  • ==independent variable-== the quantity or characteristics that a scientist directly manipulates
  • ==dependent variable-== the quantity that changes in response to the independent variable
  • ==constants-== quantities in an experiment that are kept the same
  • ==control group-== a group that is completely unaltered from normal
  • ==experimental group-== group that is altered in a specific way to observe change
