Ход урока.
-
Good morning,
ladies and gentlemen. Today we are going to speak about great Russian
scientist D. I . Mendeleev.
-
What do you
know about this personality? (A great Russian scientist, a world-known chemist,
a public leader, a correspondent member of the Academy of Sciences).
-
To warm up do
exercise 1.
Exercise

Write
down as many words as you can
GREAT
SCIENTIST
-
To get more
information about his life I’d like you to read the following text.
Text
Read the text, put the abstracts
into the necessary order. Think of the title.
Mendeleev’s
parents were Maria Mendeleeva and Ivan Mendeleev. He was the seventeenth child
in his family. His father worked as a teacher. Maria Mendeleeva worked in the
glass factory which belonged to her family. When Mendeleev was 13 he entered
the Gymnasium in Tobolsk.
From
1859 to 1861 Mendeleev worked in Heidelberg. In April 1862 he married
FeozvaNikitichnaLeshcheva. Two years later Mendeleev became a professor at the
Saint Petersburg Technological Institute. In 1865 he became a professor at Saint Petersburg State University. The same year Mendeleev completed his dissertation
"On the Combinations of Water with Alcohol".
Dmitri
Ivanovich Mendeleev was born on 8 February 1834 near Tobolsk. He was a great
Russian scientist, talented chemist. He is best known for his development of
the periodic law of the properties of the chemical elements.
In
1849 his family moved to Saint Petersburg. In 1850 Mendeleev joined the Main
Pedagogical Institute. Later Mendeleev became a science master of the Simferopol.
After
this, Mendeleyev tried to classify the elements according to their chemical
properties. In 1869 he published his first version of what became known as the
periodic table, in which he demonstrated the periodic law. In two years he
published the second version, in which he left the gaps for elements that were
not yet known. By 1871 Saint Petersburg was known as a center for chemistry
research.
Mendeleev got a lot
of awards from different scientific organizations but he resigned from Saint Petersburg University in 1890. Three years later Mendeleev became Director of the
Bureau of Weights and Measures. His task was to formulate new standards of
measures. Mendeleev worked out new principles of metrology.
At
the age of 73 Dmitri Mendeleev died of influenza in Saint Petersburg.
Words:
Property – свойство
To belong
– принадлежать
Master of
Science – Магистр наук
Gap – пропуск
Award - награда

-After reading match
the date and the event.
Exercise 3.
Look
through the text again and match the date and the fact
1907
A famous periodic table appeared
1859
Mendeleev was born
1869
A great scientist died
1893
He finished his work on water and alcohol
1834
Mendeleev lived and worked in Germany
1865
Mendeleev started to develop the principles of metrology
-
As you
understood from the text the most important discovery made by D. I. Mendeleev
was the Periodic Table. When did the periodic table appear? (1869)
-
Read exercise 2
and choose true or false.
Exercise 4.
Write
True (T )or False(F)
1. Each
element has 2 cells in the table.
2. There
are 7 periods in the Periodic table.
3. The
Periodic table has 8 groups.
4. All the
elements are classified as metals and non metals.
5. There
are 108 chemical elements in the table.
- I hope,
you liked the lesson and got more information about such a famous scientist. If
you have questions, you may ask me.
Homework:
To prepare a report about any famous scientist.
