Experimental design HELP!

[Coolgalbornin03Lo]

What are possible experimental design topics for chem?

I’ve got electrolysis (electroplating), volumetric analysis and calorimetry. Are there anymore?

What would be some systematic and random errors for each? I don’t understand these in chem they seem different from biology. Like I understand systematic error to be something which causes a consistent variation in measurements (I.e incorrectly printed measuring cylinder) whilst random errors cause something to vary by an unpredictable variation. However in chemistry they start talking about how much liquid is in the flask etc.

I thought you increase precision by repeating but apparently in chem you don’t?

 How do you increase accuracy, reliability and precision? I would look in the text book but there’s no chapter for this!

Anyone have any resources which can help? But obviously not copyrighted materialsbecause that’s against atarnotes policy! I mean resources like websites and YouTube vids

Hi Coolgal,

I did see some experiments (mores in company exams) related to affect on pH and temperature on enzyme function. Its probably worth looking in to!!

As for resources (I thought there was a chapter in the textbook??) VCAA has information on their website with all errors, etc.
