.Ask parents or other adults to collect polliwogs or tadpoles from a pond.
.Put them in a small bowl with the original pond water and let the children watch them grow into frogs.
.The bowl should be emptied every day and replaced with fresh pond water.
.This will provide natural food for the tadpoles.
.Supplement with tiny amounts of goldfish food if needed.
.If you are unable to provide good living conditions for the tadpoles return them to their natural environment.
