This week I made the mistake of letting a student, who is quite enamored with sea stars, do an experiment on the only sea star in the lab, by cutting off its arm and measuring the rate of regeneration. I hesitated when she asked permission because one really can't do an experiment on only one animal. Funny, because when I'm at home with my little kids I have no problem saying, "NO". But with older kids who aren't mine, I realized it's not so easy...until now. She begged. I caved. As a result, we have a dead sea star (who theoretically should have survived and regenerated an entire new arm). But then again, who can predict what will happen with animals in captivity?
In hind site, I should've known better. Next time I will apply all the skills I've learned and mastered at home for the last five years : "The answer is NO!"
