00:00:00,240 --> 00:00:05,740
Good morning, my name is Alexander Fleming and today I'm going to tell you about my story.

2
00:00:06,240 --> 00:00:10,560
I was born on August 6th in 1891 in Darwin, United Kingdom.

3
00:00:11,019 --> 00:00:18,280
I'm a Scottish physician and microbiologist and I discovered the world's first broadly effective antibiotic substance.

4
00:00:18,760 --> 00:00:25,940
I grew a mole named Penicillium and I found that it produced a substance that killed virus disease-causing bacteria.

5
00:00:25,940 --> 00:00:32,939
After some months of calling that substance mold juice, on 1929, I decided to name penicillin.

6
00:00:32,939 --> 00:00:38,939
In that year, in 1929, happened the Wall Street crash and the beginning of the Great Depression.

7
00:00:38,939 --> 00:00:45,939
The Great Depression was an economic crisis that lasted through the 1930s, before World War II.

8
00:00:45,939 --> 00:00:48,939
Now I'm going to explain you the Great Depression.

9
00:00:48,939 --> 00:00:51,939
During the 1920s, many people invested their money in stocks.

10
00:00:51,939 --> 00:00:59,060
stocks. For a few years, these stocks rose rapidly. However, in 1929, stock prices began to fall.

11
00:00:59,679 --> 00:01:05,939
In October, they crashed and many people lost all the money they had. Many banks failed because

12
00:01:05,939 --> 00:01:14,219
crowds of people tried to take out all their money at once. Factories and businesses closed

13
00:01:14,219 --> 00:01:18,019
because people were not able to buy the goods they sold.

14
00:01:18,739 --> 00:01:24,060
By 1932, about 12 to 13 million people were out of work.

15
00:01:24,379 --> 00:01:28,459
The situation in the United States affected countries all over the world.

16
00:01:29,359 --> 00:01:32,439
Hi, I'm Dira and today I'm going to talk about the Great Depression.

17
00:01:32,920 --> 00:01:38,079
The Great Depression was the longest and most serious downturn ever experienced by the world economy.

18
00:01:38,560 --> 00:01:40,219
Why was the Great Depression so important?

19
00:01:40,219 --> 00:01:48,219
It caused enormous hardship for millions of people and the failure of a large fraction of national banks, businesses and farms.

20
00:01:48,219 --> 00:01:51,219
What is the Wall Street crash?

21
00:01:51,219 --> 00:01:58,219
The Wall Street crash was a major American stock market crash that occurred in 1929 to 1939.

22
00:01:58,219 --> 00:02:05,219
How did the Great Depression end?

23
00:02:05,219 --> 00:02:12,219
The Great Depression, in simple words.

24
00:02:12,219 --> 00:02:17,219
The Great Depression was the worst economic downturn in history.

25
00:02:17,219 --> 00:02:30,219
in the history, from 1929 to 1939.

26
00:02:30,219 --> 00:02:37,219
How did they create the pressure?

27
00:02:37,219 --> 00:02:43,219
When war began, factories consumed the produce.

28
00:02:43,219 --> 00:02:55,879
tanks, airplanes, ships, guns and ammunition. Young men went to the army and people went

29
00:02:55,879 --> 00:03:05,979
back to working factories. Other people give credit to new programs from the 1930s for

30
00:03:05,979 --> 00:03:12,860
ending the depression who is alexander fleming and why he is important alexander fleming was a

31
00:03:12,860 --> 00:03:17,819
scientist and he discovered the penicillin the penicillin was the first antibiotic

32
00:03:18,460 --> 00:03:28,379
and it reduced the number of them and this is my present presentation bye
