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?

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

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)

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

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

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

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

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

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

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.
