Tadpoles to Frog life-cycle

A couple of weeks ago I went on an adventure to find a stream. Once we got there we found loads of tadpoles. I collected about 10 and brought them home in a bottle with stream water and pond weeds.

How I looked after them:

When we got back home I put them in a washing up bowl with 3 litres of mineral water (don't use tap water it will kill the tadpoles - if you do not have mineral water then you can use rain water) 2 weeds with roots (the tadpoles will like to eat the roots of the weeds) and rocks to climb on once they have limbs (otherwise they will drown).

Here is a picture of a life-cycle I made:
