it's a yes!

Ok so recently Ms Zhang gave me a 'yes' so I'm going to stick to what I've been thinking about for SRP for the past who knows how long time ago. Okey dokey. so here's what I'm officially going to do for the time being.

Experiment: Various liquids v.s an iron nail.
Aim: To hopefully conclude which liquids rust an iron nail and if so, which is quicker/quickest at doing so.
Apparatus: ~5 iron nails
~5 teacups
~5 different types of liquid
~1 tray to hold teacups in

In this experiment, I have chosen to use:
IRON NAILS - because my dad has bucketfuls in his little shed
TEACUPS - because my mum likes coffee now and that they are ceramic
TRAY - to make sure that if there IS any spillage of liquids, it doesn't go onto my lovely table

When I conduct my experiment, I will be keeping the cups of various liquids with iron nails in them on my table, which is a suitabe place because I got there everyday. I mean, who doesn't? And so that no-one touches it and so that I will be able to keep a close eye on and observe any unexpected changes/explosions/popping phenomena/whatever will happen but hopefully wont etc.

At the moment, I'm still trying to grasp an understanding on what is dependent and what is independent. So I am controlling the time in which I will be leaving the iron nails in liquid so every nail spends the same amount of time in each liquid under the same room temperature and conditions. If one of the cups fall down and break or whatever, I will start the whole experiment again because then it won't be a fair test because the other nails would have had a longer time bathing in the liquid.

I am observing and therefore will no be able to control, the amount of rust, the rate of rust and the time in which the rust will appear, on each of the iron nails.

Something I will keep consistent in this experiment will be the type, shape and size of the iron nail. Of course, they will all be iron and they will all be from the same company, in case other iron nail brands aren't made from iron??? Who knows...
And I will also be pouring the same amount of liquid in each teacup so that one nail doesn't just rust because the cup is overflowing or something.

Also, I'll try not to place one side of the tray in sunlight while the other side is suffering in the cold darkness of my room. It's either that the whole tray is fully exposed to sunlight or it is kept in complete darkness. I'm not sure whether this will even have any effect on my experiment and what I'm testing but just to be on the safe side, I will attempt to guard the iron nails from the sun. Haha.

I'm going to leave the nails for some amount of time before concluding my entire experiment, but one thing I will definitely be doing is recording down any changes or no changes :( as to whatever happens to the nails. I will be most likely be doing this daily. Or for every three days because by the time I actually get to this experiment, I might find something else to occupy my time. What if there's something on TV? Who knows...who knows....Yeah. So I'm guessing that a checkup every three days aint so bad so that's what I going to do. I think it's also good to take pictures so I have visual evidence in case I have dodgy descriptions of things which is most likely so I'm going to take pictures definitely. Oh great. I'm going to take pictures of iron nails in teacups. Charming...

So that's all I've got time for at the moment, or can think of as for now, so until next time!
