This unit aligns with the AQA Trilogy science specification, building on prior knowledge while integrating substantive and disciplinary knowledge. Prior learning is reinforced through scaffolding and prompts to support all students. Each lesson incorporates retrieval practice such as quizzes, concept mapping, and flashback tasks.
This unit builds on key concepts introduced at KS3, reinforcing students' understanding of magnetism and its applications. They will recall that magnets have north and south poles, with like poles repelling and opposite poles attracting. Magnetic fields, which show the area of influence around a magnet, can be visualised using iron filings or a compass. The Earth's magnetic field is also reinforced as an example of a large-scale magnetic influence, crucial for navigation.
Expanding on this foundation, students will explore electromagnetism, learning that an electric current passing through a wire generates a magnetic field. The strength of an electromagnet can be controlled by adjusting the number of coils, the current, or by adding an iron core. This principle is essential to understanding the motor effect, where a current-carrying wire placed in a magnetic field experiences a force. Using Fleming’s left-hand rule, higher tier students can predict the direction of this force, which is fundamental to electric motors.
To strengthen these industry connections, we have collaborated with Rolls Royce Submarines, whose experts contribute to this unit. Their work in naval engineering and submarine technology relies on precise calculations of forces, acceleration, and momentum to ensure the safety and efficiency of underwater vessels. By integrating expertise from RR Submarines, students can see first-hand how the principles they learn in the classroom are applied in cutting-edge engineering fields.
This unit equips students with both the knowledge and skills necessary to succeed in GCSE Science, while also inspiring them to consider careers in physics, engineering, and beyond. For those interested in future opportunities, our careers zone provides insights into real-world applications and job prospects in industries where expertise in forces and motion is essential.
