1. Tuesday September 29th In Notebook:

2. Today’s Learning Targets Agenda: 1.Finish Levels of Organization Poster 2.Show off poster! 3.Start Biogeochemical Cycles

3. What’s a cycle? What is your understanding of a cycle? How have you heard it used in science and in everyday life?

5. Biogeochemical Cycle bio- geo-chemical = The exchange of matter (anything that takes up space and has mass) through the biosphere (atmosphere, land, and water)

6. What is the Carbon Cycle? GOAL: Draw the carbon cycle using the information given to you. Work with your assigned group to answer the questions on your worksheet. Rotate to go to each station when told to switch! On the back of your worksheet draw the carbon cycle using your answers to guide you. GROUP DISCUSSION, BUT INDIVIDUAL WORK.

9. Wednesday September 30th In Notebook: What is your current understanding of the water cycle?

10. Today’s Learning Targets Agenda: 1.Helpful Notes 2.Finish Carbon Cycle Stations 3.Cycle Notes 4.HEADS UP: OUTSIDE TOMORROW!

11. But first… helpful vocab Law of Conservation of Mass – matter can be changed from one form into another, but the total amount of mass in universe remains constant Reservoirs/Sinks - places where matter and nutrients are stored

12. Finish Stations Go to where you ENDED yesterday. We will rotate to the next one as a class. 5 minutes at each station.

13. Station 1: Introduction to Carbon Cycle Carbon moves through these processes: 1. 2. 3. 4. Photosynthesis - carbon moves from the environment into living things Respiration - carbon moves from living things back to the atmosphere Decomposition - carbon moves from dead organisms back to the environment Combustion - burning fossil fuels releases carbon back into the atmosphere

14. Station 2: Ocean Carbon Cycle Additional Info: Carbon can diffuse back into atmosphere as water warms after upwelling. Carbon can be brought to deep ocean by decay/decomposition of organisms.

15. Station 3: Soil Carbon Cycle ALL ON THE PINK SHEET

16. Station 4: Terrestrial Carbon Cycle Woody plants can sequester carbon – pull carbon out of circulation Plants take in carbon dioxide and give away oxygen. Animals breathe in oxygen and give away carbon dioxide. They depend on eachother!

17. Station 5: Atmospheric Carbon Cycle Form of carbon in atmosphere: CO 2 (carbon dioxide) and CH 4 (methane gas)

18. Station 5: Atmospheric Carbon Cycle

19. Time to draw the carbon cycle!

21. Thursday October 1 st In Notebook: No Question of the Day. Be ready to go outside after attendance.

22. Today’s Learning Targets Agenda: 1.Ecological Observations in Bunker Hills Regional Park

24. Friday October 2 nd In Notebook: Define biogeochemical cycle. What biogeochemical cycles should you be able to label and explain in this class?

25. Today’s Learning Targets Agenda: 1.Finish drawing carbon cycle 2.Notes 3.HOMEWORK?!

26. Time to draw the carbon cycle!

27. Water Cycle

28. Processes of Water Cycle Evaporation - liquid water becomes a gas Transpiration - liquid water evaporating off plants Condensation - water changing from gas to liquid Precipitation - water falling to Earth from the atmosphere

29. Processes continued… Run-off - water running over the land that collects in the oceans, lakes, or rivers Infiltration - water seeping into the ground that provides water for the soil, streams, rivers, and oceans Ground water - stored in underground caverns and porous rock

32. Nitrogen Cycle

33. Nitrogen in the atmosphere is UNUSABLE Some bacteria can perform nitrogen fixation - capturing nitrogen in atmosphere and converting it into a form that is usable by plants. Animals get nitrogen from eating plants. Nitrogen is also fixed by the energy in lightning strikes Nitrogen enters soil when animal urinates/dies Nitrogen is taken out of soil by plants converting it into proteins or by Denitrification - nitrogen is converted back to gas by some bacteria in the soil

35. Future Nitrogen Cycle Excess nitrogen can cause eutrophication - nutrient over enrichment in water. Can cause harmful algal blooms, massive fish-kill events, and species shift. Scientists, farmers, and policymakers are encouraged to decrease fertilizer use while safeguarding agriculture Use new farming methods Maintaining wetlands

36. Homework for Monday: Research the impact that humans have on the carbon cycle, the water cycle, AND the nitrogen cycle. 2 for each cycle …. 6 TOTAL! Write them down in your notebook!
