Lesson 1: Causes and Evidences of Climate
Students will be able to:• Identify an evidence of climate change, focusing
on the relationship between CO2 concentrations and atmospheric temperature.
• Describe the greenhouse effect and identify the gases involved in it.
• Describe how carbon enters the atmosphere as depicted by the carbon cycle
• Identify sources of CO2 emissions

Carbon dioxide
Methane
Nitrous Oxide
Flourine gases
List of terms:
• Fluorine Gases
• Methane
• Carbon Dioxide
• Nitrous Oxides
Global temperatures vs. CO2 concentrations • Split into pairs• Using the table provided in your worksheet, have
one person create the graph for global temperatures and one person create the graph for CO2 concentrations.
• Now compare these two graphs. What is the correlation between global temperature and CO2 concentrations?
CO2 Concentrations:1980-2010
Global Temperature:1980-2010
How does Carbon enter the
atmosphere?Word Bank:
• Auto and factory emissions
• Animal Respiration
• Dead Organisms and waste productions
• Fossils and Fossil Fuels
• Plant Respiration
• Photosynthesis
• Sunlight

Fossil fuel combustion for Transportation
Industry use of fossil fuels
Residential and Com-mericial use of fossil fuels
Other (Non Fossil Fuel Combustion)
Word Bank:
• Burning fossil fuels for Transportation
• Fossil fuel consumption to produce Electricity
• Residential and Commercial use of fossil fuels
• Other (Non fossil fuel combustion)
• Industrial use of fossil fuels
Activity: PictionarySources of CO2 emissions
• The teacher will split you up into groups of four or five.
• Pick a person to start• Start the timer for one minute• The first person to start will draw a source of CO2
emissions• The rest of the group will try to guess what the
source is before time is up
So how can we reduce CO2 emissions?
HomeworkStudents will complete the following activities, like a scavenger hunt.• Find a brief story from someone you know about
how Climate Change affects him or her. Write down a description of this story.
• Find an object (a picture or the object) you use or describe an activity you encounter in your life that emits greenhouse gases.
• Describe a new way to use this object or complete this activity in a way that emits less greenhouse gases.
Lesson 2: Impacts of Climate Change
Students will be able to:• Identify the predicted impacts of a warmer
atmosphere on the earth, focusing on the water cycle and oceans
• Determine the impacts of climate change on animals and plants in El Yunque, focusing on the impacts of rising temperature and changing precipitation patterns.
