Soils & the Environment

Fall 2013

pencil.pngStudents were asked to think about soils. Their thinking and our learning through the unit may be found below. Facts (things found to be true) will be highlighted. Things we thought were true but are 'false' will be crossed out. This isn't a bad thing - it just means we were able to correct/add to prior learning. That happens to scientists all the time!
