| Term | Definition |
|---|---|
| Qualitative | made by gathering information that can be recorded using (descriptive language)(5 senses) |
| Quantitative | 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 observation means. |
| Scientific Law | describes what scientists expect what the direct observation means. |
| Coanstant | part of a experiment that is held the in the same condition for control and experimental. |
| Variable | part of the experiment that changes. |
| Manipulated Variable | a factor in a controlled experiment that is intentionally changed by the experiment. |
| Scientific theory | a well tested explanation for a wide range of observations or experimental results. |
| Inquiry | to ask for information. |
| Dependent 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. |
| Expierment | 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. |
| Physical Change | when the form of the object changes but it does not make the object disappear. |
| Chemical Change | a change in matter that produces one or more new substances. |
| Weight | the amount of gravity on an object. |
| Mass | the amount of matter in an object. |
| units of mass | grams |
| Calculating volume | volume = length x width x height |
| Accuracy | the condition or quality of being true, correct, or exact; freedom from error or defect; precision or exactness; correctness. |
| Calibration | to determine, check, or rectify the graduation of (any instrument giving quantitative measurements). |
| Graduated cylinder | a narrow, cylindrical container marked with horizontal lines to represent units of measurement and used to precisely measure the volume of liquids. |
| International system of measurement | international decimal system of weights and measures derived from and extending the metric system of units. |
| Liquid | composed of molecules that move freely among themselves but do not tend to separate like those of gases; neither gaseous nor solid. |
| Mass | usually of indefinite shape and often of considerable size: |
| Matter | the substance or substances of which any physical object consists or is composed: |
| Meniscus | a crescent or a crescent-shaped body. |
| Newton a- unit of measurement | One newton is equal to the force needed to accelerate a mass of one kilogram one meter per second per second. |
| Prescision | the state or quality of being precise. |
| Triple beam balance | Triple Beam Balance is a typical mechanical balance. It has a beam which is supported by a fulcrum. On one side is a pan on which the object is placed. On the other side, the beam is split into three parallel beams , each supporting one weight. |
| Unit | a single thing or person. |
| Volume | the amount of space, measured in cubic units, that an object or substance occupies. |
| Weight | the amount or quantity of heaviness or mass; amount a thing weighs |
| Matter | Anything that has mass and volume. (takes up space). |
| Pure substance | A substance made of only one kind of material having definite proportional amounts and properties. |
| Mixture | Matter that consists of two or more substances not chemically combined |
| Element | The simplest type of pure substances |
| Compound | Two or more substances not chemically combined |
| Homogeneous mixture | Two or more substances not chemically combined, but appearing to be evenly blended |
| Heterogeneous mixture | Two or more substances not chemically combined, and appearing non-uniform with physically distinct substances included. |
