Hi!
So one of my assessments is to do an experiment to model natural selection, I chose to use jelly beans, and so what i did was I had half a cup of jellbeans scattered on a plate and asked my volunteers (predators) to pick out 5 of their favs - did this three times. After that i recorded that the black jelly beans were the one's that survived as no one took them.
And so I need to imrpove on this and repeat, I just was wondering, as a limiation of the experiment was that I didn't know the accurate amount of each colour of jellybeans (there are 9 different colours) and If I made each colour proportional I would get more accurate results.I can only think of that one limitation/ difficulty in my experiment, just by reading this can you think of any other problems?!!?
ALSO as I need to repeat this experiment again, should I cut down the number of colours to say 4/5 (inlc. black) and make each jelly bean 8 each for each colour?
I'm finding it hard to sort of modfiy and make it more accurate, all the help and comments would be appreciated!![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
