Forest School Rocks!

Here we are using a soil auger – basically a drill for the soil. We dug down to see the humus, top-soil and sub-soil layers. It was amazing to see the different colours and feel the textures as the soil got sandier deeper down. Using magnifying glasses, we examined rocks in the soil and discovered they were mostly made up of grains making them sedimentary. There were a few rocks with crystals inside showing us they were metamorphic or igneous.
