1.  Solar Cell Challenge: An experimental challenge for Students from Years 7 – 12
The ARC Centre of Excellence in Exciton Science is offering two challenges, one for Years 7 – 9 and one for Years 10 – 12.   ‘Students are doing hands-on science and converting light into electricity!  This challenge gets the students thinking creatively around manipulating experimental variables, producing a scientific product and communicating process and findings through video’.
The Years 7 – 9 challenge offers some free equipment and so should be checked out.
In the Years 10 – 12 challenge, students in teams of 2 – 3 create their own solar cell.  S
tudents will need to ‘apply a range of techniques and create a method to enhance an existing or new simple solar cell.  Students record their journey and show their scientific product in action via 2 – 3 min video, which is judged’.
As the product produced in this Challenge is open, equipment is not provided to teams.  Therefore, there is no cost per team to enter.  However, teams/schools must supply and purchase their own equipment, the total cost of which should come to no less than $50 per team.
Schools can enter up to 6 teams.
Time line:

  • Registrations close       3 April
  • Teacher resources and judging criteria released   6 April 
  • Resource package send out      6 April (week of) 
  • Submissions open       14 April 
  • Submissions close       26 June 
  • Winners announced      Late July

Prizes   For the overall winning teams, their schools will receive a starting grant to initiate a new and/or enhance an existing energy sustainability initiative.  The schools will also receive a researcher visitor to speak to a group of students and/or at an assembly.   Individual student winners will receive a prize pack of goodies depending on the category!

2. The Physics of Olympic Sports: A Perimeter Institute poster
Their popular ‘Science of Sport’ poster has been revamped for the 2020 Olympics. A high resolution pdf can be downloaded from here.  There is no cost.  Also check out their other posters, including their series of  Women in Physics.
They also have classroom activities on the following topics: Astrophysics, Electricity & magnetism, Particle physics, Quantum, Relativity and Waves

3. Seeking a Physics Teacher? Seeking a job?
Last year Vicphysics Teachers’ Network set up a Job Ads page on our website to assist schools in finding a physics teacher, either to be a LSL replacement or to fill an ongoing position or just to cover an extended sick leave.

  • Ballarat and Queen’s Anglican Grammar School is seeking a physics teacher to start in Term 2, closing date: 13th March.
  • There are three Government schools seeking a physics teacher, Baimbridge College, Kurunjang Secondary College and Mount Erin Secondary College.

This webpage is updated every weekend.  The webpage also has a link on how schools can register a position and also lodge a payment for this service.

6.   Physics from the Web
Items selected from the bulletin of the Institute of Physics (UK).
Each item below includes the introductory paragraphs and a web link to the rest of the article.

Nanowire device generates electricity from ambient humidity
Scientists in the US claim to have developed a device that can generate electricity from moisture in the air. The device, based around a thin film of electrically conductive protein nanowires, can produce continuous electrical power for around 20 hr, before self-recharging. The researchers say that such technology could provide clean energy without the restrictions on location and environmental conditions of other renewable energy solutions such as solar cells .

The device consists of a roughly 7 µm thin film of protein nanowires, harvested from the microorganism Geobacter sulfurreducens, deposited on a gold electrode with an area of around 25 mm2. A smaller, roughly 1 mm2, electrode is placed on top of the nanowire film.

Novel photovoltaics generate electrical power from thermal sources
A new type of photovoltaic device can generate useful amounts of electrical power from sources that radiate heat at moderate temperatures. So say researchers at Sandia National Laboratories in the US, who succeeded in recovering power densities between 27–61 
μW/cm2 from thermal sources at 250–400°C. The new energy-harvesting technology might be used on waste heat from nuclear power plants or chemical manufacturing facilities. According to Paul Davids, who led the research effort, it could also aid the development of compact thermal power supplies for deep space probes and other remote applications.

Our universe has anti-matter partner on the other side of the Big Bang, say physicists from Perimeter Institute
Our universe could be the mirror image of an antimatter universe extending backwards in time before the Big Bang. So claim physicists in Canada, who have devised a new cosmological model positing the existence of an “antiuniverse” which, paired to our own, preserves a fundamental rule of physics called CPT symmetry. The researchers still need to work out many details of their theory, but they say it naturally explains the existence of dark matter.
