the harmful pollutants. That' s an important difference

　　Student: Oh ri-right that' s what I meant - I'll explain it more

　　clearly in class.

　　Professor: Keep it simple. Something like - just like trees produce

　　apples, it' s the funghi that produce mushrooms - and it' s also those funghi that produce the helpful chemicals.

　　Student: I understand - it' s just so amazing that something low

　　cost and already there in nature could solve such a large pollution problem caused by humans

　　Professor: It is intriguing. Wind farms affect, too, but I think most of

　　your classmates will already be generally familiar with that topic. Whereas they might not have heard of this.

　　Professor: Btw, what s the growing period for this species?

　　Student: Ah it only takes a month to grow.

　　Professor: Great! The university has a greenhouse that's sometimes

　　available for research projects. Why don't you stop over there one afternoon, speak to the manager and ask if he' d let you use a small area of the greenhouse?

　　Student: Okay.

　　Professor: You could try to duplicate the results of the study!

　　Student: In the greenhouse?

　　Professor: Yes! You have three months until the end of this semester.

　　It might make a strong final project!
