Physical Science

Chapter 1

presupposition unproven idea; used as basis to prove other ideas
worldview outlook in the way you view life; NOT ATTITUDE; there are 2 worldviews: Christian and humanism/secularist
Christian worldview has 3 suppositions: 1. God made the world and man, 2. The world is fallen because of sin, 3. God works to redeem the world.
humanism/secularist worldview has 4 presuppositions: 1. The universe always existed, 2. People are just evolved by animals, 3. Death is normal, 4. Scientism
Creation Mandate exercise dominion; best use of resources
Bible establishes science and gives it reason to exist, shows us why we should study the world, we can know how to better use its resources
scientism belief that we can know things best with science; "science will solve the worlds problems; Job 5:7
Science isn't... source of final answers or truth, going to give us correct view of world, completely objective, always based on direct observations
theory tells why things happen
law describes what happens
model simplified depiction of complex object or concept; can be physical or conceptual; it isn't "true" but a simplification; goal is workability, not accuracy
historical science (origins science) scientific study of evidence for origins of physical and living things in the world
inference the past is the key to the present
paradigm a way of thinking; a mindset or a worldview; determines the activities and actions of a scientist
hypothesis educated guess; temporary explaination of an object or event
Physical Science made up of 2 areas: physics and chemistry
science studying physical universe, so we can wisely use it
scientific method 1. pose a question, 2. suggest a hypothesis, 3. collect data (info), 4. evaluate hypothesis, 5. report conclusions, 6. develop theory
data analysis after data is collected it is analyzed to determine how it relates to the hypothesis
loving neighbor with science serving, preventing diseases, and energy
loving God with science submitting, glorifying Him, adoring His greatness and goodness in His creation, displaying His greatness and goodness through our work
model vs truth remember, science produces models, not truth
2 areas of science basic or theoretical: finding info, and applied: using new knowledge
what scientist do operational science: research, historical science: origins, and teaching science: consultation
data mining reviewing studies that have been published in order to find data that can be used
collection taking examples from nature for study; example: insect collection
survey sampling or partial collection of info from a collection or group
qualitative data descriptions

How do you collect data? data mining, collection, survey, waiting for opportunity, trial and error, and controlled experiment
controlled experiment 1 variable altered at a time
