Term | Definition |
---|---|
Matter | anything that has mass and takes up space |
Mass | matter in an object |
Volume | the amount of liquid is something |
Weight | gravity pull on an object |
Dependent | a resulting factor in a controlled experiment that is observed and measured to see if it changes due to the manipulation of another variable |
control | a standard to which all other levels are compared in a scientific experiment |
experiment | a course of action completed in order to test a hypothesis |
variable | part of the experiment that changes |
constant | part of an experiment that is held in the same condition for control and experimental |
inference | not a fact, but an interpretation of what the direct observations mean |
scientific law | describes what scientists expect to happen eveytime under a particular set of conditions |
scientific theory | a well tested explanation for a wide range of observations or experimental result |
qualitative | made by gathering information that can be recorded using descriptive lauguage |
quanatitaive | made by gathering infomation that can be recorded as a number with a measurement unit |
inquire | to ask for information |
manipulated variable | a factor in a controlled experiment that is intentionally changed by the experimenter |
accuracy | how close a particular measurement is to the correct vaule |
calibration | to get something straight |
graduated cylinder | a tool used to measure liquid |
International System of Measurement | an internationally accepted system of physical units |
liquid | made up of tiny vibrating particles of matter, such as atoms, held together by intermolecular bonds. |
meniscus | the curve in the upper surface of a liquid close to the surface of the container or another object, caused by surface tension |
Newton | a unit of measurement |
precision | consistency of repeated measurement |
triple beam balance | a scale |
unit | units are standards for measurement of physical quantities that need clear definitions to be useful. Reproducibility of experimental results is central to the scientific method. A standard system of units facilitates this. |
