Alas, there are no videos at this time. The students had so much fun building their settlement and we didn't want to stop for screencasting. So the teacher, Mr. Fletcher, is letting them show their creations during class.
But, Monday was their final day in the lab for building. Tensions built as they soon discovered that their fortifications would be put to the test. The world was first saved, then, Mr. Fletcher, impersonating invaders of that time period, ransacked the villages spreading fire and witches and monsters across the landscape. One could certainly tell the exact moment when mayhem occurred as mixed squeals of terror and delight filled the room.
I must make one more remark - I am amazed when kids are in here for a week and there are no behavior issues - in any class period. They are so engaged and have experiences that no book or lecture could ever hope to provide.
