Middle school STEM teachers may be interested in this free climate change curriculum developed by the Environmental Literacy and Inquiry (ELI) Working Group at Lehigh University. Designed to take place over 21 days or class sessions, this technology-supported curriculum "focuses on essential climate literacy principles with an emphasis on weather and climate, Earth system energy balance, greenhouse gases, paleoclimatology, and how human activities influence climate change." Throughout the curriculum's six thematic units, students complete inquiry-based lab activities using tools such as Google Earth, a web-based carbon calculator, and a geologic timeline to investigate these interrelated climate change topics. This comprehensive, standards-aligned curriculum provides all the necessary instructional materials and supporting information, including an instructional framework and sequence, assessments (including a pre- and post-test), Google Earth files, videos, PowerPoint files, handouts, and homework readings, as well as resources for students and background information for each topic. ELI advises that these curricular materials work best using Google Earth version 5.2 or newer and Firefox. It should be noted that access to the assessment files requires a login, which interested teachers can acquire for free by emailing a request to the contact email found in the site's footer.
