so once again ive decided that my srp is going to be called ' what is the best way to stop cut apples from going brown'.
i have no idea how this is going to work but im going to give it a go... right now
firstly...
i think i am going to need:
- LOTS and LOTS of similar sized room temperature apples (approximately 5 or 6)
- big bowls
- stuff to dip the apples in like vinegar, oil, water, apple juice, salty water, sugary water etc.
- a knife to cut the apples with
- a chopping board to cut the apples on
and then...
- first i cut the apples into halves, or quarters, or eights...or sixteenths.
- then i fill the bowls with enough dipping stuff to cover the whole apple.
- then i dip the apples in the stuff and i observe the changes.
in the end...
it should probably take about 1 day but i could repeat it lots of times or do different situations or something.
however...
im thinking that i should do 1 apple where i dont do anything to it. but then i dont know. should i soak the apple in it or should i just paint the apple with stuff? coz if i soak it, thats a lot of oil im gonna need. and then what do i do with it afterwards. but painting the apples with stuff looks really dodgy.
oh and im thinking that my independent variables would be the different substances and the dependent variable would be the brown-ness of the apples. and the controlled variables would the amount of substance the apples will be dippied/painted in.
i think...
i think...
bye.

One of the key things you need to be careful about is the depth of your discussion. You need to make it at a year 10 level, despite how easy your project is.
