- 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.
- OK.
- I've got mine too.
- Let's look at the aims of the trip first.
- Right.
- What did you have?
- 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.
- I agree.
- And something about finding out how to protect organisms in danger of dying out.
- In our aims?
- But we weren't really looking at that.
- 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?
- 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.
- But not the piece of string to hold up in the air.
- Didn't Mr Blake make a fuss about us leaving that behind?
- Yeah, he does go on.
- Anyway, it was easy to get one from another of the students.
- Now, the next section's the procedure.
- I sent you the draft of that.
- Yeah, um...
- 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.
- OK, I'll look at that again.
- 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.
- I'd expected us to have some sort of high-tech device.
- Not just stand there and count the number of waves per minute.
- Not very precise, but I suppose it was good enough.
- But the way we measured the amount of salt was interesting.
- In the water from the rock pools?
- 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?
- That's right.
- 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,
- So I had to start all over again.
- But at least I'd got the squared paper,
- Or I'd have had problems drawing it all to scale.
- Yeah, it looks good.
- We could get a map of the region off the internet
- And see if we need to make any changes.
- I had a look, but I couldn't find anything.
- But you took some pictures, didn't you?
- Yeah, I'll email you them if you want.
- OK, I'll make my amendments using those.
- Then I can scan it into our report.
- Great!
- Now, when we get to our findings,
- I thought we could divide them
- Up into the different zones we identified on the shore
- And the problems organisms face in each zone.
- So, for the highest area...
- The splash zone.
- Yeah.
- We found mostly those tiny shellfish that have strong hard shells that act as protection.
- But not from other organisms that might eat them.
- Predators.
- No, that's not the main danger for them.
- But the shells prevent them from drying out
- Because they're in the open air for most of the time.
- Right.
- And since they're exposed, they need to be able to find some sort of shelter
- Or cover themselves up so they don't get too hot.
- Then in the middle and lower zones nearer the sea,
- We need to discuss the effects of wave action.
- Yes, and how organisms develop structures to prevent themselves from being swept away
- Or even destroyed by being smashed against the rocks.
- I haven't done anything on the geological changes.
- I don't know what to put for that.
- No, we weren't concentrating on that.
- Maybe we need to find some websites.
- 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.
- 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.
- 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.
- 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.
- 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, though.
- OK.
- We'd better mention that.
