4 B. She stood in the wrong place. C. She did it at the wrong time. TRANSCRIPT HELEN: I’ve brought my notes on our Biology Field Trip to Rocky Bay, Colin, so we can work on our report on the research we did together. COLIN: OK. I've got mine too. Let’s look at the aims of the trip first. HELEN: Right. What did you have? COLIN: I just put something about getting experience of the different sorts of procedures used on a field trip. But we need something about what causes different organisms to choose particular habitats (11). HELEN: I agree. And something about finding out how to protect organisms in danger of dying out? COLIN: In our aims? But we weren’t really looking at that. HELEN: I suppose not. OK, now there’s the list of equipment we all had to bring on the field trip. What did they tell us to bring a ruler for? COLIN: It was something about measuring the slope of the shore, but of course we didn’t need it because we were measuring wind direction, and we’d brought the compass for that... HELEN: But not the piece of string to hold up in the air! Didn’t Mr Blake make a fuss about us leaving that behind (12). COLIN: Yeah. He does go on. Anyway it was easy to get one from another of the students. HELEN: Now, the next section’s the procedure. I sent you the draft of that. COLIN: Yeah. It was clear, but I don’t think we need all these details of what time we left and what time we got back and how we divided up the different research tasks (13). HELEN: OK. I’ll look at that again. COLIN: Then we have to describe our method of investigation in detail. So let’s begin with how we measured wave speed. I was surprised how straightforward that was. HELEN: I’d expected us to have some sort of high-tech device, not just stand there and count the number of waves per minute (14). Not very precise, but I suppose it was good enough. But the way we measured the amount of salt was interesting. COLIN: In the water from the rock pools? HELEN: Yeah, oh, I wanted to check the chemicals we used in the lab when we analysed those samples - was it potassium chromate and silver nitrate? COLIN: That’s right. HELEN: OK. And we need the map of the seashore. You just left that to me. And I had to do it while the tide was low, well that was OK, but the place I started it from was down on the beach, then I realised I should have gone up higher to get better visibility (15), so I had to start all over again. But at least I’d got the squared paper
