There are some things that need to be considered before items are classified. Below are some general rules to remember when classifying either living things or other items. Remember that in science it is possible that the methods of classification can be changed whenever new scientific knowledge becomes available.

  • Know what items are being classified.
  • Make many observations about the things to be classified.
  • Classify the things based on the observations.
  • Try to group the most similar things together.
  • When grouping living things, place the most similar organisms in the same species.
  • The largest, or most general, group of living things is the kingdom.
