Science at key stage 3    (Year 9)

Unit 9M: Investigating scientific questions

QCA

Expectations

At the end of this unit

in terms of scientific enquiry

most pupils will: identify questions that can be tackled through scientific enquiry and identify strategies appropriate to different questions; select and use a suitable strategy for solving a problem, carrying out preliminary work where necessary; decide when it is appropriate to use secondary sources of information and choose appropriate sources; describe the strength of evidence or the quality of the product, in their own and others' enquiries

some pupils will not have made so much progress and will: identify more than one strategy for investigating questions and recognise that secondary sources may sometimes be necessary to obtain information or data; carry out an enquiry using a suitable strategy and recognise that one enquiry might yield stronger evidence or a better product than another

some pupils will have progressed further and will: suggest strategies for tackling different questions and explain why these are appropriate; describe how secondary sources vary in the quality and relevance of the information or data they provide; use their scientific knowledge and understanding to justify and/or challenge their own or others' conclusions and methods, and identify the limitations of the evidence produced from a variety of different enquiries
