Classification & Taxonomy

Seventh graders learn how scientists classify the millions of living things — grouping them into kingdoms and ever more specific levels down to species, and naming each with the two-part scientific name system.

Learning Objectives

Students will be able to…

  • ✓Explain classification.
  • ✓Name the major kingdoms.
  • ✓Order the taxonomic levels.
  • ✓Explain scientific names.
Essential Question

Scientists have identified millions of species — with millions more undiscovered. How do they organize all of life into a system that lets anyone, anywhere, know exactly which organism you mean?

QUESTION 1
What is taxonomy?
The science of classifying and naming living things.
QUESTION 2
What is the most specific level of classification?
Species.
QUESTION 3
What is binomial nomenclature? Give an example.
The two-name (genus + species) scientific naming system — like Homo sapiens.

Elaborate: build a key.

Have students build a simple dichotomous key that uses yes/no questions to identify a set of organisms. A printable classification sheet is in the Science library.
