Science at key stage 3    (Year 9)

Unit 9A: Inheritance and selection

QCA

Expectations

At the end of this unit

in terms of scientific enquiry

most pupils will: select and make effective use of secondary sources of information about inheritance and selective breeding; plan how to collect, store and use data about a large number of individuals; use ICT to produce graphs and draw conclusions from these; evaluate the strength of evidence in relation to sample size and variation within the sample

some pupils will not have made so much progress and will: select information from secondary sources about inheritance and selective breeding; collect, store and use data about a large number of individuals; use ICT to produce graphs and identify patterns in these

some pupils will have progressed further and will: synthesise information about inheritance and selective breeding and identify limitations in the data assembled; decide whether the data collected about individuals is sufficient for firm conclusions

in terms of life processes and living things

most pupils will: identify some inherited characteristics and describe how some characteristics are influenced by environmental conditions; describe how sexual reproduction results in genetic information being inherited from both parents; identify characteristics in a plant or animal which are desirable in particular circumstances; outline how these characteristics might be passed on; suggest some of the issues to be considered in relation to selective breeding

some pupils will not have made so much progress and will: identify some inherited characteristics and some influenced by environmental conditions; describe sexual reproduction as the joining of two cells; identify some characteristics of an animal or plant which are desirable in particular circumstances

some pupils will have progressed further and will: describe how selective breeding can result in offspring with particular characteristics; recognise that asexual reproduction produces clones
