my idea wasn't really that scientific, so i'm going to abandon that idea and find a new one!
So i googled a lot of things and found that there's an experiment called the "rubber egg experiment" or something like that. it sounds really cool.
So the main idea of this experiment is that an egg (or a number of eggs) will be placed into white vinegar, they'll be in there for a few days then the eggs' surfaces are meant to appear or feel like rubber.
The theory behind this is that the shell of the egg is made up of calcium carbonate, and when calcium carbonate is placed in acidic vinegar, the calcium carbonate will be "eaten up" or dissolves. This will leave the inner membrane of the egg behind and give the egg a feel that's rubber-like.
oooo. sounds interesting. can i eat the egg afterwards tho? ^^
ReplyDeleteisn't it a bit rubber-y to eat? :S
ReplyDeleteDavian, your experiment has no independent and/or dependent variables at all. It's one of the "I wonder what would happen if..." type of experiments. Whilst they can be scientific, I want to see one which is specifically hypothesis testing with valid controls.
ReplyDeleteIf you can't phrase your experiment in the form of: "How does doing A to X cause Y to B" (A= increase/decrease etc, X= independent variable, Y= Dependent variable, B= increase/decrease etc)....
Then you can't actually do the experiment and you won't get approval to do it!
