school project with tadpoles.

[damzookeeper]

HI, wondering if anyone can help me out a bit more. My daughter came home with 3 tadpoles from school. The class is doing a school project with them. She is supposed to take care of them till they turn into forgs and then release them back into area where they came (her teachers back pond)
As far as we know these are spring peepers. The good news is that she said there are litterally thousands apon thousands in her back pond. Way to go peepers!! lol.
Anyway, We went down to the nearest pond and grabbed some water and seaweed. I have it in a small tank and now I want to put the tad poles in. They are presently in a jar with water from the tank at school (pond water, but it has been inside for over a week so temps are warmer, than ours) Should I put them in a bag and place the bag in the tank for 1/2 hour or so like you do with fish, or should I wait till morning and just dump them in. I would think the bag, but I have never delt with tads before. I know they can't be touched and they live off the algea in the tank and fish flakes but I want to make sure these guys servive. My daughter will be so happy to see them change into frogs and then to release them will be an experience for her. She is 8 btw.
Thanks for any info or help in advance.

Just thought you would like to know, we own a spanish ribbed newt and a white lipped tree frog, also have had salamanders in the past. Other than this though, we haven't owned any other amphibians, only lizards. Thanks.
