HELEN: Yes, and how organisms develop structures to prevent themselves from being swept away, or even destroyed by being smashed against the rocks.
COLIN: I haven’t done anything on the geological changes. I don’t know what to put for that.
HELEN: No, we weren’t concentrating on that. Maybe we need to find some websites.
COLIN: Good idea. I’ve got the lecture notes from Mr Blake’s geology course, but they’re too general. But we could ask him which books on our Reading List might be most helpful.
HELEN: Right. OK, now I did a draft of the section of sources of possible error in our research, but I don’t know if you agree. For example, the size of the sample, and whether it’s big enough to make any general conclusions from. But I thought actually we did have quite a big sample.
COLIN: We did. And our general method of observation seemed quite reliable. But we might not be all that accurate as far as the actual numbers go.
HELEN: Yeah, we might have missed some organisms – if they were hiding under a rock, for example. I wasn’t sure about the way we described their habitats. I decided it was probably OK.
COLIN: Yeah, and the descriptions we gave of the smaller organisms, they weren’t very detailed, but they were adequate in this context. I’m not sure we identified all the species correctly thought.
HELEN: OK, we’d better mention that. Now, how …
