Transcript of The Radio: Science Artifact Project

Alyssa Furukawa and
Olivia Pole The Radio Informs people with the latest news
Gives summaries of missed events.
Provides lots of music for people.
Helps people communicate. What does the radio do? Who invented the radio? -Lee DeForest, who worked on AM radio space telegraphs, created the Audion radio in 1906.

-Two other people that were a major part in the radio were Nikola Tesla, who worked on wireless radio transmission, and Guglielmo Marconi, who specialized in radio communication. How was the radio used when it was first invented? How is it used now? -When the radio was first made, it was used to send messages from one person to another, and also for navigation purposes. Now, it is used for that along with entertainment, music, and news and traffic updates. -The HD radio that broadcasts much clearer sound.
-RDS, which is Radio Data System. It was innovated to broadcast info and navigation. What are some innovations the radio has undergone since the creation of it? What area of technology best classifies the radio? -Provides a wide variety of music and entertainment.
-A fast way to hear about the news and traffic.
- A quick way to find out about sports scores.
-And so much more, the radio can even be placed in cars! Some Positive Impacts
of the radio: -The telegram became virtually unused.
-People want more and better innovations and become greedier about it.
-Broadcast radio encourages people to stay indoors and therefore become less social.
-Radio waves could become dangerous, because the energy can be absorbed into your body and create too many heat waves. Some Negative Impacts
of the radio: -Information and Communication Radio’s need to broadcast a signal to get all over the place. Scientists need to know how to get the best coverage of a broadcast signal whether it’s live or not. How science helped create the radio: The technology to make radio’s portable, able to be put in cars, and to be live or recorded takes lots of modern technology. How techology helped create the radio: An engineer had to create a radio with its antenna to reach far away signals to bring it wherever you were playing the radio. Now, radios are small enough to be able to be installed in cars to play music, hear sports scores, and get traffic updates and breaking news. Radios went from being large, heavy stands that play music to small, portable, car radios! How engineering
helped create
the radio: A mathematician had to figure out exactly how far a radio signal could reach and how many signal towers had to be placed in a city and where/how far away from each other they had to be placed. How math helped
create the radio: -Lee DeForest, president and secretary of DeForest Radio Telephone and Telegraph, and inventor of the Audion Radio. “I came, I saw, I invented—it’s that simple—it’s all in your imagination.” THE END The need for a radio includes: fast communication, quick updates on things like breaking news, traffic, missed events, and the need for portable music (this was before the MP3 was invented). Why are most products innovated? A flying car. We would innovate a flying car so it would help traffic, you could get to places faster, and you could be either on the ground or in the air. The flying car would have a radio in it that needs signals to broadcast up in the air. One product we'd like to innovate is..
