Vicphysics Teachers' Network Inc.
Dear *|FNAME|*,

The 2019 Physics Teachers' Conference was held last Friday. Some of the presenters and the Chief Assessor, Andrew Hansen, have already provided their workshop material. Videos of the two addresses are also available.

Andrew mentioned at the conference that his report on the 2018 Physics Exam is now on the VCAA website. See the link and related information below.

If you can spare a few minutes to do an on-line evaluation of the workshops, etc that you attended, it willbe really helpful in providing valuable feedback for the presenters.

Also, if you were at the conference and haven't received this newsletter before, you have just been added to its mailing list.  So you will have missed the two earlier newsletters sent out this term.  They can be accessed here.

Chief Assessor's Forum: Andrew could only focus on a small batch of exam questions at the conference.  You can hear the full analysis of how students performed on the whole exam paper at the Forum on Tuesday, 12th March, but you need to book.

And check the update on the Physics Days at Luna Park.


The next meeting of the Vicphysics Teachers' Network will be on Thursday, 7th March at Melbourne Girls' College starting at 5:00pm. Teachers are welcome to these meetings. If you wish to come, please email Vicphysics

Frances Sidari (Pres), Jane Coyle (Vice-Pres), Dan O'Keeffe (Sec) and Terry Tan (Treas)

Vicphysics and the Chief Assessor, Andrew Hansen, would again like to provide teachers with the opportunity to hear about the full exam with an extended opportunity to ask questions and a chance to speak with Andrew.

The Chief Assessor's Forum is a question by question coverage of the students' responses to last year's Physics exam.  The event will also be streamed live.
The forum will start at 5:00pm, with a meal break at 6:30pm, commencing again at 7:15pm.  Dinner will be provided.
Cost: $60 to attend the event, including the meal. $30 to view online.
Venue: The Elizabeth Blackburn School of Sciences at University High School in Story St, Parkville.
Booking: You will need to book through Trybooking, check our website for details.

4.  Report of the 2018 VCE Physics Exam
The VCAA website now has the report of last year's exam.  For the section A multiple choice questions, the report supplies the percentage of students who chose each alternative as well as brief working.  For each of the section B questions, the report gives the percentage of students who were awarded 0 marks, 1 mark, etc. The comment section has brief working and any common errors.  There is no overall summative report.
The Vicphysics website has detailed solutions to assist students when using the paper as revision.  The solutions include a suggested marking scheme as well as additional revision questions that can be asked using the information in the stem of some of the exam questions.
5.    Events for Students and the General Public
a) Friday, 22nd February, Things that go bump in the night: fast radio bursts and the search for life beyond Earth, 6:30pm, Swinburne University
Speaker: Dr Daniel C Price, Centre for Astrophysics and Supercomputing, Swinburne University
Venue: Swinburne University, Hawthorn campus, ATC building, ATC101 (Enter from Burwood Road)
Map: http://www.swinburne.edu.au/media/swinburneeduau/about-swinburne/docs/pdfs/hawthorn-map.pdf
Abstract: Thanks to new, more powerful technology, astronomers can search the skies faster and with more resolution than ever before.  In this public lecture, I will talk about two exciting fields in astronomy: the Search for Extraterrestrial  Intelligence (SETI), and Fast Radio Bursts. The SETI field has been reinvigorated by the 10-year, $100M Breakthrough Listen initiative to search for intelligent life beyond Earth. As a project scientist for Breakthrough Listen, I will introduce the program and detail how we are using new technology to run the most comprehensive search for intelligent life beyond Earth ever undertaken. I will also discuss a mysterious phenomenon known as fast radio bursts: incredibly bright but short-lived signals from distant galaxies, which escaped detection until recently. Could these signals be due to intelligent aliens, or is there an astrophysical explanation? I will give an overview of how a telescope upgrade will help us answer this question, and how Swinburne astronomers will play a leading role. Finally, I will discuss what evidence would convince us that there is indeed life beyond Earth, or that the Universe is ours alone to enjoy.

 The event is for:

  • Teachers beginning their teaching career,
  • Teachers returning to physics teaching and
  • Teachers who have been asked by their school to take a VCE Physics class
 The program will include:
  • Information on course planning, resources, advice of teaching specific topics and suggestions from some of last year's participants after teaching physics for the first time in 2018,
  • Andrew Hansen, Chief Assessor for the Physics exam, from Ringwood Secondary College on Exam advice.

To register please complete the details on this Vicphysics webpage. . It also has  information about last year's program.

7.   Physics from the Web
Items selected from the bulletins of the Institute of Physics (UK).
Each item below includes the introductory paragraphs and a web link to the rest of the article.
 a) The Search for Silicon's Successor

Jon Major assesses how the materials used to make solar photovoltaic cells have evolved from first-generation silicon up through thin films, perovskites and (maybe) beyond.

b) Solar Windows: Seeing through the glass, darkly
Windows that transform solar energy into electricity without plunging the rooms behind them into semi-darkness might sound too good to be true, but new techniques could yet make solar windows a common element in future urban architecture.
Back in 2010 Oxford PV was a small start-up with a big dream: it wanted to pioneer the market in solar windows. The idea of integrating sources of renewable energy directly into the buildings they power promised to transform the electrical grid – perhaps even realizing the goal of making cities carbon neutral on a relatively short timescale – and the company’s founders seemed well placed to turn it into reality. One of them, physicist Henry Snaith, had developed a dye-sensitized solar photovoltaic (PV) cell in his laboratory at the UK’s University of Oxford that was thin enough to be semi-transparent, while maintaining relatively high efficiencies. Using this material to make electricity-generating windows seemed like a logical next step.

c) It's all smoots and garns: Unusual physical units
SI units are a scientist’s best friend, but there are also some unusual scales of measurement available: The stories behind some of the world’s more weird and wonderful units

How much beauty does it take to launch a ship? How much does a male physicist’s beard grow in a second? And what is the optimal length of a lecture? These may not seem like typical phenomena you need to measure, but they’ve nonetheless inspired creative souls to forge new units of measurement.

They are just some of the weird scales that exist in the shadows of the formal SI units and their spin-offs. With the recent redefinition of our beloved kilogram, ampere, kelvin and mole, now is the perfect moment to acknowledge those other units that escape the close scrutiny applied to scientific inquiry.
