Sexual Reproduction
in Mammals

By the end of this unit, students will be able to:

• learn about sexual reproduction for the first time;
• build on their knowledge of the life cycles of different animals;
• understand that fertilisation is the process by which a male sperm cell and female egg cell join to form a new life;
• know that other animals, such as birds, fish and amphibians, lay eggs instead of giving birth to live young;
• and identify the different stages of reproduction.
