Chapter 1: PS
This is a review over chapter one in the Physical Science 6th edition textbook.
| Question/ term | Answer/definition | |
|---|---|---|
| Define Forensic Scientists | Collect evidence and conduct investigations to determine what occurred during a crime | |
| Define Phenomena | a fact or situation that is observed to exist or happen, especially one whose cause or explanation is in question. | |
| How does physical science relate to other sciences? | Life science and earth science overlap under categories of mineralogy, astronautical engineering, and geophysics. | Life science and physical science overlap under the categories of biochemistry, nutrition, biophysics, pharmacology |
| Define Science | The systematic study of the universe to produce observations, inferences, and models. | |
| Why can we study the universe systematically? | If phenomena were completely random, we would have to accept just watching events happen but investigating them would be impossible. | |
| Define the Law of Cause and Effect | every effect has a specific, identifiable cause, and for every cause, there is a definite and predictable effect. | |
| Define the principle of uniformity of nature | nature acts the same today as it did yesterday and we can fully expect it to act the same way tomorrow. | |
| Where does order come from? | God created all things out of nothing, as seen in Genesis. | |
| Does God need a cause for existance? | No, because the law of cause and effects only relates to everything IN OUR WORLD. God existed before all things, and so he is not and can not be characterised under the law of cause and effect. | |
| Define Worldview | Our view of the world on the basis of assumptions we have about the world. | |
| Define secular science | Science that assumes there is no God, and we were all created through the process of evolution. | |
| Define Religious worldview | People who view the world through the lense of the teaching of a particular teacher or text. | |
| Define Christian Mandate | Gods commandment to humans about exercising wise and good dominion over His creation for the glory of God and the benefit of their fellow humans. | |
| How do we follow the christian mandate? | Studying and caring for God's creation. | |
| Define Ethics | A system of moral values of a theory of proper conduct. | |
| What 3 things should christian ethics be based upon? | Biblical principles, biblical outcomes, and Biblical motivations. | |
| Define Model | a workable explanation or description of a phenomenon | |
| Define Theory | a model that explains a related set of phenomena | |
| Define law | a model, often expressed as a mathematical equation that describes a phenomena under certain conditions. | |
| Define Workability | a fact or situation that is observed to exist or happen, especially one whose cause or explanation is in question. | |
| Define scientific inquiry | An ongoing, orderly, cyclical approach used to investigate the world. | |
| Define observation | the central activity in science (first step in the scientific inquiry | |
| Define posing questions | A fundamental skill for scientists that gives them their purpose for doing science (second step in scientific inquiry) | |
| Define research | Done when faced with a new question that a scientist needs to determine what others already know until they have enough information to focus on their investigation on aspects of the issue that are not well understood (third step in scientific inquiry) | |
| Define hypothesis | an initial, testable explanation of a phenomenon that stimulates and guides the scientific investigation. (Fourth step in scientific inquiry) | |
| Define investigation | where a scientist designs an experiment to address the hypothesis that they formed on the basis of their questions. (fourth step in scientific inquiry) | |
| Define Analysis | sixth step in scientific inquiry that involves graphing, reasoning, and using mathematics. | |
| Define conclusion | The 7th step in the scientific inquiry that connects all the previous activities. | |
| Define Communication | The final step in scientific inquiry; peer review, where models are strengthened, modified, or even distorted. | |
| Define measurements | Quantitative; based on numbers or quantities | |
| Define SI | the International system of units | |
| Define derived units | A mathematical combination of two or more base units | |
| m | meter (length) | |
| kg | kilogram (mass) | |
| s | seconds (time) | |
| A | ampere (measure electric current) | |
| K | kelvin (temperature) | |
| mol | mole (amount of a substance) | |
| cd | candela (intensity of light) | |
| Define accuracy | Compares a measurement to the accepted or expected value of a measurement | |
| Define precision | The degree of exactness of the measurements |
