1. Life Science · Obtain, evaluate, and communicate information from multiple sources to explain the theory of evolution of living organisms through inherited characteristics.

1. Fossils as Evidence: Analyse and interpret data from fossils to provide evidence of organisms and environments that existed long ago
2. How animals adapt to environments: Identify how animals and plants are adapted to suit their environment and understand that adaptation may lead to evolution over time
3. How Natural Selection Works: Explain natural selection as the mechanism of evolution: heritable variation + competition for resources + differential survival and reproduction = change in allele frequency over generations

2. Life Science · Obtain, evaluate, and communicate information to examine the interdependence of organisms with one another and their environments.

1. Ocean Ecosystems: Understand ocean ecosystems as interconnected systems where living things (producers, consumers, decomposers) and non-living factors (temperature, salinity, light, currents) all interact, and that changes to one part affect the whole system
2. Food Webs & Interdependence: Construct and interpret food webs showing the interdependence of organisms in an ecosystem, explaining how a change in one population affects others

3. Life Science · Obtain, evaluate, and communicate information to explain how organisms reproduce either sexually or asexually and transfer genetic information to determine the traits of their offspring

1. Human Reproduction: Describe the structure and function of the male and female human reproductive systems, and explain the processes of fertilisation, gestation, and birth including the role of the placenta
2. Variation in Species: Explain variation within and between species, distinguishing between continuous variation (e.g. height) and discontinuous variation (e.g. blood group), and between genetic and environmental causes

4. Life Science · Obtain, evaluate, and communicate information to describe how cell structures, cells, tissues, organs, and organ systems interact to maintain the basic needs of organisms.

1. Cells to Organ Systems: Describe the hierarchical organisation of multicellular organisms: cells → tissues → organs → organ systems → organism
2. Cells Under the Microscope: Understand that all living organisms are made of cells and use a light microscope to observe, interpret, and record cell structure
3. Parts of Plant and Animal Cells: Describe the functions of the main components of plant and animal cells: cell wall, cell membrane, cytoplasm, nucleus, vacuole, mitochondria, ribosomes, and chloroplasts

5. Life Science · Obtain, evaluate, and communicate information to investigate the diversity of living organisms and how they can be compared scientifically.

1. Classifying Organisms: Describe how living things are classified into broad groups (micro-organisms, plants, animals) according to common observable characteristics, similarities, and differences
