Everyone Counts (post-assessment)
Protecting Earth's Atmosphere
To focus student’s attention for this activity, begin by asking, Have you ever heard of global warming? What about the layer of Earth’s atmosphere called the “ozone layer”? Do you think global warming can permanently change Earth’s climate? Why is the ozone layer so important for life on Earth? Follow the discussion by asking, What can we do to protect Earth from global warming and ozone depletion?
Guide students into a class discussion about the importance of the sun as a source of heat and other energy on Earth. Explain that Earth’s climate and our lifestyles are dependent on the sun’s energy, and that an increase in Earth’s temperature (global warming) can drastically change life on Earth.
Tell students they will be writing persuasive letters to each other, related to global atmospheric change. Introduce letter-writing skills if needed. Mention that global atmospheric change is a broad category that includes global warming and the loss of the “ozone hole.” Also, mention that all of us do things every day that contribute to atmospheric change.
Keywords: lesson | energy | sun | atmosphere | Earth | climate | global change | global warming | atmospheric change | global warming | ozone
