Check out my Google Drive link to all folders and documents on unit plans. If you decide to use any of my ideas for a lesson, please shoot me a comment either here or on Twitter so I know my knowledge is being shared. Thanks so much and hope these can be of use!
There is a folder for a soils unit, a folder for a habitats unit, and a folder to various random 1-part lessons I did in my pre-internship. You can always check back later, as I will likely add more unit plans and lesson plans as I find them.
