Celebrating my retirement after 25 years of teaching!
Rock Cycle:
I am terrible at rock identification, but I did learn to identify a couple samples of each type of rock. Conglomerate and metaconglomerates were the easiest for me: gravel sedimentary rocks and conglomerates heated into metamorphic rocks (also called pudding stones).
What was fun was taking a bunch of crayons, shredding them (weathering rocks), smashing the crayon sediments back together (sedimentary rocks), adding a little heat and pressure (metamorphic rocks), and liquifying them (igneous rocks). It was TOUGH to get just the right amount of heat and pressure to make metamorphic crayon rocks. Frequently, these rocks were still sediments or completely liquified. Igneous rocks were fun to make on a hot plate, but spills were known to happen and once they cooled, they still showed the different crayon colors since we didn’t stir them. Weathering the crayons took an entire class period and made a huge mess. Newspapers covering the tables helped, but crayon shreds were found stuck to the floor for days afterwards.
Remember: Geocaching is a hobby that you undertake at your own risk. Poison ivy, insects, mud and other aspects of the great outdoors may be encountered.
