Title: ERI
Post by: WhoTookMyUsername on April 03, 2011, 01:20:55 pm
for unit 1 our extended research investigation is to construct a 3d model of an ionic compound, covalent molecule or covalent lattice with a Mr of 30 - 200

Must be no bigger than shoebox and we have to present an oral presentation of the history, properties, nature, hazards, development, limitations of model etc.

I have no idea what molecule to do! Something simple and easy to discuss and construct, but no so simple that it loses marks for that!
Thanks

W.T.F.

Isn't this like 6 weeks away?

Ooh, I feel sorry for you guys.. I never had to do this :P

Choose NaCl, who cares if you lose marks for it being "simple" (getting it right will still be a bitch; even spacing, relative atom size etc. ) -- at the end of the day all you need for 1+2 is a pass.. and you will lose very few marks, if any, for choosing a basic ionic structure.

Do a fun one:

aspirin
D-glucose
nitroglycerin
diamond
graphite
sulfuric acid (in water)


Those are the ones that I remember best

I thought maybe something covalent is easier, no need to make it a lattice etc, just a simple 6 piece thing?




Ah yeah, I didn't realise you could do covalent when I posted...

Do CO2 :P

It's other name cracked me up when it came up on the 09 Olympiad

But in all seriousness, you should pick something very simple like NaCl, CO2 etc, as the report you write needs to be informative.
