branches of science

2. Science
Science is more about gaining knowledge than it is
about simply having knowledge. Science is a way of
learning about the natural world that is based on
evidence and logic. In other words, science is a
process, not just a body of facts. Through the process
of science, our knowledge of the world advances.

3. Science
• It comes from the Latin word scientia, which
means “to know”.
• It is a systematic attempt to establish knowledge
that helps explain natural and physical
occurrences through objective means.

6. Classification of Science
1. Pure Science – It involves gathering information through experimentation,
which is done mainly for the pursuit of knowledge.
2. Applied Science – It deals with the search for practical uses of scientific
knowledge and scientific laws.
3. Technology – It comes from the Greek word tekne that means “art, craft or
skill” and logos that means “word or expression”. It is defined as the
application of science.

7. Branches of Science
1. Life Science – It is also known as biology. It
studies all aspects of living things.
Subdivisions of Life Sciences
a. Botany – It is the study of plants.
b. Zoology – It is the study of animals.

8. c. _____________– It is the study of the function and
behavior of genes.
d. ____________– It is the application of biological
knowledge to human health.
e. __________– It aims to understand the properties,
structure, activities, and functions of the cell.
f. _________________– It is the study of the growth and
development of organisms.
Genetics
Biomedicine
Cellular biology
Developmental biology

9. g. Ecology – It is the study of populations of organisms in
their natural habitats.
h. Embryology – It deals with the study of the development
of the embryo.
i. Histology – It is the study of tissues.
j. Molecular biology – It studies the molecular basis of
biological functions.
k. Physiology – It deals with the functions and activities of
life and living matter.

10. 2. Physical Science – It deals with matter and energy.
Subdivisions of Physical Science
a. Physics – It is the study of the interaction
between matter and energy.
b. Chemistry – It is the study of the composition of
matter and the changes it undergoes.
c. Astronomy – It is the study of heavenly bodies.

11. 3. Earth Science – It is the study of Earth and
its neighbors.
Subdivisions of Earth Science
a. Geology – It is the study of the history and
structure of Earth.
b. Paleontology – It is the study of prehistoric
life through fossil remains.

12. c. Oceanography – It is the study of the physical,
chemical, and biological aspects of the oceans
and the ocean floor, mapping, and measuring of
Earth’s surface under water.
d. Meteorology – It is the study of Earth’s weather
and atmosphere.
e. Petrology – It is the study of rocks.
Oceanography –
Meteorology –
Petrology –

13. Physical science is the study of matter
and energy. That covers a lot of territory
because matter refers to all the “stuff” that
exists in the universe. It includes everything you
can see and many things that you cannot see,
including the air around you. Energy is also
universal. It’s what gives matter the ability to
move and change. Electricity, heat, and light are
some of the forms that energy can take.
