Tsiolkovsky carried out experiments on steam engines for a time, but then he
returned to the theoretical study of the metallic dirigible. In 1887, his first published
paper on the dirigible appeared. Mendeleyev was interested in this work and helped
Tsiolkovsky. The account of this aeronautical work was submitted to the Academy of
Sciences who regarded it favourably and made Tsiolkovsky a grant of 470 roubles.
He had not given up his idea about space travel. A popular report on this
subject was first published in 1895. Tsiolkovsky's idea of a spaceship was based on
the use of liquid fuels.
During the next fifteen years Tsiolkovsky worked over other designs for
spaceships. They were not meant to be working drawings for the construction of these
vessels but as a rough guide to the equipment. Some of them are now standard
practice in the guided missile field. He published several articles and books dealing
with the mathematical theory of rocket flights and space travel. His calculations were
used in modern theory of cosmonautics and practical space flights. They showed that
it would be possible to travel out into space in rockets and even to set up manned
space stations around the Earth.
Tsiolkovsky's contribution to science is so great that he is considered to be
“Father of Cosmonautics”.

1) The name of the scientist you’d like the street to be named after.
2) Where and when he/she was born and worked.
3) The field of science this scientist worked in.
4) The discovery or invention he/she made.
5) Where the results of his/her work are used now.
6) Why you have chosen this very scientist.
III. Discuss the traits of character of a real scientist.
IV. Speak about any great scientific discovery.
V. Pretend you are an inventor. Here is your chance to make you own invention.
Describe you invention. What does it look like? What does it do? How does it
work? Add drawings or a diagram if you wish. Your invention can be funny or
serious.
VI. Write a short sci-fi story. The main hero wants to change the weather and the
