Students always struggle with the difference between weathering (the breakdown of rock in situ) and erosion (the breakdown and removal of material by water and wind) in geography. I like to use some simple technology to model this process – sugar cubes and water.
Today one of our students used the slow motion camera feature on the iPhone 5S to film the water absorbing into the sugar cube. This is the first time I’ve seen the use of this camera feature in class (not available on iPhone 4, 5C or iPad unfortunately) and provides so many possibilities for supporting learning concerning things that normally happen too quickly to fully comprehend e.g. techniques in sport, chemical reactions and experiments in physics.
