3. Objectives:
1. Explain that science involves asking
questions.
2. Describe the relationship of matter and
energy to physical science.
3. Describe the two branches of physical
science.
4. Identify three areas of science that use
physical science.
4. That’s Science!
Science is..
The process of gathering knowledge about the
natural world.
This is done through making observations and
asking questions
5. Physical science
study of matter and energy
Matter is the “stuff” everything is made of.
Energy is the ability to do work.
What is Physical Science?
6. Learning about matter and energy will help
you answer questions such as:
1. Why will paper burn but gold will not?
2. Why is it harder to throw a bowling ball than a
baseball?
3. How can water turn into steam and back into
water?
7. Branches of Physical
Science: Physical science is usually divided into:
Chemistry
○ The study of all forms of matter, including how matter
interacts.
Physics
○ Looks mostly at energy and how energy affects
matter.
8. Other related sciences:
Meteorology
The study of the Earth’s atmosphere, especially
weather and climate.
Meteorologists must understand High and Low
pressure, motion, and force before they can predict
the weather.
9. Geology
The study of the origin, history, and structure of Earth.
Geochemists are geologists who apply their
knowledge of heat, force, and chemistry to
understand how rocks and soil change over time.
10. Biology
The study of life. Chemistry and physics explain
many things that happen in biology.
A chemical reaction explains how animals use sugar
and oxygen to produce carbon dioxide and water
and to release energy.
