Sonneteer_Trombonist Posted March 31, 2010 Report Share Posted March 31, 2010 Maybe the degree of colour change or put in a table whether or not there was a colour change? It's hard to give you any advice without knowing any details about the lab. Reply Link to post Share on other sites More sharing options...
Sandwich Posted March 31, 2010 Report Share Posted March 31, 2010 What exactly is the colour change of? It's hard to say much without a little more info. as to exactly what's going on.For instance if it's a pH change and THAT is why you have a colour change, you should be able to find some way to translate it into an actual pH.I'd also be mildly surprised you've done a Bio lab with solely qualitative data. Maybe it's okay if you're only doing the DC&P part of it, I can't really remember what the specs are, but off the top of my head I'd be suspicious as to how well you could do with an experiment solely based on observation! Again though this depends on what you actually did, I mean I don't know, it could be fine xP It just seems odd to me! Reply Link to post Share on other sites More sharing options...
Charizard Posted March 31, 2010 Report Share Posted March 31, 2010 Color change can be measured with a colorimeter! It gives you quantitative data as it tells you the absorption of a certain wavelength (color) of light. I guess it's too late for that though so include a picture and talk about it. You could talk about the colorimeter in your evaluation. Reply Link to post Share on other sites More sharing options...
