Science fair worm experiment
Sorry in advance for the long post. I have searched the archives but didn't really see specific answers for this situation.
I've been lurking here for quite awhile and have learned a ton--thanks for making this such an informative and friendly forum!
Here's my question: my son, who's in 5th grade, wants to do his science fair experiment on worms and I thought I'd check in to see if anyone has any advice for us. His idea is to set up 5 or so small bins (shoebox-sized, more or less) and see which of several different foods the worms like best. We'll put the same number of worms in each bin and measure how much of each food we give them. I know we should only feed them tiny amounts, but my concern is that in such small bins it will be difficult to keep the conditions ok for the worms. Does anyone have any suggestions to keep the worms alive for several weeks in tiny bins so my son's experiment doesn't get ruined?
