i was thinking i might do a comparative test of natural dyes/ochres to chemical dyes. the independent variable would either be calico material or hair. the dependent is the dye.
another idea may be to conduct an experiment on the browning/decaying of apples, where the apples are dependent and the conditions/place it is conducted in is independent.
i can test the qualities of both natural and chemical dyes by exposing them to conditions like rain, sunshine, wind and wash them repeatedly. this will all be on the same material, preferably calico.
the apple experiment would require different apples like red, green, Granny Smith, etc.,to be left in controlled conditions and timed until it has become mouldy and brown.
another possible experiment would be to compare the growth rates, differences and similarities of vegetables and fruits. this could be done using similar plants like cucumbers and zucchinis, and completely unrelated plants like strawberries (yum!) and spinach. i already have many fruits and vegetables available in my garden so this could be done effectively within the time limit.
the plant experiment would have to be controlled through the amount of sunlight, fertiliser and water they receive, but that can be easily done when in a pot.
the dye experiment is reliable and fair as i am testing both impartially within controlled conditions with quality and well known dye brands. the experiment will definitely be conducted well within the time frame as the only slightly unpredictable component of the experiment is the weather conditions. i am able to purchase then dye the material at home and expose it to the wilderness in my backyard. finally the result will be VALID, as the quality will have been effectively observed and tested. the comparison of the natural dye/ochre and chemical dye will also be based on the recorded observations.
Yes, this is indeed, very late. But better late than never!

ReplyDeletei think i'll do the dye experiment. it just sounds the most fun.
ReplyDeletei'll use different coloured dyes as well.

ReplyDeletethe conditions are another independent variable, as they are purposefully being controlled.
ReplyDeleteMeera- these need to go into NEW POSTS... not as comments in ONE single post.
ReplyDeleteAnd yes, your dying experiment would work well.
