All animals produce young which must be cared for by the parents. We see a snake and an ostrich hatching from an egg. Not all young animals look like their parents. A baby ladybird and a tadpole are shown as examples of animals which do not look like their parents.

View the clip, then ask: "What do all the animals NOT born from eggs have in common?" Replay the clip so the children can note the common features of these animals, such as: they all have fur or hair, they all have four legs and the babies all look like tiny copies of their parents. Tell the class these features can help us work out whether an animal is born from an egg or born alive. Sit the class in a circle. Ask children to take turns naming an animal. Each time, the next person in the circle should reply "egg" or "born alive" depending on the animal named. For example, "monkey" gets the reply "born alive" while "slug" gets the reply "egg". Are there any exceptions to the rule? Pupils could list hard-to-classify creatures and check information sources to confirm whether they are egg-born.
