Question and answer
enumerate and define different science processes
1. Observation This is the most fundamental of all of the processes. Observation may be defined as the gathering of information through the use of any one, or combination of the five basic senses; sight, hearing, touch, taste, and smell. 2. [ Measurement Measurement is an observation made more specific by comparing some attribute of a system to a standard of reference. An example is when the
length of an object is expressed in terms of the length of a meter or when the mass of an object is expressed by referring to a standard such as a gram. Measurement and observation are the only process skills that are actually two forms of the same thing. 3. Classification Classification is the process of grouping objects on the basis of observable traits. Objects that share a given characteristic can be said to belong to the same set. The process is somewhat arbitrary depending upon the identifying trait selected. 4. Quantification Quantification refers to the process of using numbers to express observations rather than relying only on qualitative descriptions. 5. Inferring Inferring is an inventive process in which an assumption of cause is generated to explain an observed event. This is a very common function and is influenced by culture and personal theories of nature. 6. Predicting This process deals with projecting events based upon a body of information. One might project in a future tense, a sort of trend analysis, or one might look for an historical precedent to a current circumstance. 7. Relationships The process skill of relationships deals with the interaction of variables. This interaction can be thought of as a kind of influence--counter influence occurring among a system's variables. 8. Communication This process actually refers to a group of skills, all of which represent some form of systematic reporting of data. 10. Controlling variables This process is also a kind of group process because one may engage in several different behaviors in an attempt to control variables. 11. Operational definitions An operational definition is one that is made in measurable, or observable terms. 12. ]
