  6. October 3rd Bell Ringer: What is the role of a decomposer within the Carbon Cycle? Objectives: *Hold on to the Carbon Cycle Simulation Sheet • BioGeoChemicalCycles YouTube video **Please take out a sheet of paper for notes. • Read ch 3-3 p83-89 and complete the guided reading. *If not completed in class, please come to office hours to use the book.

  7. October 6th Bell Ringer: How are the chemical equations of photosynthesis and respiration related? Objectives: • Review 3-4 guided reading • Carbon Forest Activity • Carbon Molecule Journey Summary *Today is the last assignment for quarter 1. All missing work due by FRIDAY, 10/10!!

  8. Carbon Forest Activity • All life is based on the element carbon. • Carbon is the major chemical component of most organic matter, from fossil fuels to the complex molecules (DNA and RNA) that control genetic reproduction in organisms. • Yet by weight, carbon is not one of the most abundant elements within the Earth's crust. • In fact, the lithosphere is only 0.032% carbon by weight. In comparison, oxygen and silicon respectively make up 45.2% and 29.4% of the Earth's surface rocks.

  9. Carbon is stored on our planet in the following major sinks: • as organicmolecules in living and dead organisms found in the biosphere • as the gascarbon dioxide in the atmosphere • as organic matter in soils • in the lithosphere as fossil fuels and sedimentary rockdeposits such as limestone, dolomite and chalk • in the oceans as dissolved atmospheric carbon dioxide and as calcium carbonateshells in marine organisms.

  10. The Carbon Cycle

  11. The Procedure • There are six stations label around the room. • You will be randomly placed at one of the stations. • Each student rolls the die or choose a number between 1 and 6, and then read the statement at their station corresponding to that number. • Write on the lab sheet the current station, what happens to you based on their number, and where you will go next. • When I call out “cycle,” you should go to the next station as directed on the card. • If the directions have you stay at the same station, then you should either roll the die again or choose again a number between 1 and 6. • We will repeat steps about ten more times or until most students have cycled through Tree Station at least once.

  12. My Journey as a Carbon Atom Write a brief story from a carbon atom’s point of view that describes the journey they just took through the carbon cycle. For example, a story might start as “I was a carbon atom in a tall tree. One day a fierce storm came, and knocked the tree over. It lay for a long time on the forest floor. As it decayed, I was released into the atmosphere….”

  13. Further Thought and Discussion Discuss the following: • At which station did you spend the most time? At which station did you spend the least time? • While each of your journeys was different, was there anything similar about them? • At which stations can carbon be stored? At which stations is carbon released into the atmosphere? • What are the different paths carbon might take after becoming a tree? Which paths release carbon quickly into the atmosphere, and which store carbon for a long period of time? - How does the carbon cycle help us understand the relation between forests and global climate change?

  14. October 7th Bell Ringer: What does the law of the conservation of matter state? Objectives • Carbon molecule journey summary due • Pass Back Graded Assignments • Discuss Important Dates • Nitrogen pre lab activity: p87 • Continue the Biogeochemical Cycle Outline: Nitrogen is “C” on your outline. • Nitrogen Cycle PowerPoint **

  34. Water Cycle 1. Draw a water cycle and include the processes of transpiration, precipitation, evaporation and condensation. Evaporation (Transpiration via plants) -> Condensation -> Precipitation -> Repeat 2. Describe transpiration – the release of water vapor by plants through their leaves 3. Describe precipitation – water returns from the atmosphere; ie: rain, snow, sleet, hail

  35. Water Cycle Continued…. 4. Describe evaporation - water moves from bodies of water and moist soil into the atmosphere; the conversion of liquid to a gas 5. Describe condensation- a change in state from a gas to a liquid 6. List several ways humans negatively affect the water cycle? Clearing plants = increase erosion, runoff, increase evaporation and decrease transpiration Spreading water onto fields = deplete surface & groundwater Release of pollutants = acidic precipitation Industry and irrigation = depletes groundwater

  36. Carbon Cycle 7. Describe pure carbon. (Color, state of matter) – black, solid 8. What carbon compound is necessary for photosynthesis? Carbon dioxide (CO2) 9. What two substances are produced by photosynthesis? Oxygen and Sugar 10. How are humans contributing to the overload of carbon dioxide in the atmosphere? By extracting and burning fossil fuels; cutting and burning of forests 11. Describe how carbon dioxide and other greenhouse gasses affect the temperature of Earth. Protects the earth from the bitter cold of space; keeps the earth warm

  37. Carbon Cycle Cont… 12. Describe the ways carbon dioxide gets into our atmosphere. Burning of wood and fossil fuels; cellular respiration; human exhaling 13. Describe the ways carbon dioxide is removed from our atmosphere. Photosynthesis, sediments (limestone and fossil fuels), oceans 14. What is happening to the overall amounts of carbon dioxide in our atmosphere? Increasing amounts; more carbon being released into atmosphere than what can be absorbed by plants

  38. Nitrogen Cycle 15. What molecules in our bodies require nitrogen for their production? Essential for proteins which make DNA and RNA 16. What state of matter is atmospheric nitrogen? gas 17. What must happen to atmospheric nitrogen before it can be used as a nutrient by an organism? Nitrogen fixation must occur by a bacteria before it can be used. 18. How do humans get the nitrogen they need? Humans must eat plants directly or eat plant-eating animals.

  39. Phosphorus Cycle 19. What molecules in our bodies require phosphorus for their production? Cell membranes, DNA and RNA 20. Why is phosphorus a limiting nutrient in so many ecosystems? Because most of it is bound up in rock. 21. What are common sources of phosphorus? Rocks, soil, sediments and oceans.

  40. GENERAL 22. What affect does fertilizer have on nutrients in our ecosystem? Can increase the growth of algae, leading to eutrophication, hypoxia or a dead zone. 23. Define Eutrophication and what causes it. An overgrowth of primary producers (plants/algae) causes the amount of oxygen in a body of water to decrease, leading to hypoxia, eventually could lead to a dead zone. 24. What is the most abundant element in our atmosphere? Nitrogen 25. Define the Law of Conservation of Matter. Matter can be neither created nor destroyed, simply transformed.

  41. October 24th Bell Ringer: copy the statement Ecology is the study of the ecosystem. Objectives: • Biogeochemical Test • LAST DAY to TURN IN Cycle Packet assignments!!! Begin The Study of Ecology Read p101-103 – Create a vocab chart: TERM -Definition- Use in a Complete Sentence

  42. October 27th Bell Ringer:NEW SHEET Define species (p101) and provide an example. Objective: 1. Ecosystem PP notes: Number paper 1-29 2. Outdoor Classroom pre-Lab (we will be going outside tomorrow, please dress appropriately) *eco success 3. Complete ch 4-1 (p100-103) vocab chart – due tmrw

  43. October 28th Bell Ringer: What is a population? Objective: • Review Outdoor Classroom Pre-Lab • Outdoor Classroom Lab *Place stapled Ecology Packet (Ch 4-1 Vocab Chart/Ecology PP notes/Outdoor Lab) into bell ringer tray.

  44. Outdoor Classroom pre-Lab • A community is all of the populations within a particular area. • An ecosystem is all of the living things and their physical environments within a particular area • A population are members of a species that live in the same area at the same time. • An abiotic factor is parts of the ecosystem that has never been living. • A biotic factor is parts of the ecosystem that are living or used to be living.

  45. 6.c. Ecological Succession Ecosystems undergo change over time. These changes are known as succession. For example, a forest that is clear cut will develop into a forest again if enough time is allowed for natural processes to occur.

  46. 6. a. Primary succession Primary ecosystem succession is when a community first forms in a newly created or exposed area such as a sand dune or bare rock surface, lava flow, or a new lake created by flooding. In a sense, this is as if the community forms from a “clean slate” ecologically speaking.

  47. 6. b. Secondary Succession Secondary succession is when a community was disturbed by human or elemental forces. This form of succession tends to be much more rapid as some of the vital elements such as soil, nutrients and seeds are already present at the location at least to some extent. An example of this kind of succession is a forest recovering from a major forest fire or logging event.

  48. Outdoor Classroom pre-Lab cont. 7. A resource is anything an organism needs: • Nutrition • Shelter • Breeding sites • Mates • Oxygen/water 8. A habitat is the specific environment in which an organism lives.

  49. October 29th Bell Ringer: Explain the difference between abiotic and biotic. Provide an example of each. Objectives: 1.“How much is an ecosystem worth?” Project – due on Friday! *Ecosystem Quiz on Friday, October 31st!
