Dacota_blue: Branches of science

1. Branches of Science LESSON 1.2

2. INTRODUCTION Before science became the science that we know today, natural phenomena were explain based only on personal observations and understanding. During the time of the Greek mathematician, Pythagoras, arithmetic, geometry, music, and astronomy were recognized as science.

3. In the 19 th Century, scientists finally realized that pure mathematics was not science because it was a series of logical relations that did not depend on the laws of nature. But because mathematics is often used in the study of science, it is now considered as an allied field. Mathematics is referred to as the language of science since it is used to communicate the results obtained in scientific work. SCIENCE and mathematics

6. LIFE SCIENCE LIFE SCIENCE , also known as BIOLOGY , studies all aspects of living things. It studies the behavior, history, and development of living organisms. JEAN –BAPTISTE LAMARCK (French): introduced the term “biology” in the 1800s. Some of the subdivisions of the life science are these following: BOTANY : the study of plants ZOOLOGY : the study of animals GENETICS: the study of the function and behavior of genes

7. LIFE SCIENCE LIFE SCIENCE , also known as BIOLOGY , studies all aspects of living things. It studies the behavior, history, and development of living organisms. THOMAS HENRY HUXLEY (British Biologist) 1825 -1895: insisted that all living things be studied in an integrated way. Today, scientists appreciate Huxley’s way of thinking because many lower organisms are now categorized as neither plant nor animal.

8. LIFE SCIENCE The LIFE SCIENCES may be subdivided according to units of study: molecule, cell, organisms, or even population. The following divisions of life sciences developed through the years: BIOMEDICINE : is the application of biological knowledge to human health.

9. LIFE SCIENCE The LIFE SCIENCES may be subdivided according to units of study: molecule, cell, organisms, or even population. The following divisions of life sciences developed through the years: CELLULAR BIOLOGY (Cytology): sometimes referred to as cell biology, aims to understand the properties, structure, activities, and functions of the cell, from the simplest to the most complex organism.

10. LIFE SCIENCE The LIFE SCIENCES may be subdivided according to units of study: molecule, cell, organisms, or even population. The following divisions of life sciences developed through the years: DEVELOPMENTAL BIOLOGY: is the study of the growth and development of organisms. It is the study of life processes. Biologist study life processes in two ways. One is by studying the metabolic pathway is a cell (in vivo) and the other is by studying isolated portions of the cell in a test tube and simulating the normal environment of the cell (in vitro ).

11. LIFE SCIENCE The LIFE SCIENCES may be subdivided according to units of study: molecule, cell, organisms, or even population. The following divisions of life sciences developed through the years: ECOLOGY: is the study of all the interaction in the environment.

12. LIFE SCIENCE The LIFE SCIENCES may be subdivided according to units of study: molecule, cell, organisms, or even population. The following divisions of life sciences developed through the years: EMBYOLOGY: deals with the study of development of the embryo.

13. LIFE SCIENCE The LIFE SCIENCES may be subdivided according to units of study: molecule, cell, organisms, or even population. The following divisions of life sciences developed through the years: HISTOLOGY: is the study of tissues.

14. LIFE SCIENCE The LIFE SCIENCES may be subdivided according to units of study: molecule, cell, organisms, or even population. The following divisions of life sciences developed through the years: PHYSIOLOGY: Deals with the functions and activities of life and living matter.

15. PHYSICAL SCIENCE The PHYSICAL SCIENCE deals with matter and energy. Some of its subdivisions are: PHYSICS: the study of the interaction between matter and energy.

16. PHYSICAL SCIENCE The PHYSICAL SCIENCE deals with matter and energy. Some of its subdivisions are:

17. PHYSICAL SCIENCE The PHYSICAL SCIENCE deals with matter and energy. Some of its subdivisions are: CHEMISTRY: the study of the composition of matter and the changes it undergoes.

18. PHYSICAL SCIENCE The PHYSICAL SCIENCE deals with matter and energy. Some of its subdivisions are: ASTRONOMY: the study of heavenly bodies.

19. EARTH SCIENCE The EARTH SCIENCE ,also known as GEOSCIENCE , or the study of Earth and its neighbors, used to be a part of physical sciences. Now, it stands apart a Earth faces more and more critical problems. Earth science is further subdivided into specific fields of study, some of which are:

Now, it stands apart a Earth faces more and more critical problems. Earth science is further subdivided into specific fields of study, some of which are: PALEOLOGY: the study of prehistoric life through fossil remains.

22. EARTH SCIENCE The EARTH SCIENCE ,also known as GEOSCIENCE , or the study of Earth and its neighbors, used to be a part of physical sciences. Now, it stands apart a Earth faces more and more critical problems. Earth science is further subdivided into specific fields of study, some of which are: OCEANOGRAPHY: the study of the physical, chemical, and biological aspects of the oceans the ocean floor, mapping, and measuring of the Earth’s surface underwater.

23. EARTH SCIENCE The EARTH SCIENCE ,also known as GEOSCIENCE , or the study of Earth and its neighbors, used to be a part of physical sciences. Now, it stands apart a Earth faces more and more critical problems. Earth science is further subdivided into specific fields of study, some of which are: METEOLOGY: the study of the Earth’s weather and the atmosphere.
