science
| 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. |
