Digging Deep with Climate Proxies: An Exploration into Climate, Inquiry Science
and Scientific Literacy
2015 NSTA National Conference, Chicago IL
Mark Goldner 7th/8th Grade Science Teacher Heath School, Brookline, MA
Digging Deep with Climate Proxies: An Exploration into Climate, Inquiry Science
and Scientific Literacy
� Warm-up: Who’s your Audience?
� Project outline: � Sediment Coring and Analysis
� Interacting with Climate Scientists
� Creating Podcasts
� Literacy Connections
� Logistics & How you might adapt this to your classroom setting
Thanks to… � PolarTREC - Janet Warburton and Sarah Bartholow

Warm up: Who’s Your Audience?
� Think of a favorite project or activity that you have your students do.
� Who is/are the audience(s) for this project?
� How do you think having an identified and authentic audience affects student performance on a project?
Importance of Authentic Audience
� Listen to the Podcast.
� Who are the potential audience(s) for this piece?
Project Goals � Content Goals:
� Explain what the Greenhouse Effect is and how that explains our current climate change.
� Use data to make claims about short-and long-term trends in climate.
� Describe examples of how proxy data is used to understand past climate and model future climate trends.
� Nature of Science Goals: � Use hands-on experiences to gather data and make claims
based on evidence � Learn the stories of research experiences from real
Scientists � Improve Scientific Literacy through reading, writing,
listening and speaking
Climate Change: How do we know? � Proxy = indirect measurements that stand in for direct
measurements
� Proxies are often JUST as reliable as a direct measurement would be
Examples of Climate Proxies
� Sediment: � Isotopic signatures in organic matter
� Pollen � Diatoms
� Ice Cores
� Tree Rings
� Corals
� Historical Records
Inquiry Science � Hands-on
� Students doing Real Science and asking authentic scientific questions
� Feels important
Project Part 1: Overview of Climate Change
� Introduction to the current climate crisis
� Overview of the greenhouse effect model
� Looking at data – CO2 and temperature data from the past 3 million years or so.

Project Part 2: Sediment Coring and Analysis
� Sediment collected from local pond and river.
� Core descriptions, including color and texture analysis.
� Connect with known events (construction, flooding, etc.)
� Make Claims based on Evidence
Project Part 3: Extending our understanding of proxy data
� RadioLab Story about Corals and Day Length:

Project Part 3: Extending our understanding of proxy data
� Climate Change in the Sahara: Observing 9000 years of changing climate.
� Lake El’gygytgyn Sediment Study: Observing climate changes from 400,000 years ago
Project Part 3: Extending our understanding of proxy data
Project Part 4: Learning about a researcher who uses climate proxies
� Students Read and discuss (Close Reading and Discussion)
� Summarize and share (Close Reading and Summarizing)
Project Part 4: Learning about a researcher who uses climate proxies
� Blog Discussion following summaries
Project Part 4: Learning about a researcher who uses climate proxies
� Generate Questions: Focus on Using climate proxies to understand climate in past/present/future
Project Part 5: Creating the Podcast
� Listen to researcher recordings and discuss (Close listening and discussion)
� Summarize (Close listening and summarizing)
Project Part 5: Creating the Podcast
� Planning and Writing a Script
� Recording and mixing audio (using QuickTime and GarageBand)
Project Part 6: Share with wider audience
� Main audience is other middle school students.
� I published the podcasts using BuzzSprout and embedded them into a wordpress site: climateproxy.sciencegold.com
Literacy Connections � Reading:
� Reading articles about researchers � Reading graphs and data
� Writing � Recording Observations � Summarizing Reading � Writing Blog posts and comments � Script writing
� Listening � Listening to Researcher recordings � Listening/commenting about peers’ recordings
� Speaking � Small Group Discussions � Recording Voices in Podcast
