I have never heard about that too, but after I have read an article about this measuring instrument I must confess that it sounds interesting. Let me guess: you should explain and/or use it in terms of the analysis of biological substances, am I right?
It was a diffusion experiment to do with surface area/volume ratio, involving differently sized cubes of agar jelly soaked in phenolphthalein.
I know you guys might be busy but just a quick question, what's the workload like with AS bio? Is it a lot more difficult than gcse bio?
The workload is definitely more than GCSE. There is literally just so much work to do at A-level! It's not toooooo bad at the moment since we're just starting, but as the year goes on it will probably get worse due to studying more challenging concepts.
Having said that, a high workload doesn't always equal a high difficulty... For example, there may be lots of work to do in a subject such as Art or photography, but if your creative-minded then it probably won't be hard for you. The same applies to science. Lots of the content that we're learning is fairly simple to understand, but there's just so much of it that it becomes quite daunting!
From my view at the moment, the difficulty isn't all that high. It essentially just fills in the gaps from GCSE biology with greater depth and detail! But, of course, I may find that later on in the course it gets quite hard haha, we'll see!
Ahhh what A levels are you doing ? ... I want to guess Bio, Chem and History or psychology?
Finished A-levels Failed chem-should have worked more. History isn't my thing. Psychology is a joke at A level, not the difficulty but the subject content in my opinion I did Biology, Geography and Geology You ?

Ahh cool what you doing now then
and I'm doing Maths FM (maybe) Bio Chem and Physics
Can someone possibly talk me through ISA's & EMPA's? How do they work?
Hmmm I'm not too sure on EMPA's .... ISA's i know little :/ I know they are split into Quantitative Qualitative and Evaluative sections though and are more thorough than GCSE ISA's .. you have to calculate your errors etc.
You may want to ask on the Year 13 thread as they will have experienced them
