[Killietalk] classroom advice

[Gary Elson or Mary Frauley <fraulels at videotron_ca>]

Hi,
I was approached by a science teacher in the high school where I teach, 
about the question of finding "an aquatic organism that can be hatched in a 
classroom that will impress the kids". His classroom experiment would begin 
in March and continue through April and May - a very short period for my 
Aphyosemions to be of much use. While I have bred a few annuals to see what 
it's like, they frankly don't interest me much and I don't have any in my 
fishroom.
Does anyone on the list have suggestions about a hardy fast-growing 
(essential with the tight timeline) annual for such an experiment/learning 
process?
