Bellwork - slates & erasers on desks!

Hunting permits are frequently issued to help control certain populations of animals. When would a state want to issue a LOT of permits for deer hunting? How could this affect the wolf population in the area? Are deers autotrophs or heterotrophs ? What about wolves? Explain your answers.

Presentation Transcript

  1. Hunting permits are frequently issued to help control certain populations of animals. When would a state want to issue a LOT of permits for deer hunting? How could this affect the wolf population in the area? Are deersautotrophs or heterotrophs? What about wolves? Explain your answers. Bellwork- slates & erasers on desks!

  2. Announcements • Meet in M1 computer lab tomorrow for science fair proposals & research (take your 3 ring binder WITH YOU today!) • Science Café on MONDAY! Bring a snack for the class 

  3. Population Notes (adding new info today)

  4. Instructions for notes/participation When you see this pencil symbol next to something, you must write it in your notes When you see the marker, answer the question on your slate & wait for the guest teacher to ask everyone to show (No marker? Participate on scratch paper)

  5. What would happen if bacteria could reproduce indefinitely? On a slate, draw what you think the population graph would look like Exponential Growth

  6. What would happen if bacteria could reproduce indefinitely? Exponential Growth Draw a picture of an exponential growth graph in your notes

  7. What would happen if bacteria could reproduce indefinitely? In just 36 hours a single E. coli bacteriumwould replicate enough times to cover the Earth in 1ft deep of its offspring So why aren’t we covered in bacteria?

  8. What would happen if bacteria could reproduce indefinitely? In just 36 hours a single E. coli bacteriumwould replicate enough times to cover the Earth in 1ft deep of its offspring Limiting Factors! (Turn and tell your neighbor- what are the 4 limiting factors we discussed block day…) So why aren’t we covered in bacteria?

  9. World Population = 7.0 billion Human Population Clock: http://galen.metapath.org/popclk.html What eventually happens to the graph?

  10. World Population = 7.0 billion Human Population Clock: http://galen.metapath.org/popclk.html POPULATION CRASH!!!!

  11. World Population = 7.0 billion Human Population Clock: http://galen.metapath.org/popclk.html Have we reached our carrying capacity, or have we overshot it? Explain why.

  12. Human growth patterns- we use age structure graphs

  13. Human growth patterns At what ages do you see more females than males? 75-79 & 80+ What age group makes up the biggest % of Mexico’s population? Under 5 (5-9, & 15-19 are very close)

  14. Human growth patterns Will Mexico’s population increase, decrease, or stay about the same? INCREASE

  15. Human growth patterns Will Sweden’s population increase, decrease, or stay about the same? DECREASE

  16. Human growth patterns Honey, I’m hooome! Will United State’s population increase, decrease, or stay about the same? What caused this bubble of middle-aged adults? INCREASE SLOWLY

  17. Human growth patterns- add these three graphs to notes

  18. Graph & Conclusion- due TODAY! • Graph how the population of jackrabbits vs coyotes change over time (think about what kind of graph this is…) • Conclusion paragraph (complete sentences, in lab book) • When finished turn the graph into front basket • **If time- work on the Critter: Ecology Outline to get a head start on your next critter project
