  2. Warming up Talk about science and scientists

  3. Nothing in life is to be feared. It is only to be understood ---Marie Curie She discovered radium and polonium

  4. Genius is one percent inspiration and ninety – nine percent perspiration. --Thomas Alva Edison He invented the light bulb .

  5. Imagination is more important than knowledge. ---AlbertEinstein He built the Theory of Relativity.

  6. It takes a very unusual mind to undertake analysis of the obvious. --Alfred North Whitehead His best known work in mathematics is Principia Mathematica.

  7. You cannot teach a man anything, you can only help him find it within himself. Galileo Galilei He proved that the theory of Copernicus that the sun is the centre of the universe is right.

  8. Theory of Evolution Charles Darwin

  13. Great mind No 2 : _______ 1.●rockets ●agriculture ●gravity ●radioactivity ●outer space 2. The scientist’s name is similar to the English word for _____. ●something not old ●something not short ●being interested in something

  14. Great mind No 3: ________ 1. What is this man known for ? ___________________________ 2. He wants to be called the _______. Why? modern rice farmer Long friendship with all the farmers in China

  15. Marie Curie Great mind No 1:________ Great mind No 2 : _______ Great mind No 3: ________ Newton Yuan Longping

  16. Speaking Debate which one is the most important. 1 Biology 2 Chemistry 3 Physics 4 Maths 5 Computer science

  17. Useful expressions That’s correct. It’s clear that… I doubt that… That’s true…. It’s hard to say… Well, maybe, but.. There is no doubt that… What’s your idea? Have you thought about…

  18. Biology We can learn how to fight disease, How to protect the environment, How to grow plants for food. Essential to protecting the ecological balance and environment; people can’t live without living things and medicine.

  19. Chemistry Is the key to the progress of human being; We can understand how the human body works and make medicines to cure disease. Chemistry also tell us what plants are made of and how we can make them grow faster and faster. Without it, we can’t know what caused pollution.

  20. Physics Widely used in many fields, such as medicine, industry and agriculture. Without physics, we wouldn’t understand know how to build cars And we wouldn’t understand things like electricity. Physics is by far the most practical branch of science.

  21. Maths You can’t learn physics or chemistry well without a good knowledge of maths. It is a tool in science and engineering.

  22. Computer science It is now an indispensable tool in many fields. It can settle all kinds of problems at a high speed and can help people work easily.
