Forgot a Variable~ ^^;;

I forgot to include the controlled variables.  They are:

• the temperature of the milk(when the vinegar is added)
• the temperature at which the casein is allowed to settle
• the amount of milk
• the amount of sun the casein recieves (they need to be put into the sun to dry)
• the amount of time the casein is allowed to settle

I can't think of anymore. T.T
Anyway, I hope that's enough. I don't even know when I'm supposed to hand my blog in tomorrow... Ms Zhang, why'd you have to be away? ;D
