| Question | Answer |
|---|---|
| Qualitative Observations | made by gathering information that can be recorded using descriptive language |
| Quantitative Observations | made by gathering information that can be recorded as a number with a measurement unit |
| Inference | not a fact, but an interpretation of what the direct observations mean |
| Scientific Law | describes what scientists expect to happen every time under a particular set of conditions |
| Constant | part of an experiment that is held in the same condition for control and experimental |
| Variable | part of the experiment that changes |
| Manipulated/Independent Variable | a factor in a controlled experiment that is intentionally changed by the experimenter |
| Scientific Theory | a well tested explanation for a wide range of observations or experimental results |
| Inquire | to ask for information |
| Dependent/Responding Variable | a resulting factor in a controlled experiment that is observed and measured to see if it changes due to the manipulation of another variable |
| Experiment | a course of action completed in order to test a hypothesis |
| Control | a standard to which all other levels are compared in a scientific experiment |
| Matter | anything that has mass and takes up space |
| Mass | matter in an object DOES NOT CHANGE |
| Weight | gravity's pull on an object DOES CHANGE |
| Volume | amount of space an object takes up length x width x height L x W x H |
| Physical Properties | any change that alters form or appearance of matter but does not make any substance in the matter into a different substance |
| Chemical Properties | a change in matter that produces one or more new substances |
| accuracy | the degree to which the result of a measurement, calculation, or specification conforms to the correct value or standard |
| calibration | each of a set of graduations on a measurement |
| graduated cylinder | a graduated cylinder is a piece of lab equipment used to measure the volume of a liquid |
| International System of Measurement | (abbreviated as SI) is the most common system of measurement used, it's known as the metric system |
| liquid | one of the four states of matter |
| meniscus | the dip of the liquid in a graduated cylinder |
| Newton- a unit of measurement | is an SI unit of force. |
| precision | exactness, the ability of a measurement to be consistently produced |
| triple beam balance | is a typical mechanical balance |
| unit | a particular amount of length, time money, etc. that is used as a standard for counting or measuring |
