biology window panes for Tuesday 9-7-2010
Biology terms:Window pane terms 2:1. Photosynthesis- the process of making food (glucose) using sunlight.2. Autotrophs- organisms that make their own food using photosynthesis.3. Heterotrophs- organisms that have to consume other organisms to obtain the energy they need to survive.4. Consumers- organisms that have to eat other organisms5. Producers- organisms that make food for other organisms6. Individual- one member (organism) of a particular species.7. Population- all of the members of a particular species8. Community- all of the different types of living organisms in a given area9. Ecosystem- all of the living and non-living things in a given area10. Omnivore- organism that eats plants and animals for its energy needs11. Herbivore- organism that only eats plants for its energy needs12. Carnivore-organism that only eats animals for its energy needs13. Detritivore- organism that eats dead things for its energy needs14. Decomposer- organism that breaks organic matter down into its basic elements.15. Biomass- the weight of organic matter in a given area.16. Abiotic factors- non-living things that exist and play a role in an organism's environment.17. Biotic factors- living things in the environment18. Symbiosis- a close relationship between two organisms19. Limiting factors- anything that contributes to the survival and reproduction of an organism, therefore if there is not enough of it, the population will decrease. (water, food, habitat are examples)20. Carrying capacity- the maximum amount of organisms that can live in an area. (note: this is usually determined by the limiting factors in an environment)

HONOR STUDENTS: Science Friday Questions to answer as you listen!
“Modern Extinctions”
(will take @45 min to listen to)
http://www.sciencefriday.com/program/archives/201005141
1. How many conservation goals were set to be met by 2010?
2. Define: Invasive species
3. How many were met?
4. What number extinction do scientists believe we are leading up to?
5. What is the extinction rate of the lizards in Mexico?
6. What was the sample size of the Mexican lizard population (how many sites?)?
7. Why is a 2 or 3 degree difference do damaging?
8. Why can’t the lizards adapt to the new temperature?
9. What part of the amphibian population is in decline in Yellowstone National Park?
10. When and why did the human population begin to increase dramatically (exponentially)?
11. How did humans manage to keep biological diversity stable until recently (past decade or two)?
12. “ Ecosystem services” are supplied by what type of organisms?
13. Give an example of an ecosystem service:
14. What type of organism can live for a hundred years in the wild?
15. The Chytrid fungus affects what part of an amphibian?
16. How many species of amphibians have been affected (population in decline or extinct now) by this fungus?
17. What climate does the Chytrid fungus enjoy?
18. Learning about the things that stress our ecosystem can help us to do what better?
19. What percentage of the Earth’s terrestrial surface is still considered wild or undeveloped?
20. What qualifies that land as being wild?
21. What percentage of the wild land is already protected land?

First window pane list
Here's your first homework assignment! Due Friday8/27
Go to my blogspot and print off your first list of window panes, bring in your list and show it to me on Friday!
First word list: (only 10 this time, next time there will be more)
Test on Scientific method Wednesday 9/1
Honors- First NPR assignment due Friday 9/3

Go to my blogspot and print off your first list of window panes, bring in your list and show it to me on Friday!
First word list: (only 10 this time, next time there will be more)
1.Observation- when you notice things about the world around you using your senses.
2.Hypothesis- Your opinion of why a certain thing is ocurring, an educated guess based on previous experience.
3. Data- Information you collect when running an experiment.
4. Experiment- an organized, controlled way of testing your hypothesis.
5.variable- something that can change in quantity or quality.
6. Independent variable- something you have control over and alter during an experiment. It's the thing you are testing! ONYL ONE variable can be tested at a time.
7. Dependent variable- the thing being measured in an experiment! It is the variable that changes as a result of you manipulating the independent variable.
8. Constants or Controlled variables- these are the things that have to remain unchanged and stable throughout your experiment. If they are altered at all then your experiment is not valid.
9. control group- the sample in your experiment that is not being exposed to the independent variable. This group lets you know whether the results you obtain from your experiment are from the independent variable or simply the result of something in the environment.
10. test group- the sample in your experiment being exposed to the independent variable. Bigger is Better! You want a test group to be as large as possible to make sure that the results you get are true and not a fluke.
These window panes are due Tuesday 8/31
Test on Scientific method Wednesday 9/1
Honors- First NPR assignment due Friday 9/3
