Instructional Ideas
- The video mentions that 50 percent of the heat appears to come from radiation, but doesn't explain the other 50; research to see what current theories explain the missing half
- Link this to survival skills - i.e., if you are in the desert and need a shelter, should you dig down or stay on the surface? If you find a cave or old mine shaft should you explore it or stay outside?
