Soil Excavation

November 19th
Today we learned about SOIL!  We discovered that soil isn't simply dirt, but rather it is composed of broken down rocks, minerals, decomposed plants and animals.  We also learned that some animals help make soil, and mix it up!  Insects such as ants help mix up the soil and worms can work to churn soil and also work to compost table scraps turning them in to rich soil!
We watched two short Learn360 videos and we also examined three types of soil.  Today we examined potting soil, peat moss and sand.  We were looking at the different particles that make up each of the soil samples.  We recorded our learning in our science notebooks.
