Introduction to Global Warming
- Grade level: Middle School, High School
- Subject Area: Science
Students gather information about global warming and
climate changes in preparation for future lessons on the Greenhouse Effect.
During this lesson, students will read about global warming using printed and on-line
resources. Students should
conclude this lesson with a grasp of the issues and concerns of how global warming might
affect life on this planet.
- Learn about global warming, evidence for global warming, and climate changes.
- Consider what might constitute sufficient evidence of global warming.
- Learn what impact global warming might have on our lives.
- Gain experience in researching using the Internet.
Materials and Resources
In developing our lessons and activities, we made some
assumptions about the hardware
and software that would be available in the classroom for teachers who visit the
LETSNet Website. We assume that teachers using our Internet-based lessons or
activities have a computer
(PC or Macintosh) with the necessary hardware components (mouse, keyboard, and
monitor) as well as software (operating system, TCP/IP software, networking or
software, e-mail and a World Wide Web client program, preferably Netscape, but
Mosaic or Lynx). In the section below, we specify any "special"
requirements for a lesson or activity (in addition to those described above)
and the level of Internet access required to do the activity.
hardware requirements: None.
- Special software requirements: None.
- Internet access: Medium-speed (28,000 BPS via modem)
or High-speed (greater than 1 MBPS via network).
Students work alone or in small groups
and research global warming and climate changes. Students can use printed or on-line
resources (see Internet Resources below) to learn about global warming, changes in the earth's climate
over time, atmospheric models that predict future changes, terminology, and possible impacts
of global warming on the earth.
- Students visit the Websites in the Internet Resources section and study global warming.
For example, visiting the "Index to Climate Change Fact Sheets" Website, students read about possible
causes of climate change, impact of climate change, and international response to climate change.
- As students research global warming, they should try to answer three questions:
- What evidence is there that the earth is actually warming up?
- What might be causing any global warming?
- What effect might global warming have on the earth's inhabitants?
- A good place for students to begin is the "Global Warming Terminology" Website. Here they will
find definitions of all the terms used in the debate on global warming.
- Another excellent Website is the "NOAA Global Warming Update", which includes graphs, text,
and models of global climate change developed by scientists at the National Climatic Data Center
- Teachers may want to visit the "GCRIO" Website (see Internet Resources for Teachers below) prior to beginning
this unit or lesson to gather additional printed materials for studying global warming.
