3. Bell Ringer
One afternoon you decide to pop some popcorn. You put the bag in the microwave, but after a couple of minutes of cooking, it is clear the popcorn is not popping. Why did this happen? What steps could you take to help locate the problem?

4. That’s Science
Science is the process of gathering knowledge about the natural world
Starts with a question
Everyday actions involve using your knowledge of science
Making observations and asking questions is what science is all about
There are many branches of science, including physical science

5. What is Physical Science?
Physical science is the study of matter and energy
Matter is the stuff everything is made of
Energy is the ability to do work
All moving objects have energy
Example – food ( stored energy)

6. Physical Science Study of matter and energy Divided into 2 branches
How they relate to each other
Divided into 2 branches
Chemistry
physics

7. Chemistry is the study of all forms of matter including how matter interacts with other matter
Looks at the structure and properties
How they behave under conditions
Temperature
Pressure
Studies how substances change
A chemical reaction takes place when one substance reacts with another substance to produce a new substance
Chemical reactions take place all the time
Digest food
Start the car
Turn on a flashlight

8. Physics deals with matter; mostly the way energy affects matter
Study different forms of energy
Motion
Force
Gravity
Electricy
Light
magnetism
heat
Energy can make matter do some interesting things

9. Physical Science: All Around You
Meteorology
Study of the Earth’s atmosphere, especially in relation to weather and climate
Meteorologist is a person who studies the atmosphere
Common careers are weather forecasts
Tornado chasers
Must have knowledge of physical science
Pressure
Motion
forces

10. Geology The study of the origin, history and structure of the Earth
Some geologists are geochemists
Geochemists are scientists who study the chemistry of rocks, minerals and soil
Must have knowledge of physical science
Chemistry
Heat
force

11. Biology Physical science and life science are related
Physics and chemistry explain many things that happen in biology
Examples
Get energy from food
Photosynthesis
Respiration

12. Summary
Science is a process of gathering knowledge about the natural world.
Physical science is the study of matter and energy.
Physical science is divided into the study of physics and chemistry.
Chemistry studies the structure and properties of matter and how matter changes.
Physics looks at energy and the way that energy affects matter.
A knowledge of physical science is important for many areas of science, such as geology and biology.
