LOW and behold
Last week was lesson observation week (LOW). This means that teachers visit other classes. I visited a maths class and a chemistry class. The maths class were doing logs which reminded me about one of...
The bike's back
Today I was looking at some examples of balancing torques with my first year class and on the spur of the moment decided to consider a bicycle going in a circle. That's what the diagram shows by the way,...
Seesaw Marjorie Daw
Today I was introducing rotational motion and balancing Torques so naturally the conversation moved towards seesaws. I constructed some examples using Interactive Physics but what really got everyone...

Get out of that
I was introducing rotational mechanics to one of my first year classes, by showing some simulations with Interactive physics. First without gravity or pivots then adding complexity a bit at a time. So...
Coil magnet battery
"Coil magnet battery". That's what I googled to re-find this video that I saw on Facebook last week. At first sight it looks somewhat strange but when you start to think about it it's quite understandable....

Long and lonely road
Today I decided to leave GeoGebra alone for a bit and start to revise my Electricity lesson plans for the new syllabus starting with electric fields. So I wonder if I could model electric fields with...

Wiggle wrench
GeoGebra is excellent at showing the maths behind relatively simple examples but once you start adding friction, air resistance, damping etc. the maths becomes too complex. Algodoo does the maths leaving...
