# 95+Olympiad

This is a new course for 2024. I have designed this course to meet the needs of the increasing number of high-achieving students who are completing the year 11 physics course in year 9 or 10, whose goal is to obtain a mark of 95+ in HSC physics.

The aim of the 95+Olympiad course is to offer an alternative option for high achieving students that is more enjoyable and challenging as well asmore likely to result in a higher HSC markthan simply completing the same HSC course twice.

The thinking underlying the course is that there are three components to performing at the highest level in HSC physics (as discussed in on the HSC course page):

- developing the strongest possible conceptual understanding of the physics in the course,
- mastering “working scientifically” skills, and
- perfecting students’ interpretation and written responses to HSC exam questions.

The 95+Olympiad course will focus on developing a deep conceptual understanding of physics in the HSC syllabus (and beyond) on a schedule that suits students who are in year 11 at school.

Polishing written extended response exam answers and memorising fine details can then recieve students’ undivided attention in the second ‘HSC physics’ year, when they have already mastered the physics required to complete all conceptual, calculation based and working scientifically questions in the HSC.

**The “Olympiad” part of the course refers to the fact that students will:**

- complete extension questions on year 11 content at a level that will prepare students to sit the Australian Physics Olympiad exam in August (as well as ensuring that they are extremely well-prepared for their year 11 physics exams at school).
- complete some additional topics (pressure and buoyancy, ideal gases, Bernoulli’s equation, Hooke’s law, simple harmonic motion and rotational motion and torque) that prepare students well for the Physics Olympiad exam in August.
**While these topics are not in the HSC**(almost)*Physics*syllabus, they are**all part of the mechanics section of the Ext 1 and Ext 2 Maths syllabus.** - become more
in using tools such as Newton’s laws, conservation of momentum and conservation of energy in novel and challenging contexts.**fluent and confident** - conduct more sophisticated experimental work than in the year 11 and HSC courses, at a level that will prepare students well for the August Olympiad exam, the Physics Olympiad Summer School, as well as for “working scientifically” assessments at school.
- Students who wish to enter the
**US Physics Bowl**competition in week 9 of term 1 can do so, with exam supervision provided.

The underlyingphysics contentof the HSC physics syllabus is covered in the 95+Olympiad course, at a greater depth than I have time to teach it in the standard HSC course.

*It is important to note that this course teaches HSC physics and additional topics at a higher level than the HSC syllabus. If students do not wish to cover any additional content beyond the HSC syllabus then the HSC physics course will be the best choice.*

**Topics have been arranged so that it is possible for year 11 students to complete this more advanced course simultaneously with the year 11 physics course. **It is recommended that younger students complete the year 11 course first.

It is anticipated that a new HSC class will run in 2025 specifically for students who have completed the 95+Olympiad course.

# Overview of the course

The overview below simply lists topics covered. Practical work is embedded throughout the course and most lessons will involve some hands-on, demonstration or practical component. Students in the course will be assisted to develop their working scientifically skills to a level commensurate with that required for the Physics Olympiad Summer School, ensuring that their skills exceed those required for HSC physics.

Term 1 of the 95+Olympiad course contains extension material for mod 5. The physics content of modules 7 & 8 of the HSC (and extension material on these topics) are covered in terms 2, 3 & 4 of the 95+Olympiad course.

Calculus based extension of Module 6 (Electromagnetism) is covered in the advanced Olympiad course (together with other calculus based extensions of material in the 95+Olympiad course).

Note: Prac work relevant to the topic under study is still a feature of the first hour of the class. The second (optional) hour consists of a series of more substantial pracs suitable for students who wish to hone their practical skills to the level of the Physics Summer School. See the page on the Advanced Olympiad course for information on the pracs in the second hour.
