Perimeter Institute and 4C Physics

Do you teach 4C physics? The Perimeter Institute of Theoretical Physics is planning to create a resource tied to 4C physics and wants to know what you think would be most useful. You can help out by filling in this brief (3 minute) survey. https://www.surveymonkey.com/r/ZM9YYRT If you don’t teach 4C physics, but know someone who does, please pass this on to them.

The End of Conventional Current

Chris Meyer
President, Ontario Association of Physics Teachers

Time to Let Go
It’s time! Conventional current, the mysterious flow of positively charged particles in current electricity, has outlived its usefulness. This model hinders the development of clear physical understanding and places an additional, unnecessary conceptual burden on all our students. We ought to let the few students who pursue the electrical trades, electrical engineering, or physics deal with this awkward relic. Use electron current in high school. It’s time to let go of the ghosts from our disciplinary past and focus on improving our students’ learning. Read More...

OAPT-OTF Physics Camp is back!!

Exploring Inquiry in Science and Physics
Kingston, July 24-26, 2018

Join James, Roberta and (some surprise presenters!!) for twelve new workshops for physics in grades 9-12. These sessions will include topics such as smart phone apps, gravity assists, modelling particle models and concepts schmoncepts. It will also feature three brand-new resources from the Perimeter Institute of Theoretical Physics on Energy, Waves and Climate Change!

All of the workshops will be fully hands-on and engaging. You will have lots of time to explore the materials and discuss the concepts with other keen teachers like yourself. We will be following a schedule that is quite different from the other OTF camps, but which has worked really well in the past. The first two days will be extra-long so that the last day (Thursday) is just a half-day which will make getting home easier. Because we start bright and early on the Tuesday, we strongly recommend that you ask for the optional accommodation on Monday night.

This camp is fully funded by the OTF and therefore registration is only open to teachers who are part of the OTF. We are sorry that we can’t include private school teachers or teacher candidates.

Registration opens June 1.

Last year, we had more registrants than space — so make sure you sign up early! If you have any questions, feel free to email roberta@tevlin.ca. Please email Roberta after you register, so that she can arrange car pooling and other last minute things.

Check out the agenda for more detailed information.

Hands-On Fields

Roberta Tevlin
Teacher at Danforth CTI, Manager OAPT Newsletter

The concept of fields is fundamental to our modern understanding of physics and the Ontario curriculum dedicates one of the five units in 12U physics to Gravitational, Electric and Magnetic Fields. I have struggled for many years to find ways to make this important but abstract concept more tangible to my students. Here is what I have come up with so far. Read More...

LEDs: An alternative to traditional bulbs

David Gervais
STAO Safety Chair

The traditional incandescent bulbs used for teaching series and parallel circuits are rated for 3 V or 6 V. The problem is that many power supplies can generate 12 to 15 V. As a result, it is common to have many blown bulbs. With several sections teaching this unit, bulbs can quickly become in short supply. Each bulb replacement can cost $1.00 each, and often are included in the general department order at the end of each semester. For those teachers using breadboards, traditional bulbs are also not easily adapted to fit into the small holes. LEDs are a great alternative for many reasons. Read More...
