Why are floods and droughts happening more often?
Lesson Objectives...
Develop a model to explain how a small change in temperature can cause large scale changes in precipitation leading to floods and droughts.
Develop a model to explain what could cause an increase in temperatures that are linked to an increase in floods and droughts.
Ask questions that arise from initial observations of stories and headlines about rising temperatures, floods, and droughts to clarify whether increasing temperatures are related to or causing both floods and droughts.
