All the practical components (1 Viewer)

[swordfish]

Can any one help me? im really stuck on heaps of the practical parts of the senior science course. My teacher was pathetic, we didn't even attempt half the pracs in the course and the rest didn't work anyhow. So can any one help out with....
*Modulation, i.e. using CROs to see how a wave can be modulated
*testing the properties of silicone e.g. imperviousness to water, acid resistance
*Comparing the shock absorbing qualities of parts of bones
*Identifying the satellites used for live telecasts from australia to other parts of the world.

hehe, i think thats all. Sorry everybody but im really stuck! Remember drag my marks up and yours go up too, lol :-D

yeah my teacher was crap too and we did hardly any pracs (and never followed up the ones that we did do)

Have a look in the excel book, it gives you are brief description of most of the pracs

Pracs are really important in this course, make sure you not only understand the science behind the courses, but the actual practical aspects, safety aspects, and experiment design facets of each practical.

 

[MiuMiu]

yeah they ask at least one 6-8 mark question about a prac you are meant to have done.

But how can i understand evrything if we haven't done it? i found enough info in txtbooks, etc about the theory stuff we hadn't covered, but i can't find the answers to the pracs.

Best advice is as Year12 said, try to get a copy of the Excel Text book, it shall suffice, your library probably has one...

 

[MiuMiu]

yeah or just buy it, they are $30 but should be reduced at the moment (the excel range is 20% off at most places at the moment)

 

[Delta32]

seeing they cut 20% of the syllabus

 

[MiuMiu]

I think they call it a post-trial special

 

[Delta32]

hehe, yeh, it wouldn't have anything to do with the new excel coming out for next year would it? LOL

 

[MiuMiu]

Is there a new one?

 

[Delta32]

I think so for the updated syllabus..

 

[MiuMiu]

but the excel book only covers what is in it at the moment now anyway doesn't it??

 

[Delta32]

umm, because some of the dot points actually changed quite a bit, they will need to update it, obviously it wasn't financially viable for this year, but probably will be for next...
