  1. The universe is made up of stars, planets and other matter scattered throughout space. The earth The Solar System The Milky Way The universe

  2. A galaxy is a huge collection of stars held together by gravity. There are probably over a billion galaxies in the universe. The sun is just one of the common sized stars contained within our home galaxy, the Milky Way. • The solar system is made up of the sun and the objects that orbit(绕...轨道而行)it. These include the nine plants----Mercury水星, Venus金星, Mars火星, Jupiter木星, Saturn土星, Uranus.天王星, Neptune海王星and Pluto冥王星.

  3. the Milky Way

  4. The Solar System

  5. The Solar system

  6. Where are we?

  7. Unit 4 Astronomy: the science of the stars

  8. Warming up 1.When we talk about science ,what subject will come into your mind ? Physics chemistry biology geology mathematics

  9. 2.Some studies combine two or more these subjects. Discuss which science subjects are part of medicine, biochemistry , geophysics or astronomy. Astronomy Geophysics Biochemistry Medicine mathematics and physics geology and physics biology and chemistry biology and chemistry Frontier Science

  10. 3.Fill in the blanks with the four frontier science above. Medicine The scientific study of treatment of diseases and injuries. The study of the chemistry of living things. The scientific study of the earth’s atmosphere , oceans and climate . The scientific study of objects in space ,such as planets ,stars , comets and“black holes” Biochemistry Geophysics Astronomy

  11. Warming up: • Discussion: • What do we mean when we say we are studying a subject scientifically? To study a subject scientifically, you must: --- try to be objective; --- present your idea to be tested --- design an experiment to test the idea --- analyze the results --- draw a conclusion

  12. Warming up: Discussion: 2. What are the most important skills we need to be real scientists? Some of the important skills are: --- accuracy( or being very careful), --- a logical approach, --- thorough writing of the experiment so someone else could redo the experiment from your notes --- be able to draw conclusions from the evidence and not impose conclusions on the data.

  13. How life began on the earth The beginning of the universe Pangu separates the sky from the earth The sky and the earth were at first one blurred entity like an an egg. Pangu was born into it. The separation of the sky and earth took 18,000 years. Between the sky and the earth was Pangu, who went through nine changes every day, his wisdom, greater than that of the sky rose ten feet higher, the earth became ten feet thicker, and Pangu grew ten feet taller. Another 18,000 years passed, and there was extremely high sky, an extremely thick earth, and an extremely tall Pangu.

  14. Stories about the beginning of the universe in China:

  15. The Biblical Account “In the beginning God created the heavens and the earth.

Day 3: God spoke and created dry land Day 4: God spoke and created the sun, moon and stars Day 5: God spoke and created living creatures in the air and sea Day 6: God spoke and created the land animals and man Day 7: God rested and blessed this day calling it Holy

  16. Do you know what a scientific idea is? The Big Bang The big bang theory suggests that the universe was once extremely compact(紧密的) dense(密集的), and hot. Some original event, a cosmic (宇宙的) explosion called the big bang, occurred about 13.7 billion years ago, and the universe has been expanding (扩大的)and cooling.
