# Physics

**Introduction**

The Physics Department is one of the three limbs of the Science Faculty. We provides courses in physics to Forms 5, 6 and 7. The courses run naturally on from Form 3 and 4 science courses.

Physics is an essential area of knowledge for boys looking to study engineering, chemistry, oceanography, seismology, astronomy and many more. Physics teaches boys how the building blocks of the universe work, and allows our students to leave Auckland Grammar School with the potential to make huge technological advances.

**Physics Tournament**

Auckland Grammar School has had recent success in the New Zealand Young Physicists tournament. The Schools challenge each other to present their solution to one of the 7 open-ended problems set by an international committee of physicists.

*Form 5 (Pre-Q):*

**Pre-requisites:** A background in Form 4 Science is assumed and an ability in Mathematics is an advantage.

**Course description/aims: **Physics is the branch of science concerned with the nature and properties of matter and energy. The subject matter of Physics includes mechanics, heat, light and other electromagnetic radiation, sound, electricity, magnetism, and the structure of atoms. It is the basis for most of the modern advances in technology, electronics, computers, etc.

Candidates who take Physics in Form 5 and do well can continue Physics study through Cambridge Assessment International at AS and A Level or through NCEA Level 2 and Level 3 Physics.

**Methods of assessment: ** School Examinations:

*Internal Assessment:* Regular formative assessment of both theoretical and practical work throughout the course. Students sit School examinations 1 x 1 hour in Term 1 , 1 x 2 hour in Term 2 and a final three-hour examination at the end of the course.

The structure of the examinations will include a multiple choice paper, short answer theoretical questions and alternative to practical data analysis and experimental design questions.

*External Assessment:*The Pre-Q course does not have an external examination. All examinations are set and marked by the School.
