Maintained by the BBC Education Web site, The Rock Cycle Experiments page contains ten activities related to the rock cycle, beginning with weathering and ending with the uplift of rocks. Each activity pops up after clicking the link within the very well done interactive diagram of the rock cycle. The activities are simple but effective; for example, the transportation lesson has students run water through sand to see its effects. The hands-on experience of the activities helps reinforce the learning and of course makes it fun.
