Physical science 8
| Question | Answer |
|---|---|
| Qualitative observation | An observation you use with your five senses. |
| Quantitative observation | AN observation you use with numbers. |
| Inference | an interpretation based on observations and prior knowledge |
| Volume | the amount of space that matter occupies |
| Data | facts, figures, and other evidence gathered through observations |
| Energy | the ability to do work or cause change |
| Hypothesis | a possible explanation for a set of observations or answers to a scientific question |
| Mass | a measure of how much matter is in an object |
| Matter | anything that has mass and occupies spac |
| Observing | the process of using one or more of your senses to gather information |
| Scientific Inquiry | the ongoing process of discovery in science-Research-Hypothesis-Experiment-Analyze data-Conclusion-Communicate |
| Scientific law | a statement that describes what scientists expect to happen every time under a particular set of conditions |
| Scientific theory | well tested explanation for a wide range of observations or experimental results |
| Variable | a factor that can change in a experiment |
| Work | force exerted on an object causing it to move |
| Weight | measure of force gravity has on an object |
| ACCURACY | the quality or state of being correct or precise |
| calibration | the action or process of calibrating an instrument or experimental readings |
| graduated cylinder | A graduated cylinder, measuring cylinder or mixing cylinder is a piece of laboratory equipment used to measure the volume of a liquid. Graduated cylinders are generally more accurate and precise than laboratory flasks and beakers |
| international system of measurment | The International System of Units is the modern form of the metric system and is the world's most widely used system of measurement, used in both everyday commerce and science |
| liquid | having a consistency like that of water or oil, i.e., flowing freely but of constant volume. |
| mass | a coherent, typically large body of matter with no definite shape. |
| matter | physical substance in general, as distinct from mind and spirit; (in physics) that which occupies space and possesses rest mass, especially as distinct from energy. |
| meniscus | the curved upper surface of a liquid in a tube. |
| newton | the SI unit of force. It is equal to the force that would give a mass of one kilogram an acceleration of one meter per second per second, and is equivalent to 100,000 dynes |
| precision | the quality, condition, or fact of being exact and accurate. |
| triple beam balance | he 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 | 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 | volume definition. In mathematics, the amount of space occupied by an object measured in three dimensions, expressed in cubic units. In physics, the loudness of a sound. |
| weight | weight is the force exerted on a body by gravity. |
