1. Natural Science What is science?

2. The word "science" probably brings to mind many different pictures: a fat textbook, white lab coats and microscopes, an astronomer peering through a telescope, a naturalist in the rainforest, Einstein's equations scribbled on a chalkboard, the launch of the space shuttle, bubbling beakers ….

3. All of those images reflect some aspect of science, but none of them provides a full picture because science has so many facets.

4. These images all show an aspect of science, but a complete view of science is more than any particular instance.

5. Science is both a body of knowledge and a process. In school, science may sometimes seem like a collection of isolated and static facts listed in a textbook. Just as importantly, science is also a process of discovery that allows us to link isolated facts into coherent and comprehensive understandings of the natural world.

6. Science is exciting. Science is a way of discovering what's in the universe and how those things work today, how they worked in the past, and how they are likely to work in the future. Scientists are motivated by the thrill of seeing or figuring out something that no one has before.

7. Science is useful. The knowledge generated by science is powerful and reliable. It can be used to develop new technologies, treat diseases, and deal with many other sorts of problems.

8. Science is ongoing. Science is continually refining and expanding our knowledge of the universe, and as it does, it leads to new questions for future investigation. Science will never be "finished."

9. Science is a global human endeavor. People all over the world participate in the process of science.

10. Discovery: The spark for science

11. "Eureka!" or "aha!" moments may not happen frequently, but they are often experiences that drive science and scientists.

12. For a scientist, every day holds the possibility of discovery — of coming up with a brand new idea or of observing something that no one has ever seen before.

13. Vast bodies of knowledge have yet to be built and many of the most basic questions about the universe have yet to be answered:

14. What causes gravity? How do tectonic plates move around on Earth's surface? How do our brains store memories? How do water molecules interact with each other?

15. We don’t know the complete answers to these and an overwhelming number of other questions, but the prospect of answering them leads science forward.

16. EVERYDAY SCIENCE QUESTIONS

17. You've probably posed many perfectly valid scientific questions yourself: how can I get an A, why do my feet smell, why does my friend get drunk so easily?

18. Discoveries, new questions, and new ideas are what keep scientists going, but they are only one part of the picture; the rest involves a lot of work.

19. In science, discoveries and ideas must be verified by multiple lines of evidence and then integrated into the rest of science, a process which can take many years.

20. Line of Evidence Evidence drawn from one sort of test result that bears on the accuracy of an idea. In science, it is often desirable to use multiple lines of evidence (drawn from different sorts of tests and even different fields of study) to evaluate a scientific idea.

21. The process of scientific discovery is not limited to professional scientists working in labs. The everyday experience of deducing that your car won't start because of a bad fuel pump, or of figuring out the best clothes to wear on a hot day shares fundamental similarities with classically scientific discoveries.

22. deduce To figure out through logical reasoning. Deductions are often based on established knowledge and/or assumptions.

23. These activities all involve making observations and analyzing evidence — and they all provide the satisfaction of finding an answer that makes sense of all the facts.

24. evidence Test results and/or observations that may either help support or help refute a scientific idea. In general, raw data are considered evidence only once they have been interpreted in a way that reflects on the accuracy of a scientific idea.

25. fact Statement that is known to be true through direct observation. Since scientific ideas are inherently tentative, the term fact is more meaningful in everyday language than in the language of science.

26. Some psychologists argue that the way individual humans learn (especially as children) bears a lot of similarity to the progress of science: both involve making observations, considering evidence, testing ideas, and holding on to those that work.

27. test In science, an observation or experiment that could provide evidence regarding the accuracy of a scientific idea. Testing involves figuring out what one would expect to observe if an idea were correct and comparing that expectation to what one actually observes.

76. Review Questions. What do you think of when you think of “Science”? Give some adjectives and nouns which can complete this sentence: “Science is ……….”

77. What sort of experiences often drive scientists? Would you say that they are driven more by emotion or by rationality?

78. What are some basic questions that are yet to be answered by science? What are some everyday enquiries that you have, that are similar to scientific questions?

79. In science, it is not enough to have ideas. What must happen to those ideas before they are accepted in science?

80. In your own words, explain what the following terms mean. Line of evidence. Deduce. Evidence. Fact. Test.

81. What are observations? How is the way people learn similar to the process of science?
