| Question | Answer |
|---|---|
| the study and investigation and exploration of natural events, and of the new information that results. | SCIENCE |
| the study of physics, chemistry, matter and energy. | PHYSICAL SCIENCE |
| the study of the Earth's processes inside and outside of Earth. | EARTH SCIENCE |
| the study of living things, all organisms, and the many processes that occur within them. | LIFE SCIENCE |
| the result of using one or more of your senses to gather information and take notice of what occurs | observation |
| a logical explanation of an observation that is drawn from prior knowledge or experience | inference |
| a possible explanation for an observation that can be tested by scientific investigations | hypothesis |
| a statement of what will happen next in a sequence of events as what is considered in the hypothesis is tested | prediction |
| designed to test predictions from a hypothesis; repeatable steps that will lead to measureable data | experiment |
| use of a data table compiled into a graph to review results from an experiment | analyze results |
| draw a conclusion after analyzing results that supports, proves or disproves a hypothesis in which the results tested are consistent | conclusion |
| communicate results of an experiment by exchanging information online, sharing in professional journal articles, or in a speech at a scientific conference | communicate |
| an explanation of observations of events that is based on knowledge gained from observations and investigations | scientific theory |
| a rule that describes a repeatable pattern in nature; not an explanation of why or how but only states that it will happen | scientific law |
| the practical use of scientific knowledge, especially in industrial or commercial use | technology |
| comparing what is known with new information to agree or disagree | critical thinking |
| to doubt the truthfulness of something | skepticism |
| cannot be proven to be true or false | Opinions |
| procedures, precautions, and prevention as well as knowledge of safety symbols and recognizing potential hazards | safety |
| written summmary statements including specificas, measurements, and or results | description |
| interpretation of observations | explanation |
| System'e International'e - an internationally accepted metric measurement system | International System of Units (SI) |
| mega, kilo, hecto, deka [meter, liter, gram] deci, centi, milli, macro, nano | SI Prefixes |
| an expression of error as a percentage of the accepted value | Percent Error |
| favor for or against of a preferred outcome | bias |
| uses words to describe what is observed | qualitative data |
| uses numbers to describe what is observed | quantitative data |
| any factor that can have more than one value | variable |
| the factor you wish to test, the one that will be changed to determine an outcome | independant variable |
| the factor you measure to observe an outcome | dependant variable |
| factors that do not change in an experiment, that will stay the same for all trials | constants |
| uses the same factors as the experiment but the independant variable is not changed | control group |
| used to study how a change in the independent variable will affect the dependant variable measurement | experimental group |
| science journal, balances, thermometers, calculators, computers, scales, hot plate, test paper (litmus or pH), stop watches | typical science tools |
| physical model - see and touch, mathematical model - numerical data of an event or idea, computer simulation - combination of data and mathematical models with computer simulation or animation | Models |
| Data makes sense with some variation within a small range | Reasonable Data |
| Data that do not fit with the rest of a data set | Anomalous Data |
| Line graphs to display continuous numerical data, Bar graphs display both numerical and categorical data, Circle graph demonstrates a visual of category percentages. | Graphs |
| used to see a correlation between two varibles where changes in one variable results in a change and vice versa, not causation | scatter plots |
| number of times an event occurs in a given period | frequency distributions |
| visually displays continuous ranges of frequency distributions | histograms |
| a working model, subject to revisions, troubleshooting or trade offs | prototype |
| identify a need, research the problem, design a solution, brainstorm ideas, document process, create, test and evaluate a prototype, troubleshoot and redesign, communicate solution | design process |
