Across
- 2. the symbol for the logarithm of the reciprocal of hydrogen ion concentration in gram atoms per liter, used to express the acidity or alkalinity of a solution on a scale of 0 to 14, where less than 7 represents acidity, 7 neutrality, and more than 7 alkalinity.
- 5. a graphic representation, as by curves, of a dependent variable, as temperature, price, etc.; graph.
- 8. a diagram representing a system of connections or interrelations among two or more things by a number of distinctive dots, lines, bars, etc.
- 11. a compound that reacts with an acid to form a salt, as ammonia, calcium hydroxide, or certain nitrogen-containing organic compounds.
- 13. pertaining to or concerned with quality or qualities.
- 16. to arrange or organize by classes; order according to class.
- 20. a systematic approach to acquiring new knowledge through observation and experimentation
- 22. a seeking or request for truth, information, or knowledge.
- 24. Often the scientific method the method of discovery used by scientists from the Enlightenment onward, in which a question is identified, data are gathered through observation and research, a hypothesis is formulated and then tested through experimentation, and the results are analyzed to draw a conclusion: usually followed, in the scientific community, by sharing the results so that others can attempt to replicate and confirm them independently.
Down
- 1. the science or technique of classification.
- 2. a measure of how acidic or basic (alkaline) a liquid is, on a scale typically from 0 to 14
- 3. to test or verify (a scientific experiment) by a parallel experiment or other standard of comparison.
