Term | Definition |
---|---|

science | the study of 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 the properties of matter and how matter changes |

physics | the study of matter,energy,motion, and forces and how they interact |

scientific inquiry | the ongoing process of discovery in science |

hypothesis | a possible explanation for a set of observations or answer to a scientific question |

parameter | a factor that can be measured in an experiment |

manipulated variable | the one variable parameter that a scientist changes during an experiment |

responding variable | the variable parameter that changes as a result of changes to the manipulated, or independent, variable in an experiment |

controlled experiment | an experiment in which only one parameter is manipulated at a time |

data qualitative | has no numbers or measurements |

data quantitative | has measurements and numbers |

communicating | the process of sharing ideas with others through writing and speaking |

model | a representation of an object or process |

scientific theory | a well-tested explanation for a wide range of observations or experimental results |

scientific law | a statement the describes what scientist expect to happen every time under a particular set of conditions |

graph | a picture of information from a data table; shows the relationship between variables |

horizontal axis | a line that runs left to right along the bottom of a graph, on which the manipulated variable is labeled |

vertical axis | a line that runs up and down along the side of a graph, on which the responding variable is labeled |

origin | the point on a line graph; where the x-axis and y-axis cross on a graph |

coordinate | 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 |

slope | the steepness of a line on a graph, equal to its vertical change divided by its horizontal change |

nonlinear graph | a line graph in which the data points do not fall along a straight line |

linear graph | a line graph in which the data points yield a straight line |

data | facts,figures, and other evidence gathered through observations |
