Across
- 3. apparatus- laboratory equipment
- 7. variable- a variable (often denoted by y ) whose value depends on that of another.
- 8. the real physical matter of which a person or thing consists and which has a tangible, solid presence.
- 12. intellectual and practical activity encompassing the systematic study of the structure and behavior of the physical and natural world through observation and experiment.
- 13. a diagram showing the relation between variable quantities, typically of two variables, each measured along one of a pair of axes at right angles.
- 14. Factor- an arithmetical multiplier for converting a quantity expressed in one set of units into an equivalent expressed in another.
- 15. units- A system of measurement in which the basic units are the meter, the second, and the kilogram.
- 16. analysis- analysis using the fact that physical quantities added to or equated with each other must be expressed in terms of the same fundamental quantities (such as mass, length, or time) for inferences to be made about the relations between them.
- 18. the quality, condition, or fact of being exact and accurate.
- 20. a statement of fact, deduced from observation, to the effect that a particular natural or scientific phenomenon always occurs if certain conditions are present.
- 21. method- a method of procedure that has characterized natural science since the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses.
- 22. thinking-the objective analysis and evaluation of an issue in order to form a judgment.
- 23. the amount of space that a substance or object occupies, or that is enclosed within a container, especially when great.
Down
- 1. a coherent, typically large body of matter with no definite shape.
- 2. a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.
- 4. variable- a variable (often denoted by x ) whose variation does not depend on that of another.
- 5. an individual thing regarded as single and complete but which can also form an individual component of a larger or more complex whole.
- 6. a conceptual structure or entity on which something draws or depends.
- 9. a scientific procedure undertaken to make a discovery, test a hypothesis, or demonstrate a known fact.
- 10. the branch of science that deals with the identification of the substances of which matter is composed; the investigation of their properties and the ways in which they interact, combine, and change; and the use of these processes to form new substances.
- 11. a supposition or a system of ideas intended to explain something, especially one based on general principles independent of the thing to be explained.
- 12. figures- each of the digits of a number that are used to express it to the required degree of accuracy, starting from the first nonzero digit.
- 17. 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.
- 19. the quality or state of being correct or precise.
