Topic:
- Listen
to the Radio
|
- Easier - Radio is
a way of sending sounds through the air by
electrical waves. Radio also refers to the
equipment that is used to send and receive those
broadcast waves and convert them into sounds.
-
- Harder - Radio,
the shortened name for radiotelegraphy, is an
important means of communication. It enables people
to send words, music, codes, and other signals to
every part of the world and even into deep space.
Radio works by creating communication signals and
changing them into radio waves, a type of
electromagnetic wave. These radio waves are then
transmitted through the air and space at the speed
of light - - 186,282 miles per second. They can
even get through some solid objects, like building
walls. A radio receiver changes the waves back into
their original sounds.
-
- Broadcasting ranks as the most familiar and
widespread use of radio. Radio broadcasts feature
music, news, discussions, interviews, descriptions
of sports events, and advertising. In earlier times
before widespread use of television, radio also
delivered dramas, comedies, variety shows, live
music, and other kinds of programs. Today, many
people wake up to clock radios, drive to their work
listening to car radios, and also spend some of
their leisure time hearing their favorite radio
programs. In addition to broadcasting, radio is
also used for quick communication by pilots, police
officers, firefighters, and other individuals.
Scientists use radio waves to learn about the
weather. Some telephone messages are carried by
radio. Some radio enthusiasts operate their own
amateur radio stations. In other kinds of uses,
radio beams send communication signals for
navigation instruments and remote control devices
for all kinds of different equipment.

Radio Works by M. Brain from
HowStuffWorks
- http://www.howstuffworks.com/radio.htm
- 'Radio waves' transmit music, conversations,
pictures and data invisibly through the air, often
over millions of miles -- it happens every day in
thousands of different ways!

- For almost 100 years radio has allowed us to
send sounds over the air. How, exactly, is this
done? The activity in this section shows you
how.

- Hello Radio from the American Radio Relay League
- http://www.hello-radio.org/
- Getting started in Amateur Radio has never been
easier. First, locate a radio club in your area.
Begin learning about the entry-level exams for an
amateur (ham) radio license.

- After exploring several of the
websites on radio history and technology,
complete one or more of the following
activities.
-
- Build Your Own Radio. Find some
help at sites like (1) Build
Your Own Crystal Radio at the
American Museum of Radio, (2)
Crystal
Radio Page, (3) Oatbox
Crystal Set Project, (4) Project
Crystal Radio, (5) Crystal
Radio Construction Notes, and (6)
How
A Crystal Set Works. An alternative
radio plan can be seen at Foxhole
Radio. Build one from 'scratch' or you
can purchase a kit for a crystal set at an
electronics store like Radio
Shack.
-
- Complete A Radio WebQuest.
Follow or adapt the procedures that you
find at the following webQuest sites:
*Both
WebQuests Highly Recommended - Take Your
Pick!
- 1) Radio Days by C. Matzat (Grades
6-8) http://www.thematzats.com/radio/
- 2) Radio Discovery Web Quest by L.
Taylor (Grades 3-7)
- http://www.windarooss.qld.edu.au/Main_Pages/Radio_Webquest/welcome.htm
-
- Prepare To Be A Radio
Announcer. Do you know that public
speakers or people who want to work in
radio and television often practice saying
tongue twisters to help them speak
clearly. Try your hand at (1) Tongue
Twisters at CBC 4 Kids, (2)
Tongue
Twister Database, and (3) Tongue
Twisters at The Childrens Stomping
Ground. Next you could write some of
your own tongue twisters; get some startup
ideas at Tongue
Twisters.
-
- Write A Story About Radio.
Create a story that involves a radio. You
may want to set your tale in the 1920s and
imagine what life would be with a radio in
your house. Or place yourself in a wartime
survival situation and you have a windup
radio. Or even better, work on a story
idea of your own. Share your efforts by
publishing your finished radio story.
-
- Write And Perform A Radio
Script. Use the websites on
scriptwriting and broadcasting to learn
more about radio. Write a script and then
perform the program. Audio tape your radio
show so that you can listen, evaluate, and
improve your performance.
-
- Put Together A Radio Exhibit.
See if you can build a radio museum.
Gather as much information as you can
about their history. See how many
different types of radios you can collect:
homebuilt radios, crystal sets, battery
models, and transistor radios. Remember,
your museum could be 'virtual.' You would
not have to have the actual radio but
would need a photo or illustration.
-
- Join A Radio Club. See if your
school has a radio station and or club to
join. If not, gather a group of your
friends and classmates who are interested
in learning about radio broadcasting. Plan
and produce your own radio programs. If
you have enough numbers you can delegate
responsibilities for areas such as news,
sports, commercials, radio dramas,
advertising, and sound effects. Have fun
and practice, practice, practice.

Learning with an AM Radio by A. Ninno

- By operating an AM radio, students will
practice listening and note taking skills, learn
about local and regional US geography (cities,
states) as well as topics in other academic
subjects as appropriate for their specific grade
level. It is important to understand that the radio
is a general purpose tool for learning, like a
computer, and may be used by students to practice
information seeking and communication skills across
a variety of academic subjects.
