Swedish rope trick

Components in Algodoo
Todays video is by Maria, Teo and Yehya (I think). They chose to explain why a block slides as the angle of a slope is increased. To do this they needed to show the components of force acting down the...
International acceleration
Todays video is from Hazel (China), Mohamed (Iraq) and Lamine (Senegal). Again, good use of different approaches mixing live action with simulations done in Geogebra and Algodoo. I think Hazel has a fine...
Better to buy LoggerPro
Re posted in response to Ralph's request. After a recent (today) discussion on the OCC I thought I would see if its possible to do best fit max and min lines by eye in Excel. I thought it should be possible...
Projectile project

Falstad trick for old dogs
A couple of weeks ago I wrote about a neat way that two of my students had devised to draw straight lines in the falstad ripple tank applet well I have found a better way. I've been using this superb...
Plums or pla
Simulating an object oscillating with SHM in GeoGebra is easy but simulating a pendulum is tricky. The problem is that a pendulum bob moves in a curved path. A maths teacher friend of mine once showed...
Pig in space

Wonderful and superb!
Over the past 10 years I have led a lot of IB workshops which almost always include a session on the EE and that gives me the opportunity to tell some stories of my experiences, good and bad. One of the...
Video output
This week we have special 4 hour classes so I've got my students to make a video of one physical concept. Making a video activity I said I'd post them on my blog so here is the first one from Maria and...
