The unit builds on unit 8D 'Ecological relationships' and unit 9C 'Plants and photosynthesis'.
It relates to unit 9A 'Inheritance and selection', which considers genetic approaches to improving productivity on farms, and to unit 9G 'Environmental chemistry', in which the importance of air and water quality is considered.
This unit provides opportunities to revisit and revise topics met in other units in years 7 and 8. With some pupils, teachers may wish to consolidate the earlier work, to concentrate on some of the new topics, extending activities, and with others, to spend more time on revision of previous work.
There are opportunities for links with citizenship in the teaching of food production issues. This unit relates to unit 8E(i) 'Producing batches (food)' and unit 9A(i) 'Selecting materials (food)' in the design and technology scheme of work, and to unit 14 'Can the earth cope? Ecosystems, population and resources' in the geography scheme of work.
This unit provides the foundation for work in key stage 4 on the impact of humans on the environment, the management of food-production systems and the importance of sustainable development.
