The first Science unit we are covering in Gr. 3 is about soil. Over the last few days the kids have been digging around in soil, looking at it through magnifying glasses and sharing our observations. We've sorted through soil and looked at the organic matter (leaves, bugs, twigs etc.). We had a lot of squeals when we happened upon some beetles and ants.
Today kiddos started learning about sand, silt and clay-the particles that make up soil. Sand, silt and clay refer to the size of the particles found in soil. Sand is the largest, then silt and then clay. Today we dug around in soil looking to see if we could find some sand, silt or clay particles. It was messy and fun-they way Science should be!
