Listen to a conversation between a student and her biology professor.
Hi, Jean. how was the...uh, the conference,right? The conference on volunteerism? That's where you were last week.
Yeah. It was great.
I met a lot of people from some really amazing organizations that are working in the area.
Now it would be a lot easier to get students to volunteer in the community.
Plus, I have never been to any of the beaches here before.
Being at the beach was definitely a plus.
Well, I hope you had time to look over the notes from the class you missed.
You did get the notes, right?
Yup. I'll look them over before tomorrow's class.
Good. And let me know if you have any questions.
Well, there is something that I wanted to ask you now. It's about something I noticed at the beach.
Oh , what's that?
Well, see, there are a lot of jellyfish there, floating in the water.
That couldn't have been pleasant.
Not for swimming. But it was interesting.
I mean, the jellyfish were glowing. I swear they were. And I am wondering what that's about.
Ah, glowing jellyfish. That is interesting. Uh, it's called bioluminescence.
And actually we are going to talk about it later in the semester.
Basically, bioluminescence is light that's produced by a chemical reaction.
Really? Inside the jellyfish?
Well, not all jellyfish, about half of them.
Actually,a lot of marine organisms have this ability, especially in deeper parts of the ocean.
