Unit 1 ecology powerpoint 1 revised 2012

  1. 1. Welcome to Ecological Biology“Equipped with his/her five senses, man/woman explores the universe around him/her and calls the adventure Science.” ~Edwin Powell Hubble, The Nature of Science, 1954 “Knowledge will forever govern ignorance; and a people whomean to be their own governors must arm themselves with the power which knowledge gives.” James Madison Please read and do the following:Please pick up the 2 handouts from the front table and find a seat for now. You will be given an assigned seat shortly.Please read over the class expectations sheet and note the materials needed for class and get out a pencil or pen.
  2. 2. An Introduction:
  3. 3. So… What is Biology?Your ideas.As a science?A way of going about solving problems or answering questions about living organisms or things that impact living organisms.As a discipline of science?A set of facts and scientific theories that directly relates to the properties of life.Let’s do a demonstration that is the essence of both biology as a verb and a noun.
  4. 4. Is It Alive?How could you determine if something were alive or not?What are the characteristics of life? Are there any characteristics that are common to all living organisms?See if your table partner and you can come up with a list of characteristics common to all living organisms.
  5. 5. Make your observations by placing acheck mark by all of the characteristics you observe the object doing in the petri-dish.Now that you have made some observations…Make an argument supported by the observations that the object was alive.Make an argument supported by the observations that the object was not alive.What would you like to change about the methodology of the demonstration that you believe would improve your ability to argue whether it is alive or not?
  6. 6. So…Is it Alive?Does it matter?What did we learn from this exercise?How is this demonstration the “essence” of biology?What can you expect from biology this year?
  7. 7. Here’s what to expect in Ecological Biology AKA: Rivers BiologyAn interactive (you, me, us!) educational experience.A curriculum that focuses on the big pictures of life and the characteristics that unify all living things.A class that provides background knowledge on the basics facts and concepts of the discipline of biology while also providing a vehicle for scientific/biologic discovery through a variety of experiments and experiences.
  8. 8. Can you see the forest through the trees?Be observant!!!!!!! Things are constantly happening around you.Consider the implications of your observations.Look for the big picture, not just the details.Don’t ignore the details.See the forest, appreciate the trees 
  9. 9. ECOLOGICAL, AKA: RIVERS BIOLOGY? 1) What does the word BIOLOGY mean? Bio- “Life” ology- “study of”2) What is the most important substance to all livingthings? WATER3) Ecological/Rivers biology focuses on thestudy of life and the role of water for both theinternal and external environments in whichliving things exist.
  10. 10. Where does the river come in?We will center our study of biology on the common characteristics of living organisms. The river will provide the cords that will bind these characteristics together.The river is … a place of study, a metaphor for life, a unifying theme for the concepts we consider in our class.
  12. 12. Ecology Ecology is a relatively new branch of science that includes many of the other disciplines of scienceincluding: biology, earth science and chemistry. How is it defined? Ecology is defined as the study of the interactions of organisms with each other and with their environment.ECO- OLOGY- Study of
  13. 13. Look at these environments and consider your definition…
  15. 15. With table partners-What might some ofthese “conditions” or “factors” be?LIVING FACTORS NON-LIVING FACTORS
  16. 16. WE CALL THESE… “LIVING FACTORS” BIOTIC FACTORS- Remember bio means “LIFE” “NON-LIVING FACTORS” ABIOTIC FACTORS-Remember bio means “LIFE” and “a” is a prefix that means without or not
  17. 17. LET’S PLAY THE ABIOTIC OR BIOTIC GAME!Response cards: show me the letteryou believe the picture represents Use A for abiotic and B for = biotic
  18. 18. Fungi
  19. 19. RAIN
  20. 20. Nutrients
  21. 21. Bacteria and Protista
  22. 22. WIND
  23. 23. Animals
  24. 24. SUNLIGHT
  26. 26. Interactions between the abiotic and biotic factors in a given area. Can an ecosystem be big or small? Wet or dry? Heavilypopulated or not? Can an ecosystem include just a few living things or does it have to include lots of living things?YES! YES! YES! YES! They can be big or small. Densely populated or not. Wet or dry. Indoors or outdoors.
  27. 27. Examples of ecosystemsinclude the following:
  28. 28. Aquatic
  29. 29. Terrestrial
  30. 30. Large
  31. 31. Small
  32. 32. Natural
  33. 33. Artificial
  34. 34. How do the abiotic and bioticfactors shape the appearance andfunction of an ecosystem?
  35. 35. The abiotic and biotic factorswithin an ecosystem play amajor role in determining manyaspects of the ecosystem. One example of this is that the abiotic and biotic factors determine the biodiversity of the ecosystem. Consider the two words that make up the term biodiversity, (bio=? and diversity=?) what do you think this term means?
  36. 36. BiodiversityThe number of differenttypes of living organisms inan ecosystem.
  37. 37. The greater the BIODIVERSITYthe healthier the ecosystem may be. If the abiotic conditions Then there will be are favorable in an more biotic factors ecosystem
  38. 38. TRY THESE:1. Name 3 abiotic factor that could have a major effect on biodiversity of an ecosystem.2. Name 3 biotic factors that could have a major effect on biodiversity of an ecosystem.3. Determine whether or not the following slides have HIGH biodiversity or LOW biodiversity. Use thumbs up for relatively high biodiversity and thumbs down for low biodiversity.
  39. 39. Tropical Rainforest 
  40. 40. Tundra
  41. 41. Coral Reef 
  42. 42. Some deserts
  43. 43. AN ANT HILL
  44. 44. How might we/scientists be able todetermine the biodiversity of this area?
  45. 45. Our own N.E. Illinois area is(or at least once was) known forwhat dominent type of ecosystem? Illinois is nicknamed the: Prairie State.
  46. 46. For our problem/question wewill consider the following:How does the biodiversity of plants (producers) in a native grassland (Prairie) compare to that of a introduced grassland such as that planted by European settlers that now covers many of our landscapes and lawns in the Northbrook area?
  47. 47. Large ecosystems with a fairlyconsistent set of abiotic and biotic factors are known as biomes.  Each biome is defined primarily by its abiotic factors of climate and location on the planet. Some biotic factors also play a role in its definition.  Biomes can be either aquatic or terrestrial.
  48. 48. Can you and your table partner thinkof some common types of biomes?GRASSLANDS TEMPERATE FORESTS SAVANAS DESERTS
  49. 49. You can read about the many different types of biomes in your text.Consider what abiotic factors might influence what type of biome occurs in different parts of the earth.Consider how those abiotic factors might influence the types of organisms that live there with regards to their ability to survive, reproduce and be successful.
