https://padlet.com/andrea_neises/1bqglt2cfkbv8ijt Steps to creating Unit Padlet Essential Knowledge study guides: (1) Go to the APES CED: https://apcentral.collegeboard.org/pdf/ap-environmental-science-course-and-exam-description.pdf (2) Scroll down to the Unit and Topic (3) Copy an Essential Knowledge statement, and paste it as a Padlet post. (4) Read and modify the statement to clarify (if needed) & give the post a title that conveys the meaning. (5) Select an graph, infographic, diagram, or image that effectively represents the post. en-us 2020-04-29 16:36:46 UTC 2026-01-17 13:25:23 UTC hello@padlet.com https://padlet.net/icons/png/1f30e.png andrea_neises https://padlet.com/andrea_neises/1bqglt2cfkbv8ijt/wish/539739763  Biodiversity in an ecosystem includes genetic, species, and habitat diversity. ]]> 2020-04-29 16:39:49 UTC https://padlet.com/andrea_neises/1bqglt2cfkbv8ijt/wish/539739763 andrea_neises https://padlet.com/andrea_neises/1bqglt2cfkbv8ijt/wish/539744049  The more genetically diverse a population is, the better it can respond to environmental stressors.
