Tha Zin Television

Televisions show sounds and pictures. They get data from cables, discs, or over-the-air signals. They turn this data into sounds and images. People watch news and shows on them. You probably call them TVs.

John Baird made the first TV in 1925. It had one color. It could only show 30 lines. This was just enough room for a face. It didn't work well, but it was a start.

The first TV station was set up in 1928. It was in New York. Few people had TVs. The broadcasts were not meant to be watched. They showed a Felix the Cat doll for two hours a day. The doll spun around on a record player. They were experimenting. It took many years to get it right.

By the end of the 1930s, TVs were working well. America got its first taste at the 1939 World's Fair. This was one of the biggest events ever. There were 200 small, black and white TVs set up around the fair. The U.S. President gave a speech over the TVs. The TVs were only five inches big but the people loved it.

They wanted TVs. But World War II was going on during this time. Factories were busy making guns and bombs. When the war was over, TV spread across the country. By 1948 there were 4 big TV networks in America. They aired their shows from 8 to 11 each night. Local shows were aired at other times. Most of the time, nothing was shown at all.

TV was not "always on" like it is now. Color TVs came out in 1953. They cost too much money for most. Also, shows were aired in black and white. By 1965, color TVs were cheaper. TV stations started airing shows in color. People had to switch if they wanted to see the shows.

Now most TVs are high-def. This means that they have many lines on them. This makes the image clear. TVs have come a long way since Baird's 30 line set. High-def TVs have 1080 lines. There are state of the art sets called 4K TVs. These TVs have 3,840 lines. Some people watch TV in 3D. I wonder what they will come up with next. Smell-o-vision anyone?

Tha Zin Making Pan Pipes

On wednesday we got to make pan pipes out of straws. This theme for this term is Musical Madness so we got to make our own musical instruments. We needed to use 8 straws because there are 8 types of musical notes.

First we watched the video where Mrs Buchanan showed us how to make  a pan pipe. Then after we watched it we got to pick out 8 straws. We needed 8 straws, clear tape and scissors.

Later we cut the straws from the tip then taped it on the card board then tried it out. It worked really well but it made shushing noise. I loved it, it was so cool to play with and fun to use.

The instrument that I made was kind of a success and kinda not.It was really fun to play with and I enjoyed it.The only thing I wished was that it could make different sounds but not just the shushing noise.

I learn the 8 musical notes and it was quite fascinating and I liked playing the instrument.

I liked the instrument and I hope we get to make more instruments.

City Autumn
The air breathes frost. A thin wind beats
Old dust and papers down gray streets
And blows brown leaves with curled‐up edges

And an old man totters past with a cane
Wondering if he’ll see spring again.
