F:\Usi\6th Semester\Edu 373\Science Indicator Project

  1. 1. The Missing Link<br />
  2. 2. Science Indicator 4.6.2<br />Show that something may not work as well, or at all, if a part of it is missing, broken, worn out, mismatched, or incorrectly connected. <br />
  3. 3. Definitions<br />Missing- not found<br />Broken- not working properly<br />Worn out- cannot be repair<br />Mismatched- two parts that don’t fit together<br />Incorrectly Connected- put together the wrong way<br />
  4. 4. Definitions<br />Draw or write what you think each word means<br />Missing-<br />Broken-<br />Worn out-<br />Mismatched-<br />Incorrectly Connected-<br />
  5. 5. Background Information<br />Flashlight History<br /><ul><li>Definition: a small portable battery-powered electric lamp, typically flashlight consists of a small electric light bulb with associated parabolic reflector, powered by electric batteries, and with an electric power switch
  6. 6. Although a flashlight is a relatively simple device, its invention did not occur until the late 19th century because it depended upon the earlier invention of the electric battery and electric light.
  7. 7. The first flashlight was invented in 1898 by Conrad Hubert.
  8. 8. In 1896, the first dry cell battery was invented. Unlike previous batteries, it used a paste electrolyte instead of a liquid. This was the first battery suitable for portable electrical devices, as it did not spill or break easily and worked in any orientation.
  9. 9. On January 10 1899, American Electrical Novelty and Manufacturing Company obtained U.S. Patent No. 617,592 from David Misell, its English inventor. </li></li></ul><li>Background Information<br />Flashlight History<br /><ul><li>This "electric device" designed by Misell was powered by "D" batteries laid front to back in a paper tube with the light bulb and a rough brass reflector at the end.
  10. 10. The company donated some of these devices to the New York City police, who responded favorably to them.
  11. 11. These early flashlights ran on zinc-carbon batteries, which could not provide a steady electric current and required periodic 'rest' to continue functioning.
  12. 12. Because these early flashlights also used energy-inefficient carbon-filament bulbs, "resting" occurred at short intervals. Consequently, they could be used only in brief flashes, hence the popular name flashlight.</li></li></ul><li>Do you see the light?<br />Take the flashlight and put 2 AA batteries in the flashlight. Turn the flashlight on.<br />Write in your science journal what happened.<br />
  13. 13. Do you see the light?<br />Take the flashlight and put one AA battery and one D battery in the flashlight. Turn the flashlight on.<br />Write in your science journal what happened.<br />
  14. 14. Do you see the light?<br />Take the flashlight and put 2 D batteries in the flashlight. Turn the flashlight on.<br />Write in your science journal what happened.<br />
  15. 15. Perfect Match<br />Take the deck of cards and remove the 2 of hearts, 7 of hearts, 9 of hearts, King of hearts and Ace of hearts. With a partner play Old Maid, with the Joker as the old maid.<br />Write in your science journal what happened at the end of the game.<br />
  16. 16. Perfect Match<br />Put the 2 of hearts, 7 of hearts, 9 of hearts, King of hearts and Ace of hearts you removed back in the deck and play Old Maid again, with the Joker as the old maid.<br />Write in your science journal what happened at the end of the game.<br />
  17. 17. To Write or Not to Write<br />Take the pencil and put the lead in the pencil from the container labeled A. Write the following sentence- I went to the store.<br />Write in your science journal what happened. <br />
  18. 18. To Write or Not to Write<br />Take the pencil and put the lead in the pencil from the container labeled B. Write the following sentence- I went to the store.<br />Write in your science journal what happened. <br />
  19. 19. Questions<br />Why did some things (flashlight, game, and pencil) work, but others didn’t?<br />Can you think something else that wouldn’t work right if a piece was missing, broken, worn out, incorrectly connected, or mismatched?<br />
