Do you think

Music's effects on plant growth

would be an approporiate biology experiment for

extended essay (IB) ?

I know that have "music" as a variable sounds silly, but

how could I set the variables so that the lab can be

analysed in depth ?

mythbusters did an episode on this, deprived of water, hard rock gave the best results.

 

to set it up as a lab experiment, you'd probably set up multiple identical plants in sound proof boxes with white noise filtered into different bands of frequency (you could use music but i myself have favourite bands and you probably have no way of asking your seeds). oh yeah, and have a control batch to measure against.

 

use fast growing plants so you can repeat and test other variables.

 

tell us how it goes, i'd be interested if you could get any real results.
