CARBON CYCLEnotes

AtmosphereCO2 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 off CO2

Geosphere

Lithosphere - 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 them releases CO2

Hydrosphere

carbonic acid forms when CO2 of the atmosphere dissolves in water

pH scale: low number = 1 (acidic), 7 (neutral, H2O), high number = 14 (basic)

Ocean AcidificationYes, it dissolves coral reefs !

Sun’s energy passes through the windshield.

Energy (heat) is trapped inside the car & cannot pass back through the

windshield, causing the warm up.

Greenhouse Effect

Don’t write this, THINK about it !

You already know what it is:

Should I leave my dog or baby in the

car?

the Greenhouse Effect

The natural warming of Earth’s surface & lower

atmosphere due to trapped heat energy.

What are the “other gases” that cause the greenhouse effect?

Greenhouse Gases:

CO2 = carbon dioxide

THINK ABOUT IT

Hint: Venus has a very thick atmosphere of carbon dioxide (CO2)

Why is Venus the hottest planet in the solar system even though Mercury is a lot closer to the Sun?

Answer:

the extra CO2 causes the greenhouse effect to be stronger by trapping more heat

Venus has an average surface temperature hot enough to melt lead!

Urban Heat IslandUrban area that has a consistently higher temperature than the

surrounding rural areas due to the trapping of heat by buildings, concrete, & asphalt.

Ways to reduce it:

• Tree cover / canopy• Green rooftops / rooftop gardens

• “Rubberized” Asphalt• Permeable paving materials

Permeable pavers reduce the Urban Heat Island effect.

Possible Aim/s: 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.

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.

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.

•1,430 lbs. CO2 pollution avoided •$30 saved

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.

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 RevisionUse 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.
