Rock Cycle - Types of Rocks - Want to teach the rock cycle types of rocks in the most ENGAGING way?! The key to teaching rocks WELL is to teach one type at a time. You'll introduce one rock type at a time: identify and learn about the individual rocks in the group, read about how they form, how they are described and identified, and do an identification lab. Start with igneous, then move on to sedimentary and metamorphic. Finally, students will have a BLAST with my starburst rock cycle lab. Re
