New PI Resources. Vicphys News 5/T3/19

The Perimeter Institute has just released some new Resources that will fit nicely with the Fields Area of Study and another that addresses Relativity, Light as a particle and Charges in electric and magnetic fields.  Their quality material is always worth considering.

Also if you wish to offer a workshop at next year’s Physics Teachers’ Conference, you have until next week to register the details.

The next meeting of the Vicphysics Teachers’ Network will be on Thursday, 19th September 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)

1. New Resources from Perimeter Institute
The Perimeter Institute continues to produce high quality educational material that is free to download.  Their latest releases are:

  • Contemporary Physics: Students consider the challenges of space travel and learn about gravity assist manoeuvres and magnetic accelerators. Conservation of energy and the motion of charged particles in magnetic fields are applied as students examine how particle detectors work. Relativistic effects, such as time dilation and length contraction, are explored using hands-on activities. The diffraction of light is used to introduce Heisenberg’s uncertainty principle, which is also the topic of the engaging, accompanying video. The final activity combines Bohr’s quantum hypothesis with the de Broglie wave relation to provide an explanation for discrete energy levels
  • Fields is focused on establishing the reality of electric, magnetic, and gravitational fields. Activities begin with an exploration of the nature of fields and the models that describe them. Students develop a physical model for electric fields and then test it using LEDs. They construct mathematical models that describe electric and magnetic fields and compare these to Maxwell’s equations. Students further explore the reality of fields as they investigate how auroras form. The nature of the gravitational field—as understood by Einstein—is applied to the orbit of Mercury to provide a model for orbital precession. The final activity is a design challenge that introduces students to magnetohydrodynamic propulsion.

2.  Physics Competitions entries are due early next term
Vicphysics runs three competitions:

3. Tutoring positions
Vicphysics is regularly approached by teachers or parents seeking a physics tutor.
A tutor is sought for a Year 11 student in St Kilda.  If you are interested, please email Vicphysics and contact details will be passed on.

4. 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.  Several schools placed notices.
The web page also lists the Government schools seeking a physics teachers, currently there are five.
The webpage also has a link on how schools can register a position and also lodge a payment for the service.

5. Reminder: Offering a workshop at the Physics Teachers’ Conference
The chance to offer a workshop at next year’s Physics Teachers Conference closes on 30th September
The conference will be on Friday, 14th February at La Trobe University.  To register, click here

8.   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.

Cosmic clash over Hubble constant shows no sign of abating

A new way to measure absolute distances in the universe has allowed scientists to work out a new value for the Hubble constant, which tells us how quickly our local universe is expanding. The latest expansion rate is consistent with other direct measures obtained from relatively nearby space, but in conflict with others that rely on the universe-wide spatial features of primordial radiation. This disparity has become more pronounced in recent years and suggests that our current understanding of cosmic evolution may need an overhaul.

Healthcare can worsen global climate crisis
If the global healthcare sector were a country, it would be the fifth-largest greenhouse gas (GHG) emitter on the planet, according to a new report. Its authors, who argue for zero carbon emissions, say it is the first ever estimate of healthcare’s global climate footprint.
While fossil-fuel burning is responsible for more than half of the footprint, the report says there are several other causes, including the gases used to ensure that patients undergoing surgery feel no pain.

Ready, Set, Bake – Physics of Baking
Baking is like a scientific experiment, combining the reactions of chemistry, the processes of biology and the laws of physics. Rahul Mandal, a metrology researcher by training, talks about how his scientific thinking helped him become a baker and win The Great British Bake Off in 2018
The article also has a link to Robert Crease’s article on the Physics of Bread.
