This Power Point presentation is a general discussion of the rock cycle, igneous, sedimentary and metamorphic rocks, weathering and erosion. It is meant for grades 6 through 9, depending of the level of the class. The material to be covered in your particular class will determine if you need to add anything to the presentation. I suggest supplementing the presentation with actual rock samples and appropriate videos. Some classes may do activities to actually identify rock samples.
There is a worksheet to be used along with the Power Point.
