The Billy Lids

First, collect some frogspawn in a jar. It can usually be found at the edge of a pond in early summer. Keep the frogspawn in the pond water.

Tadpoles need to take oxygen from the water so it is better to put them into a container which has a wide top when you get home. Scoop up plenty of pond weed to put in the container as well, and put in one or two large stones. Later on, as they begin to turn into frogs, the tadpoles will need to climb out of the water to breathe.

Watch the tadpoles as they hatch from the frogspawn. At first, they eat the jelly surrounding their eggs, then tiny animals in the pond water. Keep them supplied with plenty of fresh pond weed and pond water.

As their legs appear, feed them with little pieces of raw meat, but don't leave uneaten bits to rot in the water.

Once their front legs begin to grow and their tails start to shrink it's time to return them to the pond where they will gradually spend more time out of the water, as they develop into adult frogs.
