Chapter 1

Modeling Our Orderly World 1A Order In Our World What is Physical Science

God created the universe with order because He is a God of order / 1B

Studying Science Why do we do science

==Creation Mandate==

the command given in Genesis 1, instructing man to fill the earth and have dominion over it / How do we decide whether or not a particular use of science is right or wrong

Human Prospering A Thriving Creation Glorifying God / Biblical Motivations

How can I grow through this decision

science

the systematic study of the universe to produce observations interferences, and models

You can convert between any two units of measures as long as you know the ==conversion factor== / Unit Analysis 1. write the value that you already know 2. write the conversion factor which should be a factor NOTE

the old unit does in the denominator 3. cancel your units 4. calculate the answer by multiplying and dividing / How it works Balances and scales o both balances and scales basically weigh things, but use slightly different dimensions o a balance measures ==mass==, while a scale measures ==height== o a balance works like a seesaw, balancing an unknown mass with a known mass o a scale measures force due to gravity (weight) o a scale uses a spring system to determine the amount of force being applied

physical science

the study of matter and energy and the interactions between them

chemistry

the study of the composition, structure, and properties of matter as well as changes in matter

creation mandate

the command given in Genesis 1, instructing man to fill the earth and have dominion over it

ethics

a system of moral values or a theory of proper conduct

model

a workable explanation or description of a phenomena

physics

the study of matter and energy and the interactions between them

theory

a model that explains a related set of phenomena

law

a model that describes phenomena under certain conditions * It does not attempt to explain the phenomena

scientific inquiry

an ongoing, orderly, cyclical approach used to investigate the world

workability

the basis upon which a model is assessed, taking into account how well it explains or describes a set of observations and how well the model makes predictions

hypothesis

an initial, testable explanation of a phenomenon that stimulates and guides the scientific investigation

qualitative data

based on words and is obtained by observation

quantitative data

based on numbers and is obtained by measuring measurement

accuracy

comparison of a measurement to an accepted or expected value

precision

degree of exactness of a measurement
