Scientific Inquiry

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
