Science Practical Portfolio (1 Viewer)

[StaceyK293920]

Would anyone happen to have a science practical portfolio for each science practical typed up and listed? (e.g. Chemistry - Gravimetric Analysis of a Mixture), also listing the variables with the conclusion?. If you do, would you mind attaching it to this thread or sending a PM with the file? This would be greatly appreciated!

Thanks .

Here's some of mine. Not sure I did the variables every time, though:

There's probably one more, that I can't find at the moment. Sorry.

lol, don't be sorry

Thank you so much Aerath . Now all I need is the physics and biology practicals.

Thanks again Aerath, really appreciate it!

I'm thinking of asking the current year 12's at my school for their chemistry notes - haha, it would be so helpful and save alot of time and effort

Nice work Aerath, I needed them as well . I'll probably try and make physics and biology myself, otherwise, if someone can post them, that'd be great .

My Physics ones were hand written.

By the way, if anyone [*cough* Eric (The Kaiser)] can post a Chem Prac about Magnesium Oxide, that would be great.

here's another gravimetric analysis - if you want it

by the by - well done aerath - outstanding

 

[bored of sc]

we should do this for every subject!! (except maths and some of english for obvious reasons)

is that the one where you compare the physical and chemical properties of the reactants and products?? it was for us - it shows the physical and chemical properties of the reactants (for our experiment the reactants were magnesium and oxygen) are different from the properties of the product (s) [magnesium oxide]

 

[Aerath]

Nah, it was something to do with the ratios, how Magnesium and Oxygen combine in the ratio of 1:1, and we had to use Atomic Masses to prove that.

My computer can't upload Microsoft Works files as attachments unfortunately, but if you and the other members want to see my all my Practicals, just feel free to PM and I'll copy-paste it directly, but be warned it will be long.

oh okay - i think we covered that ratio concept through the electrolysis of water - cause hydrogen and oxygen are in a ratio of 2:1 respectively so the amount of hydrogen is double oxygen with water is electrolysed (i think that is a word)

Would anyone happen to have a conclusion for 'the effect of surface area to volume ratio on the rate of diffusion?'. We used agar cubes to investigate the diffusion rate of agar cubes, which represent cells.

Thanks.

Edited:

Would anyone also have a conclusion for the osmosis and diffusion experiment? The equipment we used was a dialysis bag with starch and Iodine mixed with water solution. We left the experiment for 24 hours and the dialysis bag turned a differnet colour and when shaken, it went black. I'm just not sure how to write a conclusion.

All help is appreciated! Thanks.
