Biology design nightmare...;)

Hi,

I have to write my first bio design, more or less I know how to do this and my question is do you (experienced IB students ^^) have any good advises or methods to write bio design (and in time) ???

It seems like a nightmare to me, lab reports are enough complicated and design is much more difficult. :P

Thomas, it's one of the three evaluation criteria for biology lab reports. As you probably know already, your lab report should include an introduction as well as a quick overview of the material and the methods used (just refer to the instruction sheet if you got one), in addition to the results as well as conclusions and evaluation. Design is assessed in the first two, DCP in your section concerning your results, and finally CE in your conclusions and evaluation.

Your best friend here will be the biology syllabus, as it explains exactly what's required from you. Basically aspect 1 is assessed in your introduction and aspects 2 and 3 in your section about material and methods. The intro should include background information (quoting and referencing the book is a good way) to the phenomenon at hand as well as the aim of the experiment and any hypothesis that you can think about. If you've learned about it already you should also include the key variables involved. Check the biology syllabus, it explains what you should write in terms of the three aspects within the design criterium.

Is this for the new 2009 syllabus? Because I only remember the criteria as Pl(a Pl(b DC DPP CE MS PS(a and PS(b. In those I don't remember anything about design, the only thing similar is planning. So I am not sure if I can help you.

Yes, this is the core syllabus that was implemented this year, so therefore it's valid for the exams of 2009, which is what I supposed harmonicgirl is doing since she's only starting on her biology lab reports =)

The new syllabus involves only three criteria -- Design, Data Collection and Presentation, and finally Conclusion and Evaluation. Each of these is then broken down to three aspects with their own assessment criteria.

Actually, I think Design is the easiest part of lab reports because you don't have to do any data processing, and the results don't matter so you can choose almost any method without worrying about things going wrong.

You just have to be very specific about everything, even those small details you think are completely unnecessary. For example, if you use a beaker, what volume? If you measure up a specific mass, how do you do it? Think "instructions for retards", because it's supposed to be easy to understand for everyone. And don't ever ever forget to state that replicates of the whole experiment should be made. The key is to be specific.

Thx :P

Maybe it's not so bad as I thought and syllabus was useful XD I hope it's not as difficult as my teacher told me it is... Now I have to start thinking about the subject and method, what's not so easy.
