Help
- Investigating the Climate System: Energy - offers lessons that focus on questions: Does ground surface influence temperature? How important is water evaporation to the cooling of a surface? If my town grows, will it affect the area's temperature? Why are summer temperatures in the desert southwest so much higher than at the same latitude in the southeast? (NASA)
