Подведение итогов занятия
OK, what were we talking about today?
We were talking about Science and scientists.
What is the difference between science and technology?
Science attempts to explain how and why things happen and technology makes things happen.
Has science great influence on our lives?
Yes it has. The discoveries of science help shape our views about ourselves and provide the basis of modern technology – the tools and machines that make our life and work easier.
What scientists were we speaking about?
We were speaking about M. V. Lomonosov and D. I. Mendeleyev.
Did you learn something new about them?
Yes, I did. I learned that Lomonosov rejected the phlogiston theory of matter, anticipated the kinetic theory of gases, stated the idea of conservation of matter, recorded the freezing of mercury and observed the atmosphere of Venus.
I learned something new about Mendeleyev. I learned that he had investigated theory of solution and had found that the best proportion of alcohol and water in vodka is 40.
Do you agree that these scientists did much for Russian science?
Yes of course. It is true.
