In class we went outside and observed the soil profile and had an DIRTY good time.  Your job is to be a SOIL SCIENTIST and investigate the layers of soil at your house. Your job is to create a soil profie (similar to the picture on the left) and label and name the soil horizons or layers.  You are to put the soil you collect into small sandwhich bags and attach them to a poster .  You get to be as creative and artistic as you want.

-Collect a baggie of each type of soil and staple to a sheet of THICK construction board and answer the following questions.  This will be added as 20 points EC on a TEST grade.   Click the more button to see the project details!
