Script
( I checked my
part that I said, especially part 4 )
Intro
Hui Gwan : We will go to electricity museum from
now on.
One,
two, three go!!
Jae hyeok : Where are we?
Hui Gwan : I did a mistake and teleport us
another place.
Min Hyuk : Oh! Look over
there.
Na Young : Let’s go
At museum
Jae hyeok : We arrived at here.
Here is electric museum. From now on we are going to look around this museum.
Each person is going to explain this museum each part
Part 1. History of
electric energy
Won Hyeok : The name of this corner is history of electric energy.
This corner shows chronology of the birth and development of electric energy.
It is watt's steam engine it is famous for its driving force of the Industrial
Revolution. It is the first power generation facility in Korea. As shown this
is a scale model. It is the first public transport - electric train. In 1899
the 동대문 power plant
supplied electric energy for electric train
Part2. Extension of electricity
Na
Young : In 1930s, there were large bodies of
water in North. Korea. So, there were 21 hydroelectric power generations around
river. Above all, ‘soopoong’ hydroelectric power generation that length is 900m
along the Amnokgang(Amnok river) is famous for large scale generation of
electricity. The scale is that long time ago, it could transmit electric power
to South Korea. It is very amazing thing!
Now, I will introduce how power can be
transmitted to our home. First, voltage is increased at hydroelectric power
generation and sent to substation. And then voltage is also sent to pole
transformer from substation. Let’s look at it! This is pole transformer in
1930s. Finally, voltage is decreased and sent to our home. So we can use
electricity. Thank you!
Part3.
Electricity in our life
Min
Hyuk : Electricity, one of the most important things in our lives has
been changed our life a lot. Telecommunication and radio broadcasting using the
electricity have been an remarkable progress. Telecommunication has
commercialized at 1890s by physicist, inventing a telegraphic instrument and a
telephone using electricity. It was not until 1920s by the invention of ‘A
vacuum tube radio’ the road of radio broadcasting has opened widely.
In this section you can see many kinds of electricity devices.
And here you will see familiar things such as movie projector, Korean typing
machine and electricity calculator.
Gramophone which Korean name is Chuck-Um-Ki, remembers the
person’s voice and repeat it exactly the same. Edison the inventor of thins
machine has installed his own company but unfortunately it couldn’t have been
progressed because of the other inventions. You can see that other inventions
in this area. Here are hair curling iron, waffle maker, toaster and there are
many kinds of tea pots.
Electricity has come deeply into our life and allow us to have
convenient life.
Part4. The development process of lighting
Hui
Gwan : Hi, This place is about the
electric light brightening over the Korea. We can see the development progress
of lighting in this place. From instruments before people used the electricity
to modern light like the bulb. There are so many things people used to
lightening the dark.
Let's
check what they are. First, This is flint. Ancient people used this flint to
lightening the dark. If you smash these
stones each other, it makes a spark and the spark makes a fire. Ancient people
used a fire as a light.
After
then people used candle and lamp. For example, this is Ho-Long in Korean,
people used this Ho-Long when they worked or studied in the room, at night. and
this is Nam-Po-Deung. and it was usually used in 1960s and people used
Nam-Po-Deung for moving in the dark.
These
are initial bulbs. As you know, Edison invented the bulb. First time, he used
carbon to make filament. But now, we use tungsten or nickel to make filament.
Because its durability is better than carbon. And this is the initial
flashlight. As you look at it, It is too big. The Flashlight have become
smaller and smaller. Now we use more portable flash light.
In our
daily life, there are so many bulbs for so many purpose. For example, this is
for car, this is for Christmas tree, this is for electric test, this is for
train. Until now, we checked the development progress of light. We can lighten
the dark easily now. But I wish we should not forget the day we were hard to
lighten the dark. And we can recognize the minor thing's importance. Thank you.
Part5. Electricmagnetic and Electric power
plant
Jae hyeok : Hi guys. Here is
electromagnetic part.
Take look at here. We can see many stuffs and many buttons
here. We can know what kind of magnetic waves are made by them. Let me try
this, I will push this button and let’s check it. We can check how much waves
are made by here. Microwave is 20 and mixer is 30 and here is another 3stuffs
hairdryer is 70, the biggest one and here is last three. Push it again. Yes 20,
30 and 10.
Come this way.
This part is about power plant. Unfortunately here is no
nuclear generation power plant. But here is thermoelectric power plan,
hydroelectric power plant and water pumping power plant. I think most of you
guys already know what is hydroelectric and what is thermoelectric so I will
explain briefly what is water pumping power plant.
Look at here, you can see blue circles. At first it follows
this way but next it changes flow direction. At night people don’t’ use much
electricity so there must be surplus electricity and we can use them when we
pull up the water higher and then next day we can use the water when we make
electricity that’s how water pumping power plant is working.
And here is another funny thing. This is quiz machine. Touch
the screen first and then touch a circle. It looks like each circle is a quiz.
You can check what you know here.
Thank you guys. I will finish now.
I really think this place is pretty good. If you have the time
to visit here, come here. Here is interesting than what I expected. Bye~
After watching
Hui
Gwan : Now, we will finish our project and we will go to home and have dinner.
Everybody : Bye~
