7The Grandma Johnson Problem Hypothetical Scenario: Grandma Johnson had verysentimental feelings toward Johnson Canyon, Utah where sheand her late husband had honeymooned long ago. Her feelingstoward this spot were such that upon her death sherequested to be buried under a creosote bush overlooking thecanyon. She loved the idea that she'd become part of thewonderful wilderness and live on through the wildlife thatlived there. Think to yourself and begin to trace the path of acarbon atom from Grandma Johnson's (GJ) remains to whereit could become part of a coyote (NOTE: the coyote WILLNOT dig up Grandma and consume any of her remains). Whatfundamental pathways and processes of biology will beinvolved in the transit of GJ's carbon atoms to that of thewild coyote in Utah?
8Task: Create a concept map that illustrates your understanding of the relationship between these 10 concepts in the context of the Grandma Johnson problem. You may add up to 5 extra concepts if you need them to explain the problem more clearly.photosynthesisrespirationcarbon cycledecomposersprimary producersconsumerscarbon dioxideglucoseenergyoxygen1. Work on the problem individually first, save it in CTOOLS, and print a hard copy Work on the problem with a partner. Both of you can retrieve your concept maps, discuss, revise and produce the best final map to which both of you have contributed Submit all three maps - yours, your partner's and the FINAL MAP you completed together - Please put the final map on top, with both of your names. Staple them together (5 pts off if not stapled).
19C-TOOLS Research Question: Is there a correlation between students’ concept map and their written explanation of a problem?Methods:1. Develop a diagnostic problem2. Build into instructional design3. Student complete as homework4. Develop coding scheme and analyze
20The Spider Monkey Problem Deep within the remote forest of Guatemala, theremains of a spider monkey were buried under anenormous mahogany tree. Although rare, jaguars havebeen spotted in this forest by local farmers. Usecoherently written sentences and clearly labeleddrawings to explain how a carbon atom in glucosecontained within the muscle cells of the spider monkeymight become part of a cell within the stomach liningof a jaguar. Provide a written description of theprocesses AND organisms the carbon atom must gothrough to cycle through the ecosystem. Include aclearly labeled drawing of the system. (Note: thejaguar does not dig up the monkey and eat theremains!)

27The Plant Adaptation Problem Problem: In this course, we haveclaimed that land plants were thefirst truly terrestrial organisms.However, most biologists contendthat the saturated soils on landwere undoubtedly teaming withbacteria, archaea, and protistslong before land plants evolved.In light of this, what does thephrase "truly terrestrial” mean?To answer this question followthese instructions:
28Task: Make a concept map using the following concepts: adaptationdispersalfitnessflowersfruitleavesphotosynthesisreproductionrootsseedsvascular tissue2. PRINT one copy for yourself then SUBMIT a copy electronically Then, using your concept map, write a short response to answer the question by explaining the problems plants had to overcome to live on land, and explain the adaptations that allowed plants to overcome those problems After you finish you short response, print it out and use a highlighter to highlight the statements (propositions) you used directly from your concept map. You should have elaborated (explained) further upon these statements in your written response. 5. Hand in hard copy of (a) concept map and (b) written, highlighted answer.
