Devizes School Learning & Education

KS3 Science

Science students in Years 7 and 8 at Devizes School will develop a deeper understanding of a range of scientific ideas in the subject disciplines of biology, chemistry and physics. Students should begin to see the connections between these subject areas and become aware of some of the big ideas underpinning scientific knowledge and understanding.

Students should understand that science is about working objectively, modifying explanations to take account of new evidence and ideas and subjecting results to peer review. Students should decide on the appropriate type of scientific enquiry to undertake to answer their own questions and develop a deeper understanding of factors to be considered when collecting, recording and processing data. They should evaluate their results and identify further questions arising from them.

Students should develop their use of scientific vocabulary, including the use of scientific nomenclature and units and mathematical representations.

Practical Skills

Through all three disciplines students will be able to plan, carry out and record data during a number of science investigations. They will be confident and accurate when drawing graphs and reaching conclusions. They will also develop their evaluation skills. All of these will be vital when students move onto Key Stage 4 study, especially when conducting core GCSE practicals. More able students will be able to identify further questions arising from their results.

A good Devizes science student will work collaboratively with their team and be able to organise their apparatus and work accordingly.

Subject content

Science students in Years 7 and 8 will gain a deeper knowledge and understanding of the key concepts. This will lead to students having a good foundation for further study of topics at
