SEVEN MAJOR BIOLOGICAL THEMES
Organization On Multiple Levels The natural world has inherent structure and organization; Nature is NOT random This organization occurs on multiple levels of complexity
Energy Flow 1 st Law of Thermodynamics = Energy cannot be created or destroyed, only changed Energy flows through living systems on multiple levels
Brevoortia tyrannus (Atlantic Menhaden)
Key To Ocean Ecosystems Critical “small fish” linking algae and larger, carnivorous fish in food chain
INTERDEPENDENCE OF LIFE All lifeforms are interdependent to some degree Life cannot exist in the absence of other lifeforms/species Organisms rely on others for food, nutrients, water, shade, protection and other needs
Ants & Acacias
Wolves & Willows
CONTINUITY WITHIN CHANGE As species evolve, certain traits are changed, while other vital traits are retained over the course of time. Populations undergo continuity, not individuals
UNITY WITHIN DIVERSITY Organisms that may not necessarily be closely related may exhibit similar structures or features The reasons for these structural similarities are similar needs created by their environments
UNITY WITHIN DIVERSITY
FUNCTION DICTATES FORM The form of structures in living organisms serve specific purposes that aid in the organism’s survival Evolution does not retain superfluous or unnecessary structures The Philtrum
Villi vs. Appendix
HOMEOSTASIS The tendency of organisms and populations to keep certain aspects of their composition the same Often as a means for combating entropy (tendency towards disorder in nature)
Different Modes of Thermoregulation
Populations Exhibit Homeostasis
Seven Themes Visual Essay Purpose: To visually represent each of the seven biological themes/truisms and to articulate your understanding of each theme Method: Visual presentation via Google Docs, collaborative commentary by other groups, rebuttal/articulation of actual themes selected
Part One: Construction Go to your Gmail account and access the Seven Biological Themes Visual Essay Presentation Template for your lab group. NOTE: You have been invited to comment on another group’s presentation. HOWEVER, you should not construct or add to their original seven slides. Review the seven biological themes on the first page of this document. Search the web for seven images that illustrate each of the seven themes (49 total images) Place images that illustrate the same theme on the same slide. Scramble the slide order of slides 2-8 so that the first slide is not necessarily the first biotheme from the handout.
Part 2: Commentary When all members have contributed to the construction of the presentation, the four members from the invited group may view the presentation On the appropriate comment slide, the invited group should suggest which theme they think is being illustrated by each of the original group’s seven selected images
Part 3: Rebuttal/Articulation of Original Intended Theme Once the invited group has completed their suggestions on the comment slides, the original creators of the presentation should view these comments. In confirmation or rebuttal of these comments, the original group should write what their original biotheme choice was for each of the original seven slides (slides 2- 8) and why those images were chosen.
Assessment Assessment Rubric: Part One: All Seven Content Items Not Content is not varied and/or appropriate Presentation not posted by deadline Presentation not posted -3.0 Part Two: All seven content items not explained in essay Reasoning is vague or Essay not submitted to inbox by deadline Essay portion not submitted -3.0 Part Three: Missing any of three reviews Reasoning is vague, inappropriate or absent Reviews not submited by deadline Reviews not submitted -1.0 Part Four Missing replies to any of three reviews Reasoning is vague, inappropriate or absent Reviews not submited by deadline Reviews not submitted -1.0 Note: While students will be working on this in a collaborative fashion, students with significantly diminished input may receive deductions up to 20%.
Reviewing The Work Once all of the Glogs are posted tonight, you may start to review any three (3) of the Glogs. For each Glog, pick one image/content item that you think clearly demonstrates a particular biotheme. Access the Seven Themes… Google Document and briefly (2 sentences per item) explain your understanding of the content item in one of the three spaces underneath that person’s submission space on the document If all three of the spots are already filled for that person’s Glog, find a different Glog and review/report on that one. This task should be completed by midnight on Monday September 3 rd, 2012
Responding To the Reviews Once three reviews/comments have been posted on your submission space (on 9/3/12), you will respond to each of the comments. For each content item of your Glog that was reviewed, provide YOUR view/intent for that item. You may use some of the same explanations that you submitted to your instructor on Thursday morning. This task should be completed by 9/7/12.
