Foreign Perspectives

The results are in a couple of days early as these things usually are.

A year ago I’d have laughed at anyone who’d have said I’d be going down the biology route to my science degree but it turned out that the human biology course was both fascinating and much more doable than I’d ever expected it to be. Fascinating in terms of all aspects of the course really as pretty much all of it was new to me. That newness was something I’d have expected to make the course somewhere between extremely difficult and impossible for me to do but in practice, whilst it was certainly hard going at the start, the fascination drove me on.

For a variety of reasons I’m embarking on my first “proper” biology course next February and, going by the extracts of the course texts that I’ve seen already, it looks like it will be a similar mix of fascinating and difficult. I’ll see how that mix pans out by Christmas next year when the results are in.

I finally got around to making a start on the ECA this morning and, surprisingly, have all three of the short questions finished.

I say surprisingly because when I first looked at them as I was travelling home from the course they looked more like long questions than short ones. I’ll not say a whole lot about them as the second two groups haven’t seen them yet but they’re basically variants of questions that have already been asked during the three themes of the course which I guess is as you’d expect. I only needed to look up one thing in the theme briefing notes which, hopefully, goes to show that I was paying attention during the week.

Next up is the write-up of the experiment. In principle that’s fairly easy but they’ve individual word counts for each section of the write-up which makes it harder. Some of those seem very tight too eg the maximum of 10 words for the title.

All being well, I’m hoping to get a complete first draft of everything tomorrow which is pretty good and will take away my excuse for putting off the astronomy assignment.

Barring more changes from the OU (always possible these days), I’m pretty much settled on doing the main biology course (S204) along with the plants summer school (SXR375) next year.

However, that leaves a few options in terms of short courses that would be nice to fit in around those and in preparation for the plants and chemistry courses. What I don’t want to do is to finish up with the TMA overload that happened  in March this year!

I figure that the plants short course would be nice preparation for the residential as I gather that I may not have reached the plants section of S204 before starting the residential. Similarly, it seems like an idea to get my chemistry back up to speed by way of the chemistry short course before I start on the main chemistry course in October next year. The game plan for both of those is to go for the lower workload rate so there’d be five months to do each of them. Sadly that means that I’d not be able to fit in the fossils course which is on its last run this November and sounds both easy and really interesting.

The disco last night took it’s toll on several people although surprisingly everyone in our group was in by 9.10am.

The final session on plants was the session with by far the most scientific feel about it as we were using all kinds of different techniques and equipment with it. Very much the culmination to the week in every way.

What we were doing was comparing the response of chlorophyll to various types and levels of light. To do that we first had to obtain the chlorophyll which started life as spinach from the local Tesco. We converted this to a liquid by way of mixing with assorted liquids and centrifuging the mixtures. Measurements were taken via a colorimeter after exposing a number of poisoned samples to the various types and levels of light for up to 3 minutes. As usual with the plant experiments this one didn’t produce the perfect results that you might expect but we not only looked the part but felt like scientists for this one.

Lunch was a little complicated as my usual addition to the meal of a couple of bottles of water wasn’t a runner when I was off to the plane so instead sweeties for the kids needed to be used to reach the magical £7. We’d a somewhat hurried lunch as the final lecture was to start as soon as we’d all sat down in the lecture theatre (yeah, we could all have gone down the take-away route, but nobody thought of it!).

The wind-down lecture concentrated on the ECA for the course which was handed out to us at the end. As expected it’s a write-up of one of the experiments (I’m going for the differences in respiration rate of brain and skin from Wednesday morning) and one short question from each of the themes. Well, they are titled short but some of them look relatively long to me but I’ve done little more than glance at them so who knows. Some of them look a little scary at the moment but then a lot of TMA questions can look scary at first glance.

Quite why they don’t hand the ECA out in advance is something of a mystery. We all knew that there was going to be a research write-up plus three questions before this week. Similarly we knew that we’d have to choose one of the nine possible experiments or rather eight as there’s one that doesn’t really work as a write-up. Likewise we knew that there’d be a short question on each theme and, really, it wouldn’t matter for the week if you did know what they were (I’m not going to say though or I’ll get told off… again).

Unsurprisingly we didn’t use Practical Biology today so we’ve all been lugging it around all week for nothing. I don’t even think that it’ll be needed for the ECA either. More annoyingly, some people appear to have incurred excess baggage charges thanks to bringing it along (as would I had BMIBaby weighed the case).

Useful to know is that Lenton Cabs (0115 9 781 781) only charge students £19 for the airport run vs the £35 of the airport taxis (and, yes, they can pick up from the airport for the same charge). Oh well, something to bear in mind when I’m doing the level 3 residential next year.

On that level 3 residential, it would appear that the majority of people are doing both of them next year rather than splitting them between 2011 and 2012. The reasoning for most seems to be that since 2012 will be the final year there’ll be a combination of a winding down feel in 2012 and a very high chance of the courses filling up extremely early. In terms of recommended pre-requisites, SXR375 (the plants one) requires S204 so that’s OK for me in 2011 but SXR376 (the human disease one) requires S320 or S377 which I can’t do ’til 2012 so that’s the best year for the second residential for me.

As usual, post-residential I’m exhausted.

It was on to plants this morning which I know nothing about other than what was in the background reading material.

First off we were given an overall briefing on what we’ll be doing over the three sessions before we broke up into our two subgroups.

We were looking at how carbon fixing in plant leaves is affected by a range of conditions which we selected. We chose to look at the differences between the upper and lower surface of tobacco leaves and set about drilling 10 holes in a leaf for each of the two surfaces. Since we didn’t want carbon to sneak in the other side we’d to put a layer of vaseline on the filter paper we were using. Then it was off to the tutor so she could add the mixture to create our radioactive carbon dioxide.

Although it looked like it would be incredibly fiddly to do it worked out well and after tea we set about testing the various samples that we’d created by way of the Geiger counter. As always, the whole process took longer than I’d have expected at the off so it was quite a late lunch today.

With the statistics involved I thought at one point that we might need the big green book but we didn’t as all the necessary information was in the handouts. So I’ve been lugging it around for no reason at all.

After lunch we were joined up in one 24-strong group to do an experiment on the stomata of a plant. The reason why we were operating as a large group became very clear when the results were ready. They were all over the place with next to no consistency between groups. Basically an experiment that doesn’t work too well and the only total failure (so far) for the week.

For some reason plant experiments take even longer so we didn’t get away ’til after 5pm this evening which doesn’t bode well for tomorrow when I really have to get away on time.
