I presented at the International Society for Technology in Education conference in Denver on Tuesday. We shared the lessons that I wrote with Sean Moran and Victor Perez that used the 3D printed fossils in the middle school classroom. We were very well received and people were excited to have NGSS aligned lessons in the classroom that also utilized the 3D printing technology. I do have a couple of pictures on my phone, I believe they are the same ones online. I can email them to you if you would like. We are in California now for the kick off meeting of the iDigFossils project:)
Have an awesome 4th!
