1 Question and answers rated A+ (6 pgs)
observation, question, hypothesis, prediction, experiment, analyze, conclusion
- correct answer ✔list the steps of the scientific method.
independent variable - correct answer ✔in an experiment: the factor that is
changed by the experimenter and is not affected by any other factor.
dependent variable - correct answer ✔in an experiment: the factor that
changes value as another factor is changed by the experimenter.
experimental group - correct answer ✔in an experiment: a group of samples,
etc. that receives the experimental treatment or factor
positive control - correct answer ✔in an experiment: a control group that is
treated in the same manner as the experimental group and and is designed to
give a positive result
negative control - correct answer ✔in an experiment: a control group that is
treated in the same manner as the experimental group and and is designed to
give a negative result
control group - correct answer ✔in an experiment: a group of samples, etc.
that is treated in the same way as the experimental group, but does not
receive the experimental treatment or factor. this group shows the background
level or response and is used for comparison to the experimental group.
