4. The Ravenby 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."

5. 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.

6. 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.”

7. Brief Biography of Poe Born in Boston in 1809 to Elizabeth Arnold Poe His father abandonded the family and his mother died before he reached the age of two Raised by a tobacco merchant named Allan Studied in England and the University of Virginia Joined the army and was discharged after two years Appointed to West Point then quit Published poetry and prose Gained fame in 1845 by publishing “The Raven” Prone to drinking problems Married twice

8. What we know about Poe’s Last Days • In 1849, had a drink at a birthday party then disappeared for three days. • He was found in Baltimore very sick and delirious • He died in hospital and was buried in Baltimore … But, how did he die?

9. Theories on Poe’s Death • Beating • Epilepsy • Dipsomania • Heart condition • Toxic disorder • Hypoglycemia • Diabetes • Alcohol dehydrogenase • Porphyria • Delerium tremens • Rabies and...

10. Or Possibly? He is not dead - he is alive and well in Memphis with his good friend Elvis

11. 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. http://www.mcsrr.org/graphics/poeposter.jpg

21. Chemistry of CO Detectors

22. 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

23. 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

25. 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

26. 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. http://www.chemistry.org/portal/a/c/s/1/feature_ent.html?id=04dd47d40b8211d7f0856ed9fe800100

34. Recommendations on CarbonMonoxide 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

36. 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)

37. 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 John Smith Ellen Rumball “Twas brillig and the Slythy toves Did gyre and gimball In the wabe All mimsy were the Borogroves All the momeraths Outgrabe - Lewis Carroll

38. “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.

39. A poem about Hemoglobin by Roald HoffmanNobel 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…

40. 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!

41. 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!
