Control Groups>>>Graphs and Photographs?
Posted: Sat Jan 13, 2007 9:27 pm
Greetings!
Regarding culture dish photos and the science display board, is it necessary to include photo examples of a positive control dish and a negative control dish, in addition to an example of each experimental dish? (Is one example enough for each trial or should you show all three, resulting in smaller images?) Also, do you need to graph the positive and negative controls? If so, should the graph be separate? I guess what I'm trying to ask is if the controls need to be included on the board or does it take away from the experimental group results? Thanx. Happy New Year!
