Evidence of Climate Change
HITTING HOME: CLIMATE CHANGE IN COLORADO
How would we know if Colorado’s climate is changing & how will it affect us?
Created in the Making Global Local workshops, University of Colorado at Boulder
The driving question for "Evidence of Climate Change" is "How would we know if Colorado's climate is changing and how will it affect me?" Students warm up to the topic by discussing media coverage of climate change in Colorado, their own opinions about the topic and evidence supporting their hypothesis. Featuring video and power point presentations, data analysis and group presentations, the lesson concludes with each student writing a newspaper article summarizing the class findings. This lesson is designed for middle school science students, but is adaptable to older students.

Introduction to Lesson
Is climate change happening in Colorado? It’s important to approach such questions from a rational and scientific viewpoint, by examining actual data. In this lesson, students are given a set of observational data and asked to determine whether it supports or does not support the hypothesis that climate is changing over time in Colorado.
Lesson Sequence
Engagement
News stories in the local papers talk about climate change occurring in CO. What are your thoughts on this subject? What evidence would you use to support your hypothesis?
(Do a think pair share and have kids report out)
Show two climate videos from http://learnmoreaboutclimate.colorado.edu:
i. Clip #1: Colorado and a Warming Planet (8:51)
ii. Clip #2: Hotter, Drier Colorado (7:59)
Analyzing Data
1. Model how to fill out the Part A: Individual and Group Observation sheet with the class
2. Divide each class into 8 groups and assign them one of the following topics, giving the relevant Evidence Cards for that topic:
1. Snow Pack
2. Yearly Precipitation
3. Average Yearly Temperature
4. Frequency of Forest Fires
5. Peak River Flow Days
6. Glaciers
7. Changes in Latitudinal Location of Bird Species
3. In groups have students fill in the topic and their hypothesis on the Part A: Individual and Group Observation sheet
1. Formative questioning
4. Then have students analyze the data and fill in the rest of the Part A: Group Data Analysis sheet
5. Assign a recorder, a presenter, facilitator, time keeper within the group
6. Give students time to prepare their presentations
7. Hand out the Part B: Summary of Group Data sheet
8. Have each group present; at the conclusion of each presentation have students fill in the appropriate part of the Part B worksheet
9. Summarize all of the findings with the class Share out – 3 minutes max
1. Questions for how all this evidence shows climate change.
1. What data did you look at?
2. What were your results?
3. Were you able to answer your question? If not why do you think your results were inconclusive?
4. Maybe you weren’t able to conclusively answer your question or if you didn’t obtain group consensus…what were the areas of conflict? What other information would you need to answer your question?
2. Pulling it Together
1. What trends did you notice in the overall data?
2. What was it like to support your claims using the evidence provided?
3. How this is important to our lives?
10. Show a Colorado Climate Video from http://learnmoreaboutclimate.colorado.edu
1. Listening to Colorado's Ecology
2. Colorado and a Warming Planet (8:51)
3. Hotter, Drier Colorado (7:59)
11. Hand out Part C: Conclusion worksheet and have students write a newspaper article summarizing the class findings

Why Should We Care?
How will climate change affect Colorado's native species? Will invasive species increase?
Will climate change affect our water usage? Will we have enough water?
How will economic industries like agriculture be affected by climate change? Will we lose jobs?
What kinds of new jobs may be formed in response to the need for reducing our carbon footprint?

Climate Literacy Essential Principles Addressed
Standard 4: Earth's weather and climate systems are the result of complex interactions
Interaction between various climate components can produce emergent phenomena unique to the system. Humans are an integral part of Earth's climate system. Human activities such as fossil fuel burning or deforestation can affect climate and alter the equilibrium of the climate system.
Standard 6: Evidence indicates human activities are impacting the climate system
Colorado State Science Standards (New standards)
High School
PS5. Energy exists in many forms such as mechanical, chemical, electrical, radiant, thermal, and nuclear, that can be quantified and experimentally determined PS6. When energy changes form, it is neither created not destroyed; however, because some is necessarily lost as heat, the amount of energy available to do work decreases LS2. The size and persistence of populations depend on their interactions with each other and on the abiotic factors in an ecosystem ES4. Climate is the result of energy transfer among interactions of the atmosphere, hydrosphere, geosphere, and biosphere ES6. The interaction of Earth's surface with water, air, gravity, and biological activity causes physical and chemical changes
8th Grade
PS2. There are different forms of energy, and those forms of energy can be changed from one form to another – but total energy is conserved PS3. Distinguish between physical and chemical changes, noting that mass is conserved during any change LS1. Human activities can deliberately or inadvertently alter ecosystems and their resiliency ES1 Weather is a result of complex interactions of Earth's atmosphere, land and water, that are driven by energy from the sun, and can be predicted and described through complex models ES2. Earth has a variety of climates defined by average temperature, precipitation, humidity, air pressure, and wind that have changed over time in a particular location
7th Grade
LS1. Individual organisms with certain traits are more likely than others to survive and have offspring in a specific environment
6th Grade
LS1. Changes in environmental conditions can affect the survival of individual organisms, populations, and entire species LS2. Organisms interact with each other and their environment in various ways that create a flow of energy and cycling of matter in an ecosystem ES2. Water on Earth is distributed and circulated through oceans, glaciers, rivers, ground water, and the atmosphere
