SCI 101- test 1 || CORRECTLY SOLVED!!
science correct answers the systematic study of the structure and behavior of the physical and
natural world through observation and experiment
objects correct answers things that can be seen or touched
properties correct answers qualities or attributes characteristic of an object
referents correct answers comparative properties in other, more familiar objects
problem correct answers language can be subjective
3 steps of measurement correct answers 1. comparing the referent unit to the property
2. following a procedure specifying how the comparison is done
3. counting how many standard units describe the property under consideration
laws correct answers important relationship observed to occur time after time. descriptive in
nature
models correct answers description of a theory or idea that accounts for all known properties. can
be physical, mathematical, based on a sketch or an analogy.
theories correct answers broadly based set of working hypotheses, based upon considerable
experimental support, form the framework of thought and experiment
pseudoscience correct answers 1. academic and scientific background of claimant
2. history of review by scientific peers
3. participation in scientific institutions and organizations
4. claim published in peer-reviewed journal and independently validated by others
5. does the claimant have something to gain
3 combinations of length and time correct answers 1. speed- change in position with respect to
time
2. velocity- describes speed and direction
2. acceleration- rate at which motion changes over time
2 fundamental components of length and time correct answers 1. change in position
2. change in time
types of motion correct answers 1. vertical
2. horizontal
2 basic observations correct answers 1. gravity acts at all times
2. acceleration is independent of the objects motion
