  2. What are the components of good scientific observing?
    Measurements, Changes, Questions and Communication
  3. 2nd procsses of science..... ________ is another main process used in doing science. It is often important to quantify observations by suing a standard unit of measurement.
  4. 3rd process of science....... _______is an important way to organize information in science.
  5. Two special ways of classifying that can be introduced in elementary science.
    Binary classificaiton system and Multisage classification system
  6. A set of objects is divided into two groups on the basis of whether each object has a particular property.
    Binary classificaiton System
  7. The objects in the original set are sorted again and again so that a heerachy of sets and subsets is formed. (Based on differences and similarity)
    Multistage classification system
  8. 4th process of science....... _______ is an imterpretation of observations that is based on prior knowledge and experiences. (Based on experiences not observation)
  9. 5th process of science...... A _________ is a forecast of a possible outcome based on knowlege of patterns in data.
  10. 6th process of science..... Sometimes scientists or students can conrol circumstances deliberately and precisely in an experiment to obtain evidence.
  11. _______ experiemnts involve (1) deliberately changing one variable at a time, (2) observing the effect on another variable, while (3) holding all other variables constant.
  12. Three types of variables in scientific investigations....
    Manipulated Variable, Responding Vaiable, and Control variable
  13. A ______ variable (also called an independent variable) is a variable that the experimenter deliberately changes or manipulates in an investigation.
  14. A __________ variable (also called a dependent variable) is a variable that changes in an investigation in response to changes in the manipulated variable.
  15. ________ variables are variables that are deliberately kept constant or unchanged in an investigation in order not to confound the results, that is so the investigations is a "fair test".
  16. 7th process of science.... a ________ is a statement about a possible relationship that might be identified through investigations. This is one of the core activites of scientific investigations.
  17. 8th process of science..... Logically link evidence and scientific knowledge to make sense of puzzling events. (figuring out what information means)
