A Ghostly Hologram

Saara Naudts, Physics Teacher (Peel District School Board)
saara.naudts@icloud.com

When I was looking at a quick and fun activity to spark students’ interest in optics, I came across several "how to turn your smartphone into a 3D hologram" videos. It shows how when you place a small, clear pyramid on your phone's screen playing a specially created “hologram” video, the video appears floating above your phone within the pyramid.

Intrigued, I wondered if this was just another internet hoax as I couldn't understand how a hologram can be created using a smartphone, but a colleague overheard my questioning and affirmed she heard from a teacher's friend's friend that this works! Hmmm... I wasn't really oozing confidence after that answer, so I tried building one myself. Read More...

Demonstrating Diversity in Science

Sara Cormier, Michelle Lee, Sarah Naudts, Roberta Tevlin

The four of us, like many of you, are concerned about how slowly the world of physics is moving towards diversity. Over the summer we put together some resources to make it easier to demonstrate to our students that there is a place for everyone in physics. Read More...

Improv-PHYS-ation Logo

We would all like to build classroom communities where our students flourish. We would like our students to develop their curiosity, creativity, critical thinking, persistence and resourcefulness. As science educators, what can we learn from the arts?

In improvisational theatre (“improv”), an “ensemble” is a group of people that work together cohesively and support each other to co-create a performance, recognizing and building upon each other’s individuality and contributions. For social learners, participation in an ensemble can foster our best learning. Can we create ensembles in our classrooms? Read More...

Rosalind Franklin, DNA and the Interference of Light

Roberta Tevlin, Editor OAPT Newsletter, Teacher at Danforth CTI
Roberta@tevlin.ca

We need to incorporate more diverse examples of scientists in our courses. Sara Cormier (Physics Instructor at McMaster University) and I are trying to develop resources that will help teachers to do this. (If you would like to be a part of this — please send me an email!)

I started to compile a data base of good examples when I found myself completely distracted by the work of Rosalind Franklin. Her work on the X-ray crystallography of DNA fits perfectly into a lesson about the interference of light! As well as showcasing an important female scientist, an examination of her work can deepen students’ understanding of interference patterns and it highlights a very important connection between biology, chemistry and physics. I found a couple of short videos and a really simple, cheap demo that shows why the interference pattern formed by DNA provides clear evidence of its helical structure! Read More...

As, for, of… How to effectively assess collaborative learning

Vjera Miović, Teacher at Silverthorn CI, OAPT Newsletter Volunteer
vjera.miovic@tdsb.on.ca

Imagine a test (and yes, it’s for marks!) during which everyone gets to see everyone else’s work, students can change, correct and update their product for a better mark, they consult each other and talk freely, and they even google information they need to solve a problem. What would you think of this assessment method if it was a physics class, or a math class? Wouldn’t that be considered cheating? And yet, my grade 9 tech students get evaluated exclusively this way.

The Hole Truth: Why black holes aren’t what you’ve probably been told they are!

Philip Freeman, teacher at Richmond Secondary School (Richmond BC), Executive member BCAPT
freeman@sphericalcows.net

Black holes are big news these days. Unfortunately a significant number of statements in the press are not only mistaken but wrong in ways that obscure the truly interesting and important things we know about black holes. This article hopes to clarify a number of points about what black holes are and are not. Read More...

The Story of Physics: Storytelling for High School Physics Teaching

Brian Lim, Teacher Rosedale Heights School of the Arts, Toronto
Brian.lim@tdsb.on.ca

“In the beginning…”

So starts one of the most famous and influential stories in Western civilization. Neil Degrasse Tyson continues the narrative this way:

“...sometime between 12 and 16 billion years ago, all the space and all the matter and all the energy of the known universe was contained in a volume less than one-trillionth the size of the point of a pin. Conditions were so hot, the basic forces of nature that collectively describe the universe were unified. For reasons unknown, this sub-pin-pint-size cosmos began to expand…” [1] Read More...

Controlled Experiments with Three Factors in SPH4C Grade 12 College Physics

Tim McCarthy, Teacher, St. Ignatius of Loyola Catholic Secondary School
mccarthyt@hcdsb.org

Controlled experiments with three factors are a great way for physics students to practice identifying and testing factors that may affect a situation. They provide an excellent opportunity to practice the Scientific Investigation Skills found in Strand A. The students are provided with a situation, brainstorm possible factors that may affect the situation, reduce the list of factors to three that can be tested in the physics lab, develop hypotheses, design procedures to test the factors, test the factors, analyze the data, perform experimental error analysis, and draw conclusions on the effects the three factors have had on the original situation.

My struggle has been to find situations that easily fit this format and that also match the curriculum specific expectations. I have created one three-factor controlled experiment for each of the six units in my 12C physics course. The three-factor experiment in the first unit is used as assessment for learning (formative) to teach the students how to do a controlled experiment. The remaining five experiments are used as assessment of learning (summative). Simulations are used for some experiments as I do not have the necessary equipment to perform all them in the lab.

Marking Tests Faster

Robert Prior, teacher at Agincourt CI
robert.prior@tdsb.on.ca

Many of us find marking tests a necessary chore. It has to be done, but it’s drudgery. This article describes how I use an app and the Ontario Achievement Charts to mark tests 2-3 times faster, as well as analyze the results. Read More...

Intersection Traffic Signals: Coding to Control Series and Parallel Circuits in Grade 12 College Physics and Grade 11 University Physics

Tim McCarthy, Teacher, St. Ignatius of Loyola Catholic Secondary School, Oakville, ON
mccarthyt@hcdsb.org

Coding is an important skill for physics students to learn. Grade 12 College and Grade 11 University physics students must build series and parallel circuits, so why not use coding to control them and model an everyday, real-world situation? This can be done by first using TinkerCAD simulations, followed by construction of the simulation using real components; Arduino UNO R3 microcontroller boards, breadboards, LEDs, resistors and wires. Students have a high level of satisfaction as they complete a task that is brand new to most and learn skills that they are likely to need in their post-secondary education. Read More...

Light ’Em Up!!! – Electric Greeting Cards for the Grade 9 Electricity unit

Andrew Moffat, Teacher Bishop Strachan School
amoffat@bss.on.ca

Students often struggle with the “Physics” unit in grade 9 Science — electricity. This can lead to a negative association with Physics and fewer students taking grade 11 and 12 Physics. At our school we have tried to make the electricity unit (and specifically the idea of circuits) more fun and engaging by having students create an electric greeting card consisting of LEDs and a battery. This can be done for around $2 per student. Read More...

Event Horizon Telescope Captures First-ever Image of a Black Hole

Damian Pope, PhD, Senior Manager Scientific Outreach, Perimeter Institute for Theoretical Physics
dpope@perimeterinstitute.ca

What is the Event Horizon Telescope?
The Event Horizon Telescope (EHT) is a network of radio telescopes spread across the globe. By pooling data from each instrument, it achieves the same effective resolution as a dish the size of the entire planet!

What did it discover?
The EHT collaboration has just released the first event-horizon-scale images of M87*, a supermassive black hole at the centre of galaxy M87. The image shows an asymmetric ring of light surrounding a circular shadow. The ring of light is not the accretion disk, it is the footprint of the relativistic jet created by M87*. The asymmetry is evidence for the direction of the black hole’s spin. The size of the shadow reveals the mass of M87* which can then be used to calculate the radius of the event horizon. Note, the shadow is not the event horizon. Read More...

Making Waves — a resource for exploring interference concepts

Philip Freeman, teacher at Richmond Secondary School (Richmond BC), Executive member BCAPT
freeman@sphericalcows.net

Waves are the source of many of the most beautiful and fascinating phenomena in physics, and a key idea underlying our deepest models of reality. The signature feature of waves is interference, and we frequently refer to interference effects to justify our claims about the wave nature of light (and electrons, and buckyballs, and…). This resource provides a new way to model waves that allows a more direct and intuition-building experience of interference. Read More...

Mari-Ann Goettsch, teacher at Georgetown DHS
goettschm@hdsb.ca

Over the past couple of decades there has been a dramatic decline in students’ abilities to build and solve hands-on challenges. They are well versed in virtual reality but they don’t have much experience in how to work with materials. This is a shame. They are at a disadvantage when learning physics concepts and they will have huge problems with large projects like trebuchets or Rube-Goldberg machines. In this article we will describe a number of very short hands-on projects that provide opportunities to build stuff using cheap materials. Read More...

Why Don’t Students Improve? Part II

Chris Meyer, President, Ontario Association of Physics Teachers; Hybrid Teacher-Coach, TDSB
Christopher.meyer@tdsb.on.ca

So you put all that time and effort into carefully marking the test, including helpful descriptive feedback, and what happens? The student grabs the test, looks at the mark, and tosses it away. Us teachers understand that a test is an important learning experience, but this common student behaviour shows students think otherwise: a test is just a chance for us to deny them marks or sort out the strong students from the weak (a ranking they already know). From that viewpoint, why should a student do anything more than look at the mark and/or complain? And why bother to look at the feedback and make any effort to improve? Read More...

Why Don’t Students Improve? Part I

Chris Meyer, President, Ontario Association of Physics Teachers; Hybrid Teacher-Coach, TDSB
Christopher.meyer@tdsb.on.ca

For years it drove me crazy. I would remind students again and again about common mistakes and important details; I would make a grand production of it. But, they would make the same errors again and again. Why? A big part of the answer is this: my students never practiced assessing the quality of their own work and making improvements. This is the idea behind metacognition: the ability to monitor the process and quality of one’s own thinking and work. If we don’t train our students and give them opportunities to practice metacognition, they won’t develop this important skill. And they won’t improve. Read More...

EdPuzzle

Adam Mills, OAPT Workshop Coordinator, Teacher - Assumption College Catholic High School
adam-mills@wecdsb.on.ca

One tool that has really helped change the look of my Physics classroom is Edpuzzle. https://edpuzzle.com/ Edpuzzle is a website that allows teachers to embed questions within videos already created from YouTube or other sources. I find this tool particularly useful to help minimize the amount of direct instruction that I am giving my students in class. This allows my students more time to participate in richer educational strategies such as peer instruction, cooperative group problem solving and inquiry based learning. Read More...
