2. Fun Facts about Carbon: (you don’t have to know this)
CARBON CYCLE
Atoms
Molecules
Element Carbon
Carbon Compounds
diamond (C)
graphite (C)
ashes
carbon dioxide (CO2)
calcium carbonate (CaCO3)
sugar / glucose (C6H12O6)
organic compounds (fats, protein, etc)
hydrocarbons (long chains of carbon & hydrogen)
fossil fuels (gas, oil, coal) are hydrocarbons
Fun Facts about Carbon: (you don’t have to know this)
Diamonds
Graphite

3. CARBON CYCLE notes Atmosphere Biosphere Geosphere Hydrosphere
CO2 gas (<1% of all gases), delicate balance 
Bill Nye, Cows & Methane video
Biosphere
Photosynthesis – plants (producers) take in CO2, make sugar (food), & give off O2
Respiration – living things (organisms) break down sugar (food) & give off CO2
organic decay – fungi & bacteria (decomposers) break down living remains & give of CO2
Geosphere
Lithosphere is largest depository of carbon (in rocks), volcanoes release CO2, deposition (into rock), weathering (into CO2 gas), carbon sediments buried over long periods can become
fossil fuels (coal, oil)
burning fossil fuels releases CO2
Hydrosphere
carbonic acid forms when CO2 in the atmosphere combines with water (fresh & sea water)
pH scale: low number= 1 (acid, acidic), 7 (neutral, H2O), high number= 14 (base, alkaline)

7. Greenhouse Effect You already know what it is:
Sun’s energy passes through the windshield.
Don’t write this, THINK about it !
Energy (heat) is trapped inside the car & cannot pass back through the windshield, causing the warm up.
Should I leave my dog or baby in the car?

8. Greenhouse Effect
The natural warming of Earth’s surface & lower atmosphere due to trapped heat energy.

10. ALBEDO
ability of a surface to reflect light & heat energy back into the atmosphere & space
Low
Medium
High
anything darker / black
anything middle spectrum / green or brown
anything lighter color / white
rooftops, blacktops, darker soils
plants, trees
ice, snow, glaciers, clouds

11. Urban Heat Island
Urban area that has a consistently higher temperature than the surrounding rural areas due to the trapping of heat by buildings, concrete, & asphalt.

12. Permeable paving materials
Ways to reduce it:
Tree cover / canopy
Green rooftops / rooftop gardens
“Rubberized” Asphalt
Permeable paving materials

13. Permeable pavers reduce the Urban Heat Island effect.

15. Possible Aim/s: Do Now:
a. How does global warming work? b. What’s up with global warming? c. How does carbon dioxide emission affect global warming?
Do Now:
Write at least three questions
about the diagram/picture.

16. GLOBAL WARMING
is the increase of the Earth’s average surface temperature due to a build-up of greenhouse gases in the atmosphere.
CLIMATE CHANGE
is a broader term that refers to long-term changes in climate, including average temperature and precipitation.

17. Effects of Global Warming
Rising Sea Level
Increased Temperature
Habitat Damage and
Species Affected
Changes in Water Supply

18. What’s the proof that global warming is taking place?

23. Global Atmospheric Concentration of CO2

24. Environmental problems - the greenhouse effect
Greenhouse gasses absorb some of the heat and trap it near the earth's surface, so that the earth is warmed up. This process, commonly known as the greenhouse effect.
The amount of heat in the troposphere depends on concentrations of atmospheric greenhouse gasses and the amount of time these gasses remain in the atmosphere. The most important greenhouse gasses are carbon dioxide, CFC's (Chlor-Fluoro-Carbons), nitrogen oxides and methane.

Fuel-Efficiency

29. What can you do to help solve the problem?

30. Simple Things To Do Turn off your computer or the TV
when you’re not using it.
Take shorter showers. Heating water uses energy.
Keep rooms cool by closing the blinds, shades, or
curtains.
Turn off the lights when you leave a room.
Use compact fluorescent bulbs.

31. Be Bulb Smart—Use CFLs What’s the difference? Compact Fluorescent
Incandescent
500 lbs. of coal
1,430 lbs. CO2 pollution avoided
$30 saved

32. Simple Things To Do Dress lightly when it’s hot instead of turning up
the air conditioning. Or use a fan.
Dress warmly when it’s cold instead of turning
up the heat.
Offer to help your parents keep the air filters on
your AC and furnace clean.
Walk short distances instead of asking for a
ride in the car.
Plant a tree.
Recycle.

33. Phase 3- Reflection, Feedback and Revision
Phase 2- Activity
a. Designing and Constructing The Temperature Reader
b. Using the temperature reader in an experiment.
c. Fill out the worksheet as you perform the experiment.
Phase 3- Reflection, Feedback and Revision
Use the rubric to evaluate the temperature reader and laboratory sheet. Then switch with other groups and let them do the same. Revise the temperature reader and lab worksheet as needed.
