Qualitative | Made by gathering information that can be recorded using descriptive language |
Quantitative | Made by gathering information that can be recorded as a number with a measurement unit |
Inference | Not a fact, but a interpretation of what the direct observations mean |
scientific law | Describes what scientists expect to happen every time under a particular set of comditions |
Constant | Part of an experiment that is held in the same condition for control and experimental |
Varible | Part of an experiment that changes |
Independent variable | A factor in a controlled experiment that is intentionally changed by the experimenter |
Theory | A well tested explanation for a wide range of observations or experimental results |
Inquire | To ask for informatin |
Responding varible | A resulting factor in a controlled experiment that is observations and measured to see if it changes due to the manipulation of another variable |
Experiment | A course of action completed in order to a test a hypothesis |
Control | A standard to which all other levels are compared in a scientific experment |
Matter | Anything that has mass and takes up space |
Physical change | Any change that alters form or appearance of matter but does not make any substance in the matter in to a different substance |
Chemical change | Any change that changes the inside of something, but stays the same on the outside. |
accuracy | the quality or state of being correct or precise. |

Newton | A unit of measurment |
precision | the quality, condition, or fact of being exact and accurate. |
Triple beam balance | typical mechanical balance |
unit | an individual thing or person regarded as single and complete but which can also form an individual component of a larger or more complex whole. |
Volume | the amount of space that a substance or object occupies, or that is enclosed within a container, especially when great. |
weight | a body's relative mass or the quantity of matter contained by it, giving rise to a downward force; the heaviness of a person or thing |
