What is one thing that frightens you about finals? What can you do to get a better grade besides study?
What was one of the greatest parts of your thanksgiving break? (please don’t say sleep)

3. 25.2 KEY CONCEPT Matter cycles in and out of an ecosystem.

4. Water cycles through the environment.
The hydrologic, or water cycle, is the circular pathway of water on Earth.
Organisms all have bodies made mostly of water.
precipitation
condensation
transpiration
evaporation
water storage
in ocean
surface
runoff
lake
groundwater
seepage

5. As students watch the video, they will take notes looking for:
Water cycle
As students watch the video, they will take notes looking for:
1. The three states of water: liquid, solid, gas.
2. Definition of the terms: evaporation, runoff, seepage, transpiration, condensation, precipitation

6. Why do you think the water cycle is so important to us? Be specific!
Tuesday 11/29/2016
Before you finish the first question, start downloading the free app on your phone: “stop motion studio”.
Why do you think the water cycle is so important to us? Be specific!

7. Things needed in your stop motion video for full credit:
Water shown at least once in all three states:
Liquid
Solid
Gas
All of these words need to be used in your video at least once:
Seepage
Runoff
Evaporation
Condensation
Precipitation
Transpiration
Groundwater

9. What are some sources of carbon on earth?

What are some sources of carbon on earth?
Explain what seepage is and how it relates to water.

10. Elements essential for life also cycle through ecosystems.
A biogeochemical cycle is the movement of a particular chemical through the biological and geological parts of an ecosystem.

11. Oxygen cycles indirectly through an ecosystem by the cycling of other nutrients.
respiration
carbon
dioxide
photosynthesis

12. Carbon is the building block of life.
Carbon cycle moves carbon from the atmosphere, through the food web, and returns to the atmosphere.
Fossil fuels (oil, gas) emit carbon back into the atmosphere
fossil fuels
photosynthesis
decomposition
of organisms
respiration
carbon
dioxide
in air
combustion

13. NITROGEN CYCLE
Takes place primarily underground

14. Nitrogen fixation: nitrogen gas (N2) ammonia (NH3)
Bacteria will “fix” or “change” it into a usable form for plants
- bacteria live freely in soil or
- on nodules of roots of some plants such as beans and peas (legumes)
Nitrogen gas (N2) converted  Ammonia (NH3)  converted to Ammonium (NH4)  energy source for bacteria

15. Nitrification
Bacteria change ammonium  Nitrates NO3-  taken up by plants  convert to Proteins -Denitrifying bacteria use nitrates as a source of oxygen  release nitrogen gas BACK into atmosphere

16. Atmospheric Nitrogen fixation
Lightening breaks apart nitrogen molecules

17. Ammonification: Role of Bacterial Decomposers
Decomposers break down
Animal excretions
Dead animals or plants
Nitrogen from this matter  returned to soil as ammonium

19. animals

ammonium

nitrogen-fixing
bacteria in soil
nitrates
nitrites

20. Nitrifying bacteria change the ammonium into nitrate .
Ammonia released into the soil is transformed into ammonium (Ammonification).
Nitrifying bacteria change the ammonium into nitrate .
Nitrogen moves through the food web and returns to the soil during decomposition.

21. What are some sources of nitrogen on Earth?
Thursday 12/3/2015
What are some sources of nitrogen on Earth?
What is nitrification? What is nitrogen fixing?

22. Think! Turn and talk to your partner to answer!
Where does the source of nitrogen come from for animals?
Where does the source of nitrogen come from for plants?
What form of nitrogen do plants commonly use?
What is nitrogen fixation?
Why might farmers use legumes such as peas to improve the nitrogen levels in their soil?
Plant matter 2. decomposers, bacteria 3. nitrates
4. The process that changes N-gas into a usable form for plant material 5. Legumes have nodules containing nitrogen-fixing bacteria which can increase N-levels in the soil without adding fertilizer

23. What are the two main processes used in the Carbon- Oxygen cycle?
After watching the videos and taking notes, create a T-Chart and list the sources of carbon and oxygen to show how they are each cycled through the environment. Collaborate with your partner!
CARBON OXYGEN

Write down each letter and label/describe the step.
What step is missing that is similar to A?

26. Carbon Cycle Nitrogen Cycle
Make sure you show all the steps including:
At least 3 different types of combustion
At least 2 different sources of respiration
Two different plants using photosynthesis
Explain and show how fossil fuels contribute to the cycle
Nitrogen Cycle
Make sure you show all the steps including:
