| Term | Definition |
|---|---|
| Science | a way of learning about the natural world through observations and logical reasoning; leads to a body of knowledge. |
| Observing | the process of using one or more of your senses to gather information. |
| Inferring | the process of making an inference, an interpretation based on observations and prior knowledge. |
| Predicting | the process of forecasting what will happen in the future based on past experience or evidence. |
| Chemistry | the study of properties of matter and how matter changes. |
| Physics | the study of matter, energy, motion, and forces, and how they interact. |
| scientific inquiry | the diverse ways in which scientists study the natural world and propose explanations based on evidence they gather. |
| hypothesis | a possible explanation for a set of observations or answer to a scientific question; must be testable. |
| parameters | a factor that can be measured in an experiment. |
| manipulated variable | the one factor that a scientist changes during an experiment; also called independent variable. |
| responding variable | the factor that changes as a result of changes to the manipulated variable, or independent variable, variable in an expression; also called dependant variable. |
| controlled experiment | an experiment in which only one variable is manipulated at a time. |
| data | facts, figures, and other evidence gathered through observations. |
| communicating | the process of sharing ideas with others through writing and speaking. |
| model | physical, mental, visual, and other representations of an idea to help people understand a concept that they cannot observe directly. |
| scientific theory | a well tested explanation for a wide range of observations or experimental results. |
| scientific law | what scientists expect to happen every time under a particular set of conditions. |
| graph | a picture of information from a date table: shows the relationship between variables. |
| horizontal axis | (x-axis). a line that runs left to right along the bottom of a graph, on which the manipulated variable (or independent variable) is labeled. |
| vertical axis | (y-axis). a lien that runs up and down along the side of a graph, on which the responding variable (or dependant variable) is labeled. |
| origin | the (0, 0) point on a line graph, where the x-axis and y-axis cross line on a graph. |
| coordinant | a pair of numbers used to determine the position of a point on a graph. |
| data point | a point on a graph showing the location of a piece of data. |
| line of best fit | a smooth line that reflects the general pattern in a graph. |
| linear graph | a line graph in which the data points yields a straight line. |
| slope | the steepness of a line on a graph, equal to its vertical change divided by its horizontal change. |
| non linear graph | a line in which the data points don't fall along a straight line. |
| qualitative data | data that cant be measured and doesn't involve numbers. |
| quantitative data | data that involves numbers and / or can be measured. |
