Evidence-Based Writing & Exit Ticket
Students complete the "Climate Analysis" worksheet.
OSAS-Style: Encourage students to cite specific paragraphs in their writing.Closure: Collect exit tickets for a quick formative check on the definition of Climate Change.
Pro-Tips for Delivery
Managing Eco-Anxiety
The video is intense. Remind students that understanding the mechanism is the first step toward finding solutions. Focus on the "science" part today.
Clarifying Misconceptions
Many students confuse "Global Warming" with the "Ozone Layer." Be ready to clarify that the Greenhouse Effect is about trapped heat, not a hole in the atmosphere.

Weather vs. Climate
Weather
Short-term state of the atmosphere. Happens right now!
"It's raining today."
Climate
Long-term patterns of weather in a region over 30+ years.
"Summers here are usually hot."
The Greenhouse Effect
1
Sunlight reaches the Earth's surface.
2
Some energy is absorbed, some is reflected back as heat.
3
Greenhouse gases (like CO2) trap that heat in the atmosphere.
The Atmosphere "Blanket"
The Human Element
Why is the blanket getting thicker?
Fossil Fuels
Burning coal, oil, and gas releases stored carbon into the air.
Deforestation
Trees absorb CO2. Cutting them down means more CO2 stays in the sky.
Global Warming
The average temperature of the whole planet rises over time.

What Is the Greenhouse Effect?
Understanding the Earth's natural thermostat—and why it's heating up.
Imagine you are sitting in a car parked in the sun on a bright afternoon. Even if the air outside is cool, the inside of the car feels much warmer. This happens because the sun’s light passes through the glass windows and is absorbed by the seats and the dashboard. These objects then radiate that energy back as heat. However, unlike the light, the heat cannot easily pass back out through the glass. It becomes trapped inside, causing the temperature to rise.
This is exactly how the Greenhouse Effect works on a planetary scale. Earth is surrounded by an atmosphere—a layer of gases that acts like the glass in that car. Without this effect, our planet would be a frozen wasteland with an average temperature of about -18 degrees Celsius (0 degrees Fahrenheit). The Greenhouse Effect is a natural and necessary process that keeps Earth warm enough to support life.
Key Scientific Term: Greenhouse Gases
Not all gases in our atmosphere trap heat. The "greenhouse gases" are specifically those that can absorb and emit infrared radiation. The most significant ones include Carbon Dioxide (CO2) , Methane (CH4) , and Nitrous Oxide (N2O) .
For thousands of years, the amount of greenhouse gases in our atmosphere stayed relatively stable. However, starting in the late 1700s with the Industrial Revolution, humans began to change this balance. We started burning fossil fuels —like coal, oil, and natural gas—to power factories, cars, and electricity. When these fuels are burned, they release massive amounts of stored carbon dioxide back into the atmosphere.
At the same time, large-scale deforestation (cutting down forests) has reduced the number of trees available to absorb carbon dioxide through photosynthesis. With more CO2 being added and fewer trees to take it out, the "blanket" of gases surrounding the Earth is getting thicker.
As this blanket thickens, it traps more and more heat. This leads to Global Warming , which is the unusual rapid increase in Earth’s average surface temperature over the past century. This warming doesn't just mean hotter summers; it disrupts weather patterns, melts polar ice, and causes sea levels to rise. Scientists refer to these long-term, large-scale changes as Climate Change .

Part 1: Defining the Difference
Based on the slide deck and article, identify if the following statements describe Weather or Climate .
"The average temperature in the desert is 100°F during the summer."

"It is currently snowing in Portland, Oregon."

Part 2: Text-Dependent Analysis
1. According to the text, why is the greenhouse effect considered a "necessary process"? Use evidence from paragraph 2 to support your answer.
2. How does the author use the analogy of a car parked in the sun to explain the greenhouse effect? Explain the connection between the "glass windows" and the "atmosphere."
3. Based on the article, identify two human activities that are contributing to the increase in global temperatures. Describe the specific scientific reason why each activity causes warming.
Part 3: "I Wonder..."
Scientific inquiry starts with questions. Based on today's lesson, write two questions you still have about climate change.

Part 1: Defining the Difference
"The average temperature in the desert is 100°F during the summer." CLIMATE (C)
"It is currently snowing in Portland, Oregon." WEATHER (W)
Part 2: Text-Dependent Analysis
Q1: Why is the greenhouse effect "necessary"?
Expectation:
Students should cite paragraph 2. Without it, Earth would be a "frozen wasteland" (avg. temp -18°C / 0°F). It is necessary to keep Earth warm enough to support life.
Q2: Car analogy connection?
Expectation:
Just as glass lets light in but traps heat inside a car, the atmosphere acts like the glass. It allows sunlight to pass through but traps the resulting heat energy (infrared radiation) from escaping back into space.
Q3: Human activities & scientific reasons?
Burning Fossil Fuels: Releases massive amounts of stored carbon dioxide (CO2) into the atmosphere when burned for factories, cars, or electricity.Deforestation: Cutting down trees reduces the planet's ability to absorb CO2 through photosynthesis, leaving more of the gas in the atmosphere.
