Overview:

KS3 Science will provide a foundation for the students at The Petchey Academy to understand the world around them through the teaching of Biology, Chemistry and Physics. Students are taught essential aspects of the knowledge, methods, processes and uses of science. This foundation of key knowledge and concepts aims to encourage our students to recognise the power and importance of rational explanation and develop their excitement and critical curiosity about the world around us. They are encouraged to understand how science can be used to explain what is occurring, predict how things will behave, and analyse the causes.

 

Year 7 Outline:

Students will study a number of Biology, Chemistry and Physics topics which will build on their prior learning at KS2 and challenge their understanding of the world around them. In Biology, students will study: cells, microbes and disease; the skeletal system; photosynthesis; feeding relationships; balanced diet and digestion; and adaptations and variation. Chemistry units will include: atoms, elements, compounds and mixtures; separating mixtures; particle theory; and simple chemical reactions. Physics units comprise of: forces, solar system, mass and weight; and energy. Furthermore, throughout these topics, students will ‘work scientifically’ in order to understand that science is about working objectively, modifying their explanations to take account of new evidence. Pupils will decide on the appropriate type of scientific enquiry to undertake to answer their own questions and develop a deeper understanding of factors to be taken into account when collecting, recording and processing data. They will evaluate their results and identify further questions arising from them. Therefore, students will have a greater understanding of how scientific ideas have developed historically to reflecting modern developments in science.

Year 8 Outline:

Students build on their knowledge developed in Year 7 to gain sound conceptual understanding of the KS3 National Curriculum. In addition to continuing to ‘work scientifically’, students study further Biology, Chemistry and Physics content. In Biology this includes: reproduction; respiration; smoking and drugs; and inheritance, selection and DNA. In Chemistry, students cover: acids and alkalis; the rock cycle; and patterns of reactivity. Finally, in Physics student cover the topics: sound and light; circuits and electricity; distance, speed and time; magnetism; and pressure and moments.
