CER Checkpoint: Best Communication Device

Last updated about 2 years ago

1 question

Scenario: Communications can be sent in many different ways. In Africa, New Guinea, and tropical America, people have used drum telegraphy to communicate with each other from far away for centuries. Native Americans used smoke signals from their fires. Others used a telegraph machine to produce short and long sounds, called Morse code. Morse code was used later on by submarines with flashing lights. A cell phone turns your voice into a special type of electricity and sends it over the air to a nearby cell tower. The tower sends your voice to the person you are calling within milliseconds. Information, including pictures, graphs, and charts, can also be transmitted with cell phones. 

Fire outposts are often used in the mountains of Colorado to watch for deadly forest fires. Fire outposts are equipped with emergency supplies including cell phones, flashlights, and a telegraph machine with a manual. Forest rangers working at the outpost notice flames about 100 miles east of the tower. When they try to call the ranger’s station, their call won’t go through. Further investigation shows that the cell tower has been damaged. If they don’t get word to the fire station soon, the town on the other side of the mountains could be destroyed. It will take too long to drive the winding road down to the station. The smoke in the sky is starting to get thick, and they have to think fast.

Prompt: Write a scientific reason explaining which type of communication from the background is best for the scenario above.
