Mohamedb99 Posted March 15, 2017 Report Share Posted March 15, 2017 Hello, I am finishing up my IA and I realized that I have two dependent variables. My question is "to what extent does the concentration of copper sulfate affect seed germination" my independent variable is the concentration. But I have both the root length and the shoot length as my dependent variables, is that a problem or is it fine? Should I take one out and do just one? Thanks for the help Reply Link to post Share on other sites More sharing options...

c.moes Posted September 9, 2017 Report Share Posted September 9, 2017 Surprisingly enough I have the same type of idea which type of plants did you use, I used mustard seeds but my whole method basically failed since they wont grow Reply Link to post Share on other sites More sharing options...
