Writing a series of newspaper articles about global warming sets the stage
for the Chapter Challenge. Students learn how and why global climate has
changed over time and what effects climate change has on the
community.
Students will:
Understand how changes in climate are tied to the Earth
System.
Participate in scientific inquiry and construct logical conclusions
based on evidence.
Recognize the global impacts of a change in climate.
Appreciate the value of Earth science information in improving the
quality of life globally and within the community.
