iodine

Today in science we did a lab about iodine,we learned that it is an indicator.
The lab today was partially successful, the starch in the bag was turning purple, however only a portion.
Mrs.Rosseau stated that it was either the bag wasn't premeable enough or there was too little iodine.
I think that this was an accurate guess, however I was upset that the lab failed and a bit disappointed.
It was still a privilage to do a lab, it was great fun.  The fact that iodine was a potentially serious poison fueled me to  do the lab.
