Animal gestation periods

In this Reproduction and life cycles: animals unit, pupils learn to describe the life process of reproduction in some animals. In the Evolution and inheritance unit, they will build on this knowledge to learn that living things produce offspring of the same kind, but normally offspring vary and are not identical to their parents

In the New life unit, pupils learnt that animals, including humans, have offspring which grow into adults. In this Reproduction and life cycles: animals unit, pupils will build on this knowledge to describe the differences in life cycles of different animal groups

This unit explores the life cycles of mammals, amphibians, insects, and birds, and the reproduction process in plants and animals. It focuses on recording data, presenting findings with conclusions, and evaluating scientific evidence to support or refute ideas in various presentation formats.
