A few of the things that drive physics teachers nuts. Watch this so you know the what you need to remember so you don't lose marks. Physics Pledge

It seems so long ago that we hit 1 million views. Thanks for your support 1 Million Views Thank You Video

Our most entertaining video, you need to see the original Big Bang Theory, Eye of the Tiger video to appreciate this one.
Okay, we went a little overboard on this one when we hosted the teacher talent show at our school
Perhaps we also went a little overboard on this one
Can you believe that 100,000 views seemed like a big deal at one time
We won an Excellence in Education award and this is the video produced by the TDSB for the ceremony.
Okay, so we think we're funny.
This is where it all started
