Use the iPad app AbcYa Animate to create an animation about the three parts of weathering. Here is a video a sixth grade student made using Keynote showing the same processes:
Weathering: the breaking down and wearing away of rocks
Erosion: wind and water carrying away bits of rock
Deposition: material eroded by water, wind or ice are dropped in a new place
See if you can put all the stages of weathering into one animation.
If you forgot how to use AbcYa Animate, here is a demonstration video:
