About This Lesson
These are PowerPoints and sheets I use in lessons and will need some adaption to your classes. Most lessons start with a "Do now" that students do as they enter. I should mention that there are running jokes about my dislike of dogs (sorry!). See more at www.mrsimonporter.wikispaces.com
Some great slides in this resource about moments, levers and hydraulics. You will need to edit these slides as the author suggests and indeed I hope that the very first one is not a self image ;) Seriously, it is good to have this thought provoking material available for free use.
