  13. 13. More Online Resources
  14. 14. Ecological Misconceptions Students may think: Ecosystems are not a functioning whole but simply a collection of organisms. Ecosystems include not just the organisms but also the interactions between organisms and between the organisms and their physical environment. Formative assessment, targeted instruction focusing on relationships
  15. 15. Arctic Creatures Mobile Students read about diatoms, copepods, Arctic cod, ringed seals, walruses, and polar bears. They create a mobile to represent the interactions between organisms in the arctic food chain. Download an accompanying podcast from the magazine or iTunes!
  16. 16. Making the Forest and Tundra Wildlife Connection
  17. 17. Wolf and the Moose Donna Dewhurst, US FWS Simulate predator/prey relationships through a tag-like game Vary numbers of predator and prey to reflect changing conditions Follow-up discussion to extend understanding Modify activity for other animals Andrew Johnson, Flickr
  18. 18. Bearly any Ice A variation of the predator/prey tag activity that includes declining sea ice as a result of climate change. Encourages students to consider the impact of changing environmental conditions on food webs and ecosystems. Amanda Graham, Flickr
  19. 19. Poll #2 A common misconception elementary students have related to energy flow of ecosystems is that: <ul><li>Students rarely think energy is measurable and quantifiable. </li></ul><ul><li>Students tend to associate energy only with living things, in particular with growing, fitness, exercise, and food. </li></ul><ul><li>Students have difficulty in identifying the sources of energy for plants and also for animals. </li></ul><ul><li>All of the above. </li></ul>Select your answer by pushing on your touch tone pad --from Atlas of Science Literacy, Project 2061, AAAS
