sb+immune+SAC

One of the criteria for the immune response SAC requires you to show your progress in developing your presentation. On this page you should have the following. You should show your planning of the presentation, such as the images chosen and information you want to convey. This includes how you broke up your topic into the various sections. You should also include why you sequenced the images the way you did and the collating of information. It is important that you acknowledge any sources of information (including images) below. You will also need to upload your audio file onto this page.

I chose to study both antigenic mimicry and antigenic variation, as there is not too much information on either in any of my resources, and when all combined together, just makes up 5 minutes worth of information.

In my preparation of the script i first described antigenic mimicry, then antigenic variation and finally the use (or uselessness) of vaccines against them. In both topics they are split into a general description, background information needed to understand the concept (where needed) and an example of the pathogens defense technique

after writing the script, i began systematically moving through each part that i believe needed a diagram and creating them on Paint. i find this technique much more useful than getting images off the internet (as this is not a highly discussed web-topic). Diagrams drawn include pictures of self and non-self markers on bacterium and self cells, B cells and their antigen receptors, etc. Some pictures from the internet have also been used. So far i don't have any decorative pictures, only diagrams that assist in my explanation.

In periods 5-8 this tuesday i wrote out my whole script, created 7 slides (though the school computers helpfully deleted most of them which i had to continually replace) and recorded myself, so i only have the rest of the slides left to draw. This is very satisfactory for me. -on the thursday following this, a day before the sac, i had major computer/KDS troubles. but i have succeeded in making all the slides and recording the speech. I have not yet combined them on windows movie maker as i think it is a silly application and technological issues arent my fault.

difficulties: -i find i can only describe antigenic variation properly through the example of Trypanosomes (a species of protozoan) even though i dont know what trypanosomes are, how to pronounce it, or what sleeping sickness is. Nor is this an example discussed anywhere else in cyberland, from what ive found (or more from what i haven't found), and so a graph that i describe in the audio might have to be drawn on the computer, which will be a challenge to do correctly. -I find that, because of the content and voice unfit for recording, the presentation can become boring, and even when i listen to it myself i find myself drifting off and getting distracted. This is very bad! -stemming from the last problem, if i try to accentuate key parts people need to listen to, i waste time -and stemming from that last problem, i'm already 6 seconds over my time limit -i feel i haven't fully explored the medical side, but i don't want to insert any more at the expense of other information or the clarity/speed of the speech. -laziness: its already recorded, which is a harrowing task indeed and one that i've done 3 times now, and i don't want to do it again even though i know i need to.

Solution: -record again, writing points that are important in bold, and cutting any repetitive remarks from the speech -inserting slides that will only flash up (namely, "self", "nonself" and "trick") that will be bold and black and white and capture the audiences attention (but hopefully not distract them) if their mind starts to wander. (all that analysing of paintings in art finally pays off here!)

some of my pictures (mostly made on paint)

my sppech/recording - i thought it would be better just to give you the document than go into detail what ive already described in the second paragraph, above
