mashya Posted July 30, 2008 Report Share Posted July 30, 2008 (edited) I'm thinking of doing my extended essay on something that is related to plant growth Things i fell upon were the effects of various fertilizers and the effect of ph (Acid rain) on plant growth. But i'm not sure they work.. I don't see how i could do more than one experiment with these and manage to write 4000 words (plz tell me if I'm wrong) So ya, what's the next step? Any help is very much appreciated Edited July 30, 2008 by mashya Reply Link to post Share on other sites More sharing options...
Gwib Posted July 30, 2008 Report Share Posted July 30, 2008 Problems with plant growth in an EE is error. Plants are never the same, amount of stomata varies, size of leaves vary, height and a million other things. The acid rain one sounds interesting, you could see effects of different pH's (dilute the same solution of 'acid rain' different amounts). Just make sure that you can take lots of measurements. EE examiners luuurve tables and graphs. Reply Link to post Share on other sites More sharing options...
