открытые уроки по английскому языку в колледжах

Цель занятия: развивать у студентов речевые умения: поисковое чтение текстов на английском языке, умение слушать и понимать информацию на английском языке по заданной теме, умение письменно излагать прослушанный материал, умение высказывать свое мнение; пополнить лексический запас и расширить кругозор студентов в области науки и инженерии.

I. Warming up: Студенты работают самостоятельно, потом в парах проверяют друг друга, затем учитель выборочно проводит контроль чтения.

2. Read about the inventions and find the information to fill in the table below: студенты работают самостоятельно, проверка проводится фронтально.

Telephone

Invented by: Alexander Graham Bell

Nationality: Scottish

Date 1876

Purpose: to transmit the sound of the voice by wire, over long distances

Alexander Graham Bell was a doctor. He worked with deaf children and understood the way sounds caused vibrations. While only in his 20's, he discovered a way of converting vibrations into variations in electric current - and back again.

His telephone had a diaphragm (a thin metal sheet), which vibrated when spoken to: close behind the diaphragm was an electromagnet, which convened the vibrations into electric signals.

Bells telephone had a single transmitter/ receiver: when you had finished speaking into the microphone you held it to your ear and listened to the other person's voice.

In 1877 Thomas Edison invented a better, separate, microphone using carbon granules behind the diaphragm. Apart from that, today's telephone is as Bell invented it. Would you believe it?

There are nearly a billion telephones in use around the world. The demand seems never ending.

 Safety Pin

Invented by: no information

Nationality: Mediterranean

Date: about 2000 ВС

Purpose: to protect the user from the unguarded point of the straight pin - which had been invented several hundred years earlier.

The Sumerians invented straight pins more than five thousand years ago. The first safety pins were used a thousand years later in Greece, Egypt, Italy and Sicily.

Early safety pins were merely straight pins bent double with the ends fitting into a slot or hook. Something was needed to stop the point from slipping free. Someone thought of making it spring tight. To do this, the pin was given a circular twist at the bend. The same principle is still used today.

Урок английского языка Inventions

Aqualung

Invented by: Jacques Cousteau and Emil Gagnon

Nationality: French

Purpose: to supply air to free - swimming underwater swimmer,     

at the same pressure as the surrounding sea.   

Jacques Cousteau told Gagnon exactly what he wanted. Emil Gagnon made it. With unregulated compressed air supplies, and with sea pressure increasing with depth, there was always a danger of an underwater swimmer's lung collapsing.  

The aqualung has a special valve regulating the air supply. As the diver breathes out the pressure of his breath opens an outlet valve, which also shuts off the air supply as he breathes in, the internal pressure falls and the outside water pressure closes the outlet valve and switches the compressed air supply back on. The air flows in until the pressure in the valve is the same as the pressure of the outside water. Then it cuts off.

Tape Recorder (and Walkman)

Invented by: Valdemar Paulsen

Nationality: Danish 

Date: 1898   

Purpose: initially, a telephone message - taking device: nowadays, largely music recording

Paulsen’s first magnetic recording device used wire and then later steel tape. It was designed to record telephone messages.          

In 1935 the first plastic recording tape was introduced: it was coated with iron oxide (tape today is often coated with chromium oxide). Early tape recorders were bulky machines with the tape running from one large reel to another.

In the 1960s Philips introduced the compact tape - cassette. This was a complete, easy to handle, plastic package of twin spools and narrow recording tape.

The cassette led to Sony's invention, in 1979, of the Walkman. It was a complete, portable, stereo cassette player, little larger than a cassette box. There was no room for a loudspeaker, so earphones were provided, with tiny super - efficient plastic membranes.
