1. Network Meeting: Sharing ideas on 'Managing Multiple Options in Unit 2', 6pm, Tuesday, 13th October, University High School

The Vicphysics Teachers' Network would like to live up to its name by putting aside the second hour of its monthly meeting for teachers to share ideas about teaching different aspects of next year's Year 11 course. The next meeting on 13th October will consider 'Managing Multiple Options'. The format will be informal with a focus on small group discussion with groups addressing different aspects of course planning and lesson preparation.

Up until a couple a years ago, students did four Detailed Studies over the two years. The introduction of Detailed Studies coincided with an increase in the proportion of Year 11 physics staying on to do Year 12 physics, both boys and girls, which has continue to grow. Currently the retention rate is about 80%. The Vicphysics Committee thinks there is a causal connection. The Detailed Studies enriched and broadened the students' experience of physics.

Next year, physics students will do only one option over the two years. A way to maintain the enriching experience is to offer a few options in the classroom at the one time, so that students get a sense, either informally or formally of the breadth of physics and what opportunities it offers.

More particularly, most teachers who have been teaching for a few years will have already taught four of the 12 options in next year's Unit 2.

The discussions will start at 6pm and finish at 7pm.

If you wish to attend, please register by emailing Vicphysics at vicphys@ with subject 'Registration: Networking', so that the event can be effectively planned, but also because the space will put a limit on the numbers.

2. Vicphysics Website Redesign: Preparing for 2016

The home page for the Vicphysics website has been changed to reflect the structure of the Study Design in 2016. There are now more categories down the side.

The 'Teachers' category now has sub-categories for: 'Unit 1 in 2016, 'Unit 2 in 2016', 'Units 3 & 4 in 2016', which then show links to webpages for each Area of Study and for each Option. Other sub-categories in this section are 'General Resources' for a further seven webpages, and 'Revision and Exam Solutions', 'Course planning' and 'Equipment'.

Please check it out and suggest further improvements.

3. Physics and Video Photo Contests: Entries are due.

Several entries have already been received. The official closing date for both events is today, the first day of Term 4.

4. US Websites on teaching strategies and curriculum materials

a) The Diagnoser, , "is a set of diagnostic instructional tools for middle and high school teachers and students. Resources in this project have been developed and tested by teachers and are based on research into the teaching and learning of maths and science. They have designed sets of questions as formative assessments (e.g., assessments to inform learning and instruction rather than assign scores.) Students receive feedback on their thinking as they work through their assignment. Teachers can access reports on students' thinking related to the assigned content."

To access the material you need to register and set up a username and password. You can set up your classes and give each student a unique username and password and assign specific topics. There is no cost.

The areas covered include Mechanics, Waves and Thermal physics with several topics in each, but mainly at Year 10 and Year 11 level. For each topic there is a section on:

• Learning goals: expectation of what the students should understand,

• Facet cluster: a detailed breakdown of the common misconceptions,

• Eliciting questions: designed to open up many of the existing ideas among the students in the class, with typical incorrect responses and advise on how to manage them,

• Development lessons: Lessons that will challenge problems exposed by the questions and also build on strengths in students' thinking,

• Diagnoser question sets: The questions are designed to elicit different misconceptions in student thinking. The program provides feedback to students to assist them in monitoring their own learning. After students have completed a set of questions, teachers are able to view the misconceptions diagnosed for each question for each student.

• Prescriptive activities: These activities may be assigned to individual students or to the whole class. They are designed to target specific problematic ideas diagnosed in the previous section.

b) The Physics Aviary, , is a US website by teacher Frank McCulley. It is designed to assist students and has a range of activities including:

• Lab simulations which were written as a complement to real practical activities. They cover the full range of physics topics,

• 'Tools' is mainly advice on graphing,

• 'Homework problems',

• 'Games' has several basic skill based games and

• 'Review questions'.

The programs are written in HTML 5 to work on computers, tablets, phones and other handheld devices.

c) Exploring Physics, , is a commercial online product for tablets. "The Exploring Physics App is an interactive inquiry- and modeling-based conceptual physics curriculum. It combines hands-on activities with a discussion-based pedagogy where students construct mental models of scientific concepts. The app is constructed so that students input their ideas into the app in text, drawings, and graphs – so the app works as a workbook, lab book and textbook all in one".

There will eventually be 9 units that will be released over the next 18 months, with some already available. An individual unit can be purchased for US$12 per student.

d) APlus Physics is a compilation of Youtube videos and other resources. It currently has 858 videos grouped under 18 different topics.

Items supplied by Barbara McKinnon and Oliver Lovell.

5. Highlights from the UK Physics Education Journal - Free download

7. Forthcoming events for Students and General Public *

a) New Windows into the Universe: From Cosmic Dawn to Today, 6:30pm, 9th October, Swinburne University

Speaker: Assoc Prof Kim-Vy Tran, Texas A&M University.

Abstract: Since Galileo's time, our ability to study the universe has been driven by our ability to collect light from distant objects. Due to tremendous technological advances in the last few decades, we can now study the most distant galaxies known in the universe. In addition to seeing fainter objects at higher resolution, we can also view the universe at many different wavelengths ranging from gamma rays to radio waves. I highlight the major advances that have been made with, e.g. the Keck telescopes and Hubble Space Telescope, and discuss why we need to continue pushing our limits by developing and building new observatories like the Giant Magellan Telescope.

b) Tune into the skies: how to do cosmology in the radio, 6:30pm, 23rd October, Swinburne University

Speaker: Dr Laura Wolz, University of Melbourne.

Abstract: Radio telescopes have made numerous appearances in media and films due to their huge, mechanical appearances contrasting with the natural background. The gigantic size of the dishes are essential for observing cosmic objects in high resolution following the basic rule: the longer the wavelength, the bigger the dish. The construction efforts are worthwhile because radio waves can pass our atmosphere nearly unobscured and thus allow us to view the Universe whether it is sunny or cloudy. But what are we looking at? Every galaxy emits a wide range of radio waves, including our own Milky Way, allowing us to measure the positions of the galaxies in space. Radio waves also carry information about the interior of galaxies, namely their hydrogen content. Radio telescopes can be used as cartographers to map the cosmic landscape by their hydrogen emission. This allows us to see areas unobtainable through visible light and take a glimpse how the Universe looked when it was less than half of its age. We can use both, galaxy catalogues and cosmic maps, to explore how the Universe evolved to the present state. We can learn how space floated apart after the Big Bang, how gravity pulls structures together and how dark energy is mysteriously speeding up the expansion of the cosmos.

b) Mini PD on Thermodynamics and What is matter? at VYPT, 1st, 2nd December, University High School

The number of teams participating in VYPT have been increasing each year. The greater numbers puts pressure on providing enough judges. As an incentive to encourage teachers to come along to check out the event and to assist with the judging, as part of the day there will be two presentations for such teachers on course planning for the two new Areas of Study in Unit 1: 'Thermodynamics' and 'What is Matter? The presentations will cover: new concepts, practical activities, resources and assessment ideas.

Judging is done by a team of three, with at least one experienced judge. The preparation for judging involves about 45 minutes pre-reading and the task involves assessing students. The same mini PD will be offered on each day.

Dates: Tuesday, 1st and Wednesday, 2nd December

Venue: Elizabeth Blackburn School of Sciences at University High School

To register for the mini-PD and judging VYPT, please email Vicphysics events@ with subject: Registration: Mini PD giving name, school and on which date you wish to attend.

A distinctive feature of our conferences has been the large number of teachers who offer workshops about what they do. These workshops are not only beneficial for other teachers, but they also significantly enhance the curriculum vitae of the presenters and their own personal skills.

Also as with the 2015 conference, this program will include a strand of workshops on teaching the Physics aspects of Yrs 7 - 10 Science. These will be for teachers of Year 7 - 10 Science without a physics background.

If you would like to offer a workshop, either for your fellow physics teachers or on Year 7 - 10 Science, please register the workshop on the STAV website , select Conferences/PD and go down to 'Presenters' and complete the online submission.

The Conference will be on Friday 19th February at Monash University.

9. Physics News from the Web

Items selected from the bulletins of the Institute of Physics (UK) and the American Institute of Physics.

Each item below includes the introductory paragraphs and a web link to the rest of the article.

a) Levitating diamonds could improve motion sensors

b) Earthquakes could be triggered by sound waves that 'fluidize' faults

c) New laser could spot signs of cancer in exhaled breath

a) Levitating diamonds could improve motion sensors



By levitating a tiny, nano-sized diamond using light, physicists in the US and Finland have created a controllable quantum system that has optical, mechanical and spin degrees of freedom. Based on a single "nitrogen vacancy" (NV) defect in the diamond, the system could be used in devices that measure extremely weak forces – or even to create "Schrödinger's cat states".

NV defects occur in diamond when two adjacent carbon atoms are replaced by a nitrogen atom and an empty lattice site. One type of NV (NV–) is of great interest to physicists building quantum devices because its spin state (–1, 0 or +1) can be determined very easily using light. Furthermore, NVs are well isolated from their surroundings, which means that their spin states – unlike those of most other solid-state systems – keep their quantum nature for relatively long times.

b) Earthquakes could be triggered by sound waves that 'fluidize' faults



Earthquakes may be triggered by sound waves that reduce the friction between rocks at a geological fault. That is the conclusion of an international team of researchers that has done laboratory-based experiments that mimic the process. The results support the "acoustic fluidization" theory of earthquake triggering, which seeks to explain the unexpected weakness of some faults. The research could also help to reveal how aftershocks are generated at great distances from the earthquakes that precede them.

c) New laser could spot signs of cancer in exhaled breath



A new type of compact infrared laser promises to make it easier to identify specific molecules at very low concentrations within complex chemical samples. That is the claim of physicists in Germany and Spain, who have created the high-power, ultrashort-pulsed, broadband laser. They add that the device shows particular promise for spotting molecules within exhaled breath that are indicative of certain kinds of disease.

Molecular spectroscopy, or "molecular fingerprinting", involves shining a laser beam spanning a certain portion of the electromagnetic spectrum through a liquid or gas and then comparing the beam before and after it travels through the sample – the specific wavelengths absorbed revealing the composition and structure of molecules within the sample. Most molecular vibrations can be stimulated by mid-infrared radiation (2–25 μm), and therefore laser light covering this part of the spectrum is very useful for molecular fingerprinting.
