Build an Arcade Game — A STEM Project

Nassi Rafiee, teacher Toronto DSB

Many grade 12 physics students plan to pursuit engineering in their post-secondary studies. Surprisingly, many lack a clear idea about the required skillset and what to expect in their next 4 years of education.

Last year I came up with the idea of having students design a mechanical pinball machine that demonstrates the mechanics concepts in grade 12. It was originally intended to focus on team building, engineering design process, physics calculations and writing skills, however as soon as I shared the idea with students, they got so excited that they formed their groups immediately and insisted that they wanted to build it too.

Rockets: A Beginners Guide Part 3

John Berrigan, Teacher Oakville Trafalger H.S.

In the previous article we found the main factors that determine the thrust of a rocket engine. We rearranged the formula and determined the Impulse of the formula for rockets.EQN1 With Elon Musk discussing his Mars rocket last week, http://www.spacex.com/mars, now is a good time to discuss how Impulse can be used to eventually determine the efficiency of a rocket engine.

Rockets: A Beginners Guide Part 2

John Berrigan, Teacher Oakville Trafalger H.S.

In the previous article we learnt how to find the largest possible delta-V that a rocket can experience. In this article, we are going to find the thrust of a rocket by using the fundamentals of conservation of momentum. This will be similar to what we did in the last article, however this time we will use variables instead specific masses and velocities. Furthermore, the cart is now a rocket, as this is rocket science! Read More...

A Browser-Based No-Fuss Gravitation Simulator

Michel Enns, Teacher Runnymede CI

I have been frustrated with gravitation simulators over the years because they stop working when the computers are updated. To avoid this, I have made one that is browser-based and will run on any device. You can find it at www3.sympatico.ca/michael.enns. One non-standard thing that it can do is simulate the formation of a solar system with a thousand random masses. Read More...

Rockets: A Beginners Guide Part 1

John Berrigan, Teacher Oakville Trafalger H.S.

Interest in rockets is skyrocketing due to the recent successes of SpaceX and Blue Origin, two private companies developing spaceflight. This is an ideal time to introduce students to the physics behind rockets which are an exciting illustration of the conservation of momentum and relative motion.   Read More...

Physics On Ice: A Field Trip on Force and Motion

Margaret Scora, Teacher at M. Paul Dwyer CHS, Oshawa ON

Taking a class to Wonderland™ to investigate force and motion can be an expensive and frustrating adventure. The local ice rink is probably only 15 minutes away for most of us, a lot cheaper, and you can be there and back in less than three hours with a whole lot of new experiences for your students to ponder and discuss.
