What will students learn		Students need to describe the process of selective breeding by identifying desired characteristics. Explain how different species of plants and animals are adapted to the particular environmental conditions in its habitat. Identify different characteristics as being inherited, caused by the environment or a mixture of the two and know that there is variation between individuals of the same species. Understand the main changes which take place during puberty and the interplay between the male and female reproductive organs in bringing about fertilisation. Know the main structures associated with the development of a foetus inside the uterus and the importance of the menstrual cycle in human reproduction.
Key Knowledge that students should know at the end of 'Topic'	This is the knowledge that students will meet for the first time in this topic	The process of selective breeding, how it works to produce offspring with desired characteristics. How different organisms having variation between individuals and is importance for the survival of that species in a changing environment. How factors could affect environmental variation and which factors are categorised as continuous and discontinuous. What biodiversity is and how important it is in ecosystems. Name the changes to the bodies of boys and girls during puberty the key features of the male and female reproductive systems. How a foetus develops from sex cells to birth. Identify the key events in a 28 day menstrual cycle in a non-pregnant woman and how different contraception methods work in preventing pregnancy.
	This is knowledge that students may have met before but will need to deepen their understanding	Students should have basic knowledge of certain plants and animals that live and are adapted to particular habitats. They should have basic knowledge of different characteristics that are inherited by parents and caused by the environment. Identify some of key features of the male and female reproductive systems and why females go though menstruation.
Key Skills that students should be able to demonstrate at the end of 'Topic'	This is the skills that students will meet for the first time in this topic	Growing seeds to look at variation, using a given method and make observations. How to identify patterns in data and to draw an appropriate graph of the data.
	This is skills that students may have met before but will need to develop	Students may have some experience of drawing charts and graphs and interpreting patterns from them. Students may have experience of planting seeds and observing the changes over time.

The Big Question		How does variation occur?
Key questions that students should be able to answer at the end of the 'Topic'		What is selective breeding?
		How do organisms compete and adapt to their environment?
		What is the difference between genetic and environmental variation?
		How is there variation in seedlings?
		How is data plotted when observing different types of continuous and discontinuous variation?
		Why is biodiversity so important and how have species evolved over time?
		How is puberty different to adolescence?
		What structures are found in the male reproductive system and female reproductive system?
		How do the male and female reproductive organs bring about the fertilisation of the egg?
		What is gestation and how long is it in humans?
		What are the stages of the menstrual cycle and what methods of contraception are there to prevent pregnancy?
