- 2. a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.
- 4. -It's called “manipulated” because it's the one you can change. In other words, you can decide ahead of time to increase it or decrease it.
- 6. the study of living organisms, divided into many specialized fields that cover their morphology, physiology, anatomy, behavior, origin, and distribution.
- 8. the branch of science which deals with celestial objects, space, and the physical universe as a whole
- 11. A controlled experiment is a scientific test that is directly manipulated by a scientist, in order to test a single variable at a time. The variable being tested is the independent variable, and is adjusted to see the effects on the system being studied.
- 13. -A responding variable is a variable that the researcher predicts will change if the manipulated variable changes.
- 20. 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.
- 21. Mass is both a property of a physical body and a measure of its resistance to acceleration when a net force is applied.
- 22. Scientific notation is a way of expressing numbers that are too large or too small to be conveniently written in decimal form.
- 25. the sciences concerned with the study of inanimate natural objects,
Down
- 1. advancement in devices
- 3. Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance or shape occupies or contains.
- 5. the measurement or extent of something from end to end; the greater of two or the greatest of three dimensions of a body.
- 7. Scientific laws or laws of science are statements, based on repeated experiments or observations, that describe or predict a range of natural phenomena.
- 9. the branch of science that deals with the identification of the substances of which matter is composed
- 10. The significant figures of a number written in positional notation are digits that carry meaningful contributions to its measurement resolution
- 12. -the act of noticing something or a judgment or inference from something seen or experienced
- 14. In a set of measurements, accuracy is closeness of the measurements to a specific value, while precision is the closeness of the measurements to each other.
- 15. In pattern recognition, information retrieval and classification, precision is the fraction of relevant instances among the retrieved instances, while recall is the fraction of relevant instances that were retrieved.
- 16. A scientific theory is an explanation of an aspect of the natural world that can be repeatedly tested and verified in accordance with the scientific method, using accepted protocols of observation, measurement, and evaluation of results. Where possible, theories are tested under controlled conditions in an experiment.
- 17. the branch of science concerned with the nature and properties of matter and energy
- 18. the science that deals with the earth's physical structure and substance, its history, and the processes that act on it.
- 19. study of nature
- 23. A model is an object that is used to depict another object or a system. It can be used to familiarize ourselves with non familiar objects.
- 24. the degree of compactness of a substance.
