Different people have various kinaesthetic ways of making tectonic plate boundaries ‘sticky’. I used this idea when teaching tectonics last year, students changed the position of their hands to represent the different plate boundaries.
There is a practice, then the names of the boundaries appear and students have to show the correct hand positions, its timed, to make it a little more challenging. Add some music and it’s an enjoyable plenary.
Remember to show the power!
