Exploring Physical Science Section 1
That’s Science l Science is the process of gathering knowledge about the natural world l l 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 l Physical science is the study of matter and energy l l Matter is the stuff everything is made of Energy is the ability to do work l All moving objects have energy § Example – food ( stored energy)
l Physical Science l Study of matter and energy l l How they relate to each other Divided into 2 branches l l Chemistry physics
l Chemistry is the study of all forms of matter including how matter interacts with other matter l Looks at the structure and properties l How they behave under conditions § § l Temperature Pressure Studies how substances change l 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
l Physics deals with matter; mostly the way energy affects matter l l Study different forms of energy l Motion l Force l Gravity l Electricy l Light l magnetism l heat Energy can make matter do some interesting things
Physical Science: All Around You l Meteorology l Study of the Earth’s atmosphere, especially in relation to weather and climate l l Meteorologist is a person who studies the atmosphere Common careers are weather forecasts § l Tornado chasers Must have knowledge of physical science § § § Pressure Motion forces
l Geology l The study of the origin, history and structure of the Earth l 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
l Biology l Physical science and life science are related l Physics and chemistry explain many things that happen in biology § Examples § Get energy from food § Photosynthesis § Respiration
