the evolution of Universe, Earth and Life

April 13, 2012

(Energy, Chemical reactions, Structure of matters will be taught in the

second semester)

The Goals of this course

1. To achieve scientific literacy by dealing with the

scientific aspects of problems that come into public

debate.

2. To improve English skills within the intellectualframework of scientific areas.

Students Naturally can get more familiar withthinking and expressing in English by reading andwriting in English with various fields of science

Enjoy Science!

Outline of todays lectureJoy of Science as a Scientific Literacy course

n 1. The importance of scientific literacy: Why we need toobtain scientific literacy

The Scientific Literacy


17/41

1. Importance of Scientific Literacy

n Scientific literacy helps consumers make informeddecisions.

n Todays workplace depends on science.n Scientific literacy provides a foundation for teaching

children.

n Scientific literacy allows you to share in the joy ofscience.

Why do we need scientific literacy?


18/41

2. Objectives of this course

n 1) By Organizing our presentation around the central GreatIdeas rather than around specific disciplines, students can deal

with the universe as it presents itself to them

n 2) By Integrating the concepts of each lesson to be discussedrelated to every area of science, students can obtain better

understanding of science and the universe as a seamless web

of interacting phenomena


19/41

The Organization of Science

n Science is organized around a hierarchy of fundamentalprinciples. For instance, overarching concepts about forces,

motion, matter, and energy apply to all scientific disciplines,

including physics, chemistry, biology, astronomy, and geology

n Additional great ideas relate to specific systems molecules,cells, planets, or stars.

n A seamless web of scientific knowledge draws a larger,integrated picture of our universe

n Technology has been developed while the results of scienceare applied to commercial or industrial goals.

3. Science: The Way of Knowing

Why Study Science? Science,

n gives us most powerful tool to understand how our world worksand how we interact with our physical surroundings.

n provides a framework for learning more and tackling newquestions and concerns that come our way.

n helps us to predict and cope with natural disasters, diseases,and to discover new materials and technologies.

n Provides an view of symmetry of the universe and its workingsform the unseen world of the atomic nucleus to the vastness of

space.

Definition of Science

4. The Scientific Method

n Observations:should be re-produciblen Experiments: based on careful measurementsn Hypothesis: a tentative educated guess by collected a number

offacts which are confirmed observations

n Predictions: led by hypotheses, can be tested by moreobservations and experiments

n Scientific Law: a regular, predictable pattern of behavior innature

n Scientific Theory: a well-substantiated explanation of the naturalworld based on independently verified observations and tests

n Mathematics: the language of science experimental analysesand developments of theories

The tool to distinguish Science

Physics

n The search for laws that describe the most fundamental aspectsof nature: matter, energy,

n All natural systems display these basic phenomenan The starting point for almost any study of how nature works


26/41

Chemistry

n The study of atoms in combination

n Chemicals form every material object of our worldn Chemical reactions initiate vital changes in our environment and

our bodies

n A practical science


27/41

Biology

n The study of living systems

n Scales of from microscopic molecules and cells to expansiveecosystems


28/41

Astronomy

n The study of stars, planets, and other objects in space

n Tremendous discoveries thank to the development of powerfulnew telescopes and robotic space exploration

(Pluto in the sequence of 9-plante of our solar system is

demoted to non-planet)


29/41

Geology

n The study of the origin, evolution, and present state of Earth.n The study of other planets by understanding our own world


30/41

Pseudoscience

n Pseudoscience claims to be scientific, but it cannot be analyzedusing the scientific method.

n No reproducible test Scientific ideas are testable and couldbe wrong

n Not science but belief or dogman Examples of Pseudoscience:

UFOs, crystal power, astrology

5. Science of Evolution

n Evolution: Biological evolution??The theory of evolution by Charles Darwin???

n Exploring chronologically the evolution of universe, solar systemand life on earth Can integrate fundamental concepts in physics, chemistry,

and biology, and then provide an interdisciplinary

understanding of evolution

n Can learn- How science works

- How it is used to unravel the mysterious of the universe

- How physics, chemistry, and biology have developed

expanding and cooling ever since

What to Understand from

the Concept of Evolution

n Evolution is the result of cumulative changes over time thatoccur in all realms of the natural world.

n Various processes underlie these changes in both the physicaluniverse and living systems.

n There are differing time scales and rates of change.n There are connections and relationships between the physical

universe and the life it hosts.

n Science is a process of advancing our understanding of thenatural world, not a set of final answers or beliefs.
