I suppose you want to know how the unit is going. The Book of Days project was wonderful. Check out the pictures!
We've read about Ghiberti and the Doors of Paradise in Learning Through History magazine, and are looking at bronze bas relief. Then following the instructions here, we are making our own plaster bas reliefs. First we are making the forms out of modeling clay. This week we will be making the casts out of latex, and then making the plaster casts. I'll try to keep photos to show our progression.
This week we also are going to be learning a bit more about Gutenberg and his printing press. I've got a few books on Gutenberg, and also have read some from the Famous Inventors book over at Baldwin Project.
