Improvements on experiments??? (1 Viewer)

[Snapwizard]

I read the 2002 hsc and was wondering what to wright when they ask you how to improve an experiemnt?
The question is for physics but it relly dos't matter that much!!
Pick any random queation (thus the 2002 HSC one)
Thanks??

well theres heaps of things, depending on the practical istself... like repeating the experiment 10000 times to get a more accurate result... umm.. have controls and variables...
and yeah.. thats all i can think of right now.

there r the obvious ones, like repeating etc. But it depends on the experiment. Some experiments may have a weak spot that is vulnerable to inaccurate results if something is not done.

yeah that one is always the case... use when the equipment u use is bound to case errors.. eg. a stop watch.

human errors can often be used.

IIRC the one in the 2002 HSC was right after the multiple choice . It's fairly straightforward...look at the procedure for the experiment and ask yourself where things could go wrong . IAW Malachite as well.
