Our own Green Learning MottoTread lightly upon the Earth.IMAGE CREDIT: http://i.treehugger.com/files/th_images/parkwheel.jpg
Why do Students like Green Learning?
The future is where they will live.Therefore, all students can be moved to care about the Earth.They grasp that they need to master the knowledge and skills needed to solve the global environmental problems we face.They like being role models for adults in conserving resources, promoting a sustainable lifestyle, and protecting Planet Earth.They wonder: How can we have a green future or a green economy without green learning? Who will teach us that? Why not YOU?
Teaching science in green-infused ways
Incorporate environmental themes and data into science classes to show students the applicability of science in everyday lifeUse news stories to connect global issues to your local environment and your subjectGet them active! Assess the health of a local stream, or perform an audit of your schools energy consumption and recommend improvements. Connect your course to the EarthCo-construct other timely ways to incorporate environmental themes into science lessons.
Green Checklists & Pledges
Teach them Blooms Taxonomy Emphasize learning, not grades
Create green task forcesIn each of your classes, students can:Walk around and look for course-related opportunities for green improvements in their classroom, school, and communityFocus on addressing one problem at a timeProvide scientifically based recommendations resources, and green science education to schoolmates, parents, teachers, and the administrationOperate a green student suggestion box:Helps build engagement, generates great ideasHelps set priorities among the problems they face
Adopt an environmental focus(here is one web-sourced thinking starter)
Teach them our class-based precautionary approachUse as a foundation for careful environmental decision makingIts slogan is: Better safe than sorry!STEPSTake anticipatory actionAssess alternativesExercise democracyChoose the safest solution
Some favorable outcomesGreen schools empower kids to make a differenceGreen schools teach them environmental and health values and habits that will stay with them for a lifetime Research studies showfor example-- that "daylighting" (increasing the amount of daylight in a building), improving indoor air quality, and hands-on, experiential environmental curricula are all linked to higher test scores
Thinking, feeling, acting
Free Video Course that weve used:The Habitable Planet is a multimedia course consisting of 13 units. Each unit is composed of a 30-minute video and an online text chapter. The web site acts as a home base to begin study, a place to organize the course materials. It provides access to all the course components plus additional resources, which include: 5 interactive lab activities;Visuals: animations and images used in the course; Harvard University environmental scientist biographies,Edited transcripts from each of the video case study interviews Web site URL: http://www.learner.org/channel/courses/envsci/index.html
The Global Education Projects Earth Wall Chart is Anthropocene-Panoramic Title: Earth: A Graphic Look at the State of the World. 100 Full-Color Graphs and Data Maps A Chapters Worth of Knowledge in Each Graphic Non-Partisan Information 27" by 36" Wall Chart (folded or laminated)http://www.theglobaleducationproject.org
Each year since global measurements of CO2 began, the amount of carbon dioxide in the atmosphere has increased.TIME SERIES OF STATES
The Chart Intervention:Research FindingsThe majority of students: (a) increased their personal knowledge of the distribution and limits of the Earth's resources [88%]; (b) shifted their knowledge and interest horizons from regional or national to global [72%]; (c) recalibrated their own professed personal consumption patterns to accommodate their new understandings of global resource realities [65%]; (d) expressed intent to reduce their ecological footprints[68%];(e) confided that the chart had impacted their personal discourse positions on Earth-related issues, and heightened the feeling that they were familiar and necessary stewards of Planet Earth [81%].
Infusing environmental topicsTeach the science first Teach with data Use active learning techniquesEmphasize student-generated problems Use controversy and topics with incomplete evidence constructivelyUse role-playing to protect studentsAssure all is not gloom and doomLead by example, but don't sermonize
The Coal Cycle:Science and Sustainability

http: EarthScholars.comAN EXAMPLE OF INFUSION
Multipurpose COAL!Coal fueled the Industrial Revolution, and changed the course of human history . . . and its history is OLDER than that recorded by humans!http://www.wvencyclopedia.org/assets/0000/7761/mine_safety2_up_medium.jpg?1276869681
A Coal Cycle

Coal CycleA subset of the Carbon Cycle:Photosynthesizing plants fixed carbonPlants provide organic sourceCarbon returned to atmosphere as plants decayedSome plants were buried and sequestered carbon
Coal: The OriginsBiochemical sedimentary rockPlant accumulation & compaction yield PEATPEAT is altered and compressed to LIGNITEAdditional alteration yields BITUMINOUS COALMetamorphosed coal is ANTHRACITE
Coal: The OriginsProcesses require MILLIONS of yearsChanging sea levels Rising sea levels drowned vegetation in swamps.Cyclothems record repeating marine and non-marine strata interbedded with coalhttp://earth.usc.edu/~stott/Catalina/images/paleoclimate/cyclothem.jpg

Coal Cycle in the ClassroomThe Coal Cycle can address concepts in biology, ecology, geology, chemistry . . . . .plus environmental stewardship and climate change
The Coal Controversy
Rationale for Teaching Legitimate Scientific ControversiesRecent research (Clark & Mayer, 2002) on learning indicates that including structured controversial topics in a course can heighten student interest, improve attention, and deepen understanding of the subject.
Almost every area we teach in the sciences has its scientifically controversial environmental topics, but many courses fail to introduce students to them for the sake of acceleration and expediency.
