- 3. can be used to describe objects, conditions, events, or changes that might be occurring
- 5. symbols are used in an equation, a statement that describes a relationship where the quantities on one side of the equal sign are identical to the quantities on the other side
- 7. system developed from earlier Greek and Roman methods of measurement
- 10. experiment compares two situations in which all the influencing factors are identical except one
- 17. proportion when two variables increase (or decrease) together in the same ratio, they are said to be in direct proportion
- 18. is a relationship between two numbers that is obtained when one number is divided by another number
- 19. "pseudo" means fals; a deceptive practice that uses the appearance or language of science to convince, confuse, or mislead people into thinking that something has scientific validity when it does not
- 21. principle describes a more specific set of relationships than is usually identified in a law
- 22. properties cannot be defined in simpler terms other than to describe how it is measured
- 23. system was established by the French Academy of Sciences in 1791
- 24. proportion other common relationships include one variable increasing in proportion to the square or to the inverse square of a second variable
- 27. is a process of comparing a property to a well-defined and agreed-upon referent
- 28. is defined as the mass of a particular cylinder made of platinum and iridium, kept by the International Bureau of Weights and Measures in France
- 29. defines a metric unit that is commonly used to measure liquid
Down
- 1. means the extent of a surface, and each cube has six surfaces, or faces (top, bottom, and four sides)
- 2. refers to a specific quantity of an object or event that can have different values
- 3. defined as mass per unit volume
- 4. that you refer to, or think of, a given property in terms of another, more familiar object
- 6. a tentative thought-or experiment-derived explanation
- 8. was originally defined as 1/86,400 of a solar day (1/60 x 1/60 x 1/24)
- 9. broad working hypothesis that is based on extensive experimental evidence
- 11. well-defined and agreed-upon referent is used as a standard called a unit
- 12. the symbols actually represent quantities, or measured properties
- 13. means how much space something occupies and size being described
- 14. qualities or attributes that, taken together, are usually peculiar to an object
- 15. constant to make a statement of proportionality into an equation, you need to apply a proportionality constant, which is sometimes given the symbol k
- 16. a re-creation of an event or occurrence in a way that enables a scientist to support or disprove a hypothesis
- 20. unit makes it possible to communicate and duplicate measurements
- 25. constant Numerical constant-A proportionality constant in an equation might be a numerical constant, a constant that is without units
- 26. description of a theory or idea that accounts for all known properties
- 27. is defined as the distance that light travels in a vacuum during certain time period, 1/299,792,458 second
