Scientific Inquiry
Term | Definition |
---|---|
Qualitative Observations | 1. made by gathering information that can be recorded using descriptive language |
Quantitative Observations | 2. made by gathering information that can be recorded as a number with measurement unit. |
Inference | 3. not a fact, but an interpretation of what the direct observation mean |
Scientific law | 4. describes what scientists expect to happen every time under a particular set of conditions |
Constant | 5. part of an experiment that is held in the same condition for control and experimental |
Variable | 6. part of the experiment that changes |
Manipulative variable | 7. a factor in a controlled experiment that is intentionally changed by the experimenter |
Scientific Theory | 8. a well tested explanation for a wide range of observations or experimental results |
Inquire | 9. to ask for information |
Responding variable | 10. a resulting factor in a controlled experiment that is observed and measured to see if it changes due to the manipulation of another variable |
Expirement | 11. a course of action completed in order to test a hypothesis |
Control | 12. a standard to which all other levels are compared in a scientific experiment |
Newton or N | 13. a unit of force required to move 1 kilogram 1 meter squared |
Gravity | 14. force that pulls object towards each other |
Accuracy | 15. the degree to which the result of a measurement, calculation, or specification conforms to the correct value or a standard. plural noun: accuracies |
Calibration | 16. each of a set of graduations on an instrument |
Graduated cylinder | 17.A graduated cylinder, measuring cylinder or mixing cylinder is a piece of laboratory equipment used to measure the volume of a liquid. |
International System of Measurement | 18.The definitions of the other base units are more complicated. The International System of Units (abbreviated SI from French: Le Système International d'Unités) is the modern form of the metric system and is the world's most widely used system of measur |
Liquid | 19. a state of matter having definite volume, indefinite shape, with particles touching, and sliding around each other |
Mass | 20. the amount of matter (atoms) in a substance |
Matter | 21. anything that has mass and takes up space |
Meniscus | 22. the curved upper surface of a liquid in a tube |
Newton-a unit of measurement | 23. The SI derived unit used to measure force. One newton is equal to the force needed to accelerate a mass of one kilogram one meter per second per second. See also joule. Newton, Sir Isaac 1642-1727. |
Precision | 24. refinement in a measurement, calculation, or specification, especially as represented by the number of digits given. |
Triple beam balance | 25. The triple beam balance is used to measure masses very precisely; the reading error is 0.05 gram. |
Unit | 26. 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 | 27. the amount of space that a substance or object occupies, or that is enclosed within a container, especially when great. |
Weight | 28. a body's relative mass or the quantity of matter contained by it, giving rise to a downward force; the heaviness of a person or thing. |
Pure substance | 29. a substance made of only one kind of material having definite proportional amounts and properties |
Element | 30. the simplest type of pure substance |
Homogeneous mixture | two or more substances not chemically combined, but appearing to be evenly blended |
