The Intersection of Science and Small Contractor House Construction

Dave Gervais, Chair STAO Safety Committee, construction worker

The options for your students that drop out of high school or graduate with high school are very limited. After rolling through the low paying jobs of the service sector, restaurant or retail business, construction work looks pretty good. How do the science and mathematical principles and calculations in construction compare to that taught in our science classes? Read More...

Webinars and Video Calls in the Classroom

Stacey Joyce, Program Manager at Partners In Research Canada (PIR)

I’m sure that you employ a variety of tools and strategies in your classroom, including inquiry activities, independent or group projects, “assessments as, for and of” learning… the list goes on. But how do you and your students answer the questions they come up with during or after the initial inquiry activity? What types of resources do you teach students to use for their independent research? How do you introduce the students to career options that use Physics?

Here’s where video calls and webinars come in, and don’t think that you can’t afford these options — they’re free from Partners In Research Canada (PIR)! Read More...

Why is STEM Important to Physics?

Dave Doucette, OAPT Vice-President

Lisa Lim-Cole OAPT Past President

A recent OAPT Newsletter article from John Caranci laments the fact that over the past decade, despite an increase in the total number of Ontario grade 12 physics credits, the percentage of females has remained at around 31%. John insightfully suggests looking at elementary education and we agree. But to better understand the challenge we need to have a good understanding of the shifting landscape in elementary education. The inquiry-based learning approach which anchors the curriculum is now being stressed by a newcomer to the field: STEM education. The good news is that STEM and inquiry are totally complementary — and both require habits of mind exemplified by physics instruction. If we work together to support K-8 educators in successfully marrying inquiry with STEM education, we are likely to see far more students selecting secondary physics course, including more females. A worthy goal! Read More...

Introducing an Interdisciplinary Course (IDC) at Your School

Steve Fotheringham, OAPT Exhibit Hall Coordinator, Teacher Oakville Trafalgar High School

Have you ever looked at your schools’ course offerings and noticed that some need is not being met? Perhaps the course selection for your applied-level learner is uninspired or there are no elective courses that encourage students to apply their imagination or creativity. Perhaps, what you are looking for does not exist on the list of courses in Ontario.

I’ve had this thought many times and have since had the privilege of introducing two new courses to my school — “Engineering Design” and “Leadership”. Both made use of the incredibly flexible IDC course code.

The purpose of this article is to share with you a few of the lessons (in no particular order) that I have learned along the way which in turn may help you introduce a new course in your school. Read More...

PER Corner: Fixing the Gender Imbalance in Physics

Chris Meyer, OAPT VP teaching and learning, Assistant Curriculum Leader York Mills C. I.

I have a problem in my physics classes: by grade 12, only one third of the class is female. I used to think of this as a fact of life, or something beyond my power to change, but now I am sure that is wrong. Too many girls are missing out on some of the best training in critical thinking available in high school. Research suggests why: girls experience physics education differently than boys do. By understanding these differences, I am modifying my classroom to create an environment that supports girls and encourages their future participation in physics. Read More...

Energy and Motion Connections in a K’Nex™ Catapult

Margaret Scora, Teacher at Monsignor Paul Dwyer CHS

It is very important to have our students engaged in the classroom in order for deep learning to occur. Your students need opportunities to use their creative spark and build on their 21st century learning skills. Peter Benson’s TED talk does a great job of presenting how important this is.

Ideas for projects proliferate but many of these are time-consuming, expensive and beyond the skills of an average student and the tools of an average physics classroom. However, your students can build a catapult with K’Nex™ in just one class with virtually no prep and no trips to the wood shop.

Review: The Martian

James Ball, OAPT Membership Chair, Physics Teacher, John F. Ross C.V.I.

Rating: 4.5 out of 5 luminous gaseous bodies

The Martian is a very entertaining movie, which will appeal to a wide audience. As a physics/science/science teacher I found it to be particularly enjoyable.

I’m going to review it according to the science, technology, engineering and math that it presents (yup that’s STEM). Read More...

A Numbers Game: the Significant Digits Racket

Chris Meyer, OAPT VP teaching and learning, Assistant curriculum leader York Mills C. I.

OK, let’s begin by admitting that we are all playing a numbers game. Or, at least, we make our students play this game where they bet their marks on correctly figuring out the last digit to write down in their answers. (The classic numbers game is an illegal betting pool where people try to guess the last few digits of some “random” number like a stock price listing.) To make it sporting, we teach our students rules for identifying the significant digits in a given number and rules for deciding how many digits to keep after a calculation. Now, you likely know what happens next. For the rest of the year we are plagued by noisome questions during lessons and tests: “How many significant digits does this have?” “Is this two or three?” “Mr. Meyer, you started with 1000 and your final answer was 17.5 m/s ...” Sound familiar?

Barges: STEM Competitions for grades 9 to 12

Roberta Tevlin, Danforth Collegiate, Past President of OAPT

Competitions are a great way to motivate students, to provide a rich learning experience and incorporate the STEM disciplines and problem-solving approach. Unfortunately, it can be hard to find competitions that are appropriate. They need to be challenging but not impossible. They must use cheap materials and tools and should not require significant building skills. If possible, they should require precision in measurement and calculations. One competition that does all of these; and not only that, it has curriculum connections ranging from grade 9 Science to grade 12 Calculus, is “Barges”. Read More...

Making Speakers

Bonnie Lasby Physical and Engineering Science Dean’s Office University of Guelph

I prefer to do this as an activity as opposed to a demonstration, and have found that it works very well for students in Grades 7 to 12 visiting the University. I start with a discussion about sound and then compare a speaker to the human ear. In the discussion on speakers, I also talk about magnets and how they work, and I explain the difference between permanent magnets and electromagnets. After this discussion, I explain how to make speakers using a plastic cup, a magnet, and a coil of wire. Each student makes his/her own speaker and then tests it. Read More...

A Crazy Cantilever

George Vanderkuur, WICED Centre, TDSB

Bricks, books, or metre sticks are all you need for this neat demonstration. As illustrated, the top brick projects by half its length and subsequent bricks project 1/4, 1/6, 1/8, et. Brick lengths. After n bricks, the cantilever will project a distance of d = 1/2 + 1/4 + 1/6 + … + 1/(2n). This may be simplified to d = 1/2 (1 + 1/2 + 1/3 + … + 1/n). For four bricks, the projected distance is 1.04 brick lengths, and for n = 5, the distance is 1.14 brick lengths (so that the top brick is clearly out beyond the edge of the table). Read More...
