The Raven
by Edgar Allan Poe (1845)
Once upon a midnight dreary, while I pondered, weak and weary,
Over many a quaint and curious volume of forgotten lore,
While I nodded, nearly napping, suddenly there came a tapping,
As of someone gently rapping, rapping at my chamber door.
" 'Tis some visitor," I muttered, "tapping at my chamber door;
Only this, and nothing more."
Stanza 2
Ah, distinctly I remember, it was in the bleak December,
And each separate dying ember wrought its ghost upon the
floor.
Eagerly I wished the morrow; vainly I had sought to borrow
From my books surcease of sorrow, sorrow for the lost
Lenore,
For the rare and radiant maiden whom the angels name
Lenore,
Nameless here forevermore.
Stanza 3
And the silken sad uncertain rustling of each purple curtain
Thrilled me---filled me with fantastic terrors never felt
before;
So that now, to still the beating of my heart, I stood
repeating,
" 'Tis some visitor entreating entrance at my chamber door,
Some late visitor entreating entrance at my chamber door.
This it is, and nothing more.”

Our theory on how he died
Carbon monoxide poisoning
Look at the portrait carefully.
The drooping right eye and
mouth are symptomatic of CO
poisoning.

Chemistry of CO Detectors
Chemistry of CO Detectors
Types of CO detectors:
• Biomimetic - They mimic the action of
hemoglobin
• Semiconductor - Uses electronics to monitor
CO levels
• Electrochemical - Uses a redox reaction to
detect CO levels
Biomimetic
Infrared light
Hemoglobin-like gel
Infrared sensor,
connected to alarm
http://www.chemistry.org/portal/a/c/s/1/feature_ent.html?id=04dd47d40b8211d7f0856ed9fe800100
Biomimetic
Carbon Monoxide
http://www.chemistry.org/portal/a/c/s/1/feature_ent.html?id=04dd47d40b8211d7f0856ed9fe800100
Biomimetic
Carbon Monoxide binds to the gel.
This causes the gel to turn dark.
http://www.chemistry.org/portal/a/c/s/1/feature_ent.html?id=04dd47d40b8211d7f0856ed9fe800100
Biomimetic
The more carbon monoxide
binds to the gel, the darker it
becomes. This will eventually
block the infrared light, which
sets off an alarm.

The more
electrons that are
in the sensor, the
lower the
resistance.
At a certain
resistance, the
alarm will go off.

Recommendations on Carbon
Monoxide Hazard Reduction
• If you smoke, quit
• Test/check your CO monitor annually (never remove the batteries)
• Install CO monitors on all living levels, especially sleeping areas
(within 10 feet of bedrooms doors)
• Provide good airflow around heating appliances
• Make sure that gas appliances like dryers vent outside
• Never use a barbecue or generator in the home or closed garage
• If you smell gas or a detector goes off, exit the building and call 911
• Make sure natural gas, oil, wood, and kerosene appliances are in
good working order
• Never use an oven or stove to heat your home
• Have heating system and chimneys cleaned and inspected annually

Student “Poe-ster” Session
Give each pair of students a piece of poster paper, and
a box of coloring pencils.
Randomly hand them a topic from the following list:
– Physical Properties of CO
– Symptoms and Treatment of CO poisoning
– Physiology of CO transport
– Sources of CO
– Detection and Chemistry of CO Detectors
– Recommendations on CO Detectors in the home
– Use of CO
(Use folders with one topic on each folder, there may be more
than 1 or 2 groups working on the same topic)
Every “Poe-ster” should show:
• Title of Sub-topic
• Student names
• A graphic to help convey
the topic
• A poem to convey
information about the topic

“Poe-ster” Session
• Have students present their “Poe-ster” and then post
it on the wall.
• Students should read their poem, and interpret it for
their classmates.
A poem about Hemoglobin
by Roald Hoffman
Nobel laureate in Chemistry
This biconcave bialy platelet of the erythrocyte,
the red heart of the blood, holds the oxygen
carrier, hemoglobin.
Four coiled polypeptide chains, four subunits
changing pairwise twice in the fetus to let it
soak up placental O2 steadily.
Each chain a globular protein, juxtaposed
twining of helical segments, predestined
kinks, sequences of amino acids alike in
sperm whale and horse…
The last stanza from
“The Raven”
And the raven, never flitting, still is sitting, still is sitting
On the pallid bust of Pallas just above my chamber door;
And his eyes have all the seeming of a demon's that is dreaming.
And the lamplight o'er him streaming throws his shadow on the
floor;
And my soul from out that shadow that lies floating on the floor
Shall be lifted---nevermore!
Modified last stanza from
“The Raven”
And the raven, never flitting, still is sitting, still is sitting
On the palladium bust by the furnace door
And his eyes have all the seeming of a CO detector that is
gleaming
And the furnace gases streaming CO2 and nothing more
And my soul from that CO shadow
Shall be lifted – evermore!
