This unit draws on ideas developed in the key stage 2 programme of study. It builds on
unit 4B 'Habitats' and
unit 6A 'Interdependence and adaptation' in the key stage 2 scheme of work.
Together, this unit and
unit 6A 'Interdependence and adaptation' in the key stage 2 scheme of work could be used as a bridging unit.
The unit provides a foundation for unit 8D 'Ecological relationships' and for unit 9A 'Inheritance and selection'.
The energy transfer ideas of unit 7I 'Energy resources' are used in considering feeding relationships between organisms. If this unit is covered before unit 7I 'Energy resources', then the treatment can be restricted to using the label 'energy' for what is transferred. If unit 7I 'Energy resources' is covered first, then links can be made to the burning of fuels and foods and the Sun as the energy resource for plants.
There are opportunities for pupils to make presentations about, and take measurements in, the environment. This links with unit 3 'Processing text and images' and unit 7 'Measuring physical data' in the ICT scheme of work.
