Science A-Level - Physics
Our students follow a content-led approach. This is a flexible approach where the specification is divided into topics, each covering different key concepts of physics. As our learners progress through the course they will build on their knowledge of the laws of Physics, applying their understanding to solve problems on topics ranging from sub-atomic particles to the entire universe as well as cover the Practical Endorsement which develops practical skills.
Our learners are taught
To develop essential knowledge and understanding of different areas of the subject and how they relate to each other
To develop and demonstrate a deep appreciation of the skills, knowledge and understanding of scientific methods
To develop competence and confidence in a variety of practical, mathematical and problem solving skills
To develop their interest in and enthusiasm for the subject, including developing an interest in further study and careers associated with the subject
To understand how society makes decisions about scientific issues and how the sciences contribute to the success of the economy and society.
The course enables our students to demonstrate and apply the knowledge, understanding and skills for each of the topics, which cover fundamental areas of physics, such as mechanics, materials, electrical circuits, quantum physics and waves

What Will I Study?
We study the OCR Physics A specification of study. It is a linear qualification, which is assessed with 3 examinations at the end of year 13. In addition, they will be expected to analyse, interpret and evaluate a range of scientific information, ideas and evidence using their knowledge, understanding and skills.

How Will I Be Assessed?
Low stakes testing at the start of each lesson allows staff to monitor the ability of students to recall key facts and definitions. Summary questions are set regularly for home learning in order to continually monitor student understanding.
At the end of each topic, students will have an assessment consisting of past exam questions in order to assess their progress.
Internal Exams are completed in June/July of Y12 and again in January of Y13.
All content is examined in three external exam papers in May/June of Y13.
Other Science Experiences
Year 12 students have the opportunity to get involved in the Engineering Excellence scheme, which involves working with local engineering companies in order to design and build something to solve a particular problem. Students then present their ideas and are judged by a judging panel and other teams.
STEM ambassadors come in from the local hospital in order to show students some of their imaging equipment and technology.
