Warming Up 1.Who have been developing the science and
technology?2.How many scientists do you know?ScientistsSome information about scientistsArchimedes, Ancient Greek (287-212 BC), a mathematician.Charles Darwin, Britain (1808-1882).The name of the book is Origin of Species.Thomas Savery (1650-1715) was an English military engineer and inventor. Thomas Newcomen (1663-1729) was an English blacksmith, who invented the atmospheric steam engine, an improvement over Thomas Savery's previous design.? James Watt (1736-1819) was a Scottish inventor and mechanical engineer, who was renowned for his improvements of the steam engine. Newcomen’s steam engineGregor Mendel, Czech, a botanist and geneticist.Marie Curie, Polish and French, a chemist and physicist. She discovered radium.Thomas Edison, American, an inventor. He invented the lights and the gramophone.Mona LisaLeonardo da Vinci, Italian, an artist.

They have an unknown cause and may do great harm to people.
People could be exposed to infectious diseases, so may animals, such as bird flu. AIDS, SARS are infectious diseases. They are difficult to cure.
What do you know about infectious diseases?
What do you know about cholera?
Do you know how to prove a new idea in scientific research?
It’s the illness caused by a bacterium called Vibria cholerae.Draw a conclusion /Think of a method/ Collect results
Make up a question / Find a problem / Analyse the results/ Repeat if necessary1.Which scientist discovered that objects in water are lifted up by a force that helps them float? Archimedes
2.Who wrote a book explaining how animals and plants developed as the environment changed? Charles Darwin
3.Who invented the first steam engine?
Thomas Newcomen
4.Who used peas to show how physical characteristics? Gregor Mendel
--tics are passed from parents to their children?
5.Who discovered radium? Marie Curie
A surveyQuiz
Questions6.Who invented the way of giving electricity to every
--body in large cities?
7.Who was the painter that studied dead bodies to
improve his painting of people?
8.Who invented a lamp to keep miners safe under
-ground?
9.Who invented the earliest instrument to tell people
where earthquakes happened?
10.Who put forward a theory
about black holes?(Thomas Edison)(Leonardo da Vinci)(Sir Humphry Davy)(Zhang Heng)(Stephen Hawking)Reading1.There’re 7 stages in the reading,too.What order?Find a problem Make up a questionThink of a methodCollect resultsAnalyse resultsRepeat if necessaryMake a conclusion2.Fill in the chart.Nobody knew the cause of choleraStrange cloud that attacked victimsPerple absorbed the disease with their mealsCollect data from the next cholera attack to test theories.Try to prove which method was correct.He found the cause of cholera was the polluted water.Idea 2.Because the data showed a connec
-tion with the water.John Snow was able to defeat cholera once
its cause was known.3.What disease do you think is similar to cholera to
-day?(SARS, AIDS and so on)4.John Snow believed Idea 1 was right. How did he
finally prove it? He found an outbreak that was clearly related to cho
-lera, collected information and was able to tie cases
outside the area to the polluted water.5.Do you think John Snow would have solved this
Problem without the map?Why?No.The maps helped John Snow organise his ideas. Some detailed information
