Today I worked with Ms. Conrad to teach a lesson on the Bering Strait land bridge that once stretched from Asia to Alaska. I observed her for one period, then attempted the lesson for my class. I panicked right before the lesson began, so we decided to co-teach the lesson. She covered the major concepts - like why we measure time in BC/AD (dancing around the religious aspects of the dates), and what a theory is. I got to handle the fun part! A dramatic reenactment of the land bridge appearing during the ice age. Students played glaciers, the ocean, the Bering Strait, animals, and humans. I read a story in a dramatic voice about the Ice Age, and how the water of the Bering Strait and the Ocean receded, leaving a land bridge between Asia and North America. The students stood on a piece of butcher paper with the outlines of Asia and North America outlined. The animals and humans walked over the land bridge and ended up in North America. Tah-dah! A nice theory of how humans ended up on our continent.
