The Crayon Lab

































This is a great rock cycle simulation we do every year. 

1.  The first picture (the crayons with wrappers) represent a rock in nature. 

2.  The second picture represents the weathering process in nature (or, when rocks are broken down into small pieces). 

3.  The third picture represents the erosion and deposition process in nature (or when rock fragments are moved from one place to another and dropped in a new location). 

4.  The fourth picture represents the compaction and cementation process that rocks undergo as they become sedimentary rocks.

Parts 2 and 3 of this lab will take place on Wednesday, when we subject our sedimentary rocks to heat and pressure (metamorphic formation), and finally melt and cool our rocks (igneous formation). We will post further pics then!

Looks like fun! Too bad you can't eat the rocks when you are done!

Yeah, it wouldn't taste very good if they did!
