Science Skills
Science VS Technology
A. Science is a system of knowledge and the methods
you use to find that knowledge.
B. Technology is the use of knowledge to solve practical
problems.
a. The goal of science is to expand knowledge to
solve practical problems.
b. The goal of technology is to apply that
knowledge.
Interdependent
C. Science and Technology are
interdependent.
a. What does that mean?
1. It means advances in one lead to
advances in the other.
Ex. Advances in energy will lead to advances
in items that use energy. Such as gasoline to
ethanol.
The Study of Science
D. The study of science is broken up into two
main branches. Social Science and Natural
Science.
a. Natural science is broken up into three
different branches. Physical science, Earth
and Space Science, and Life Science.
Branches of Physical Science
E. The two main branches of physical science are
chemistry and physics.
a. Chemistry is the study of the composition,
structure, properties, and reactions of matter.
b. Physics is the study of matter and energy and the
interactions between the two through forces and
motion.
c. The application of physics and chemistry to the
study of Earth is called Earth Science.
Branches of Science
F. Other branches include Geology (the
study of the origin, history, and
structure of Earth), Astronomy (the
study of the universe beyond Earth),
Biology (the study of living things).
Branches of Science
E. Just because Science is broken up into
different parts doesn’t mean that each
part is limited to its own branch. Many
branches of science overlap one
another. Such as biophysics.
Big Ideas of Physical Science
 There are four big ideas of physical science.
 They include:
 Space and Time
 Matter and Change
 Forces and Motion
 Energy
Space and Time
 The universe is about 13,700,000,000 years old.
 13.7 Billion Years Old
 The observable universe is about
700,000,000,000,000,000,000,000,000 meters in
diameter.
 700 million billion billion meters in diameter.
 The diameter of the earth is only 12,700,000 meters.
 Twelve million seven hundred thousand meters
Matter and Change
 A very small amount of the universe is made up of
matter.
 Matter has volume and mass.
 Matter can exist in different states: Solid, Liquid,
Gas.
 All matter is made up of atoms.
 Atoms are made up of electrons, protons, and
neutrons.
Forces and Motion
 A force is a push or a pull.
 A force causes motion.
 A change in motion can be described as
causing a resting object to move, speed up
or slow down a moving object, or a change
in an objects direction.
Energy
 Energy exists in many forms.
 Kinetic, potential, chemical, and thermal are some
examples of different forms of energy.


Kinetic energy is the energy of an object in motion.
Potential energy is the stored energy of an object.
 Energy exists in matter and can be absorbed or released
during a reaction.
 Matter can also be changed into energy or can be
transferred between objects.
