The wheel and fire, two technologies that changed our world in untold ways. However, I can almost gaurentee that if you asked 5th graders to name a technological advancement that changed their life none would say fire or the wheel. When teaching about technology, as is required by the 5th grade Social Studies curriculum, I want to get students thinking about not just the technology they see everyday (cell phones, computers, etc), but the technology from which all things have come.
