Science at key stage 3    (Year 8)

Unit 8D: Ecological relationships

QCA

Expectations

At the end of this unit

in terms of scientific enquiry

most pupils will:
suggest what data should be collected to investigate a habitat and choose appropriate apparatus and techniques to make measurements and observations; use a sampling technique to collect data to compare populations in habitats; use ICT to collect, store and present information in a variety of ways

some pupils will not have made so much progress and will: collect data to investigate a question about a habitat using appropriate apparatus and techniques; use ICT to collect, store and present information

some pupils will have progressed further and will: plan how to collect reliable data, taking into account the fact that variables cannot readily be controlled

in terms of life processes and living things

most pupils will: classify some plant specimens into the main taxonomic groups of plants; identify and name organisms found in a particular habitat and describe how they are adapted to the environmental conditions, explaining how the adaptations help survival; relate the abundance and distribution of organisms to the resources available within a habitat and begin to represent this using pyramids of numbers

some pupils will not have made so much progress and will: name some organisms found in a habitat and describe how they are adapted to environmental conditions; recognise that the abundance and distribution of organisms is different in different habitats

some pupils will have progressed further and will: explain how pyramids of numbers represent feeding relationships in a habitat
