Science and technology are interdependent - advances in one lead to advances in the other CHEMISTRY – the study of the composition, structure, properties and reactions of matter ● PHYSICAL SCIENCE is made up of chemistry (semester 1) and physics (semester 2) ● EARTH AND SPACE SCIENCE is made up of geology (the study of the origin, history and structure of the earth) and astronomy (study of the universe) PHYSICS – the study of matter and energy ● LIFE SCIENCE –the study of living things is known as and the interactions between the two BIOLOGY… through forces and motion 1 8/18/2014 The Big Ideas of Physical Science SCIENTIFIC APPROACH An organized plan for gathering, organizing and communicating space and time information is a SCIENTIFIC matter and change METHOD. forces and motion The goal of any scientific energy method is to solve a problem or to understand an event. SCIENTIFIC METHOD SCIENTIFIC METHOD making observations OBSERVATION: information forming a hypothesis that is obtained through the testing the hypothesis senses. drawing conclusions HYPOTHESIS: a proposed answer to a question. developing a theory SCIENTIFIC LAW A SCIENTIFIC LAW describes on observed pattern in nature without attempting to explain it - the explanation of such a pattern is provided by a SCIENTIFIC THEORY. 2 8/18/2014 3.
