Brief DescriptionStudents learn why plants have both common and scientific names, then complete the activity by matching each common plant name with its scientific name. Work sheet included.

Lesson PlanIn this activity, students use online or library resources to learn more about some common plants. They match the common names of those plants with their scientific names on the Education World Pair the Plant Names work sheet.
Start the lesson by explaining to students that most plants have both common names and scientific names. That might be confusing to students, but you can explain that the system of giving scientific names to plants resulted from the fact that scientists were confused too! They were confused because so many plants (and animals) had different names; people in different places, or people who spoke different languages, referred to the same plants and animals by different common names. In 1758, Carl Linnaeus, a Swedish biologist, proposed a universal system for naming all living things. That system provides two names for a species -- a family name (generic name or genus name), which always has a capital letter as the first letter, and a personal name (specific name), which is always in lower case letters.
Help make this point with students by comparing scientific family names to their own family names. Point out that each member of a family has a last name (surname) that identifies the family and a first name (specific or personal name) that identifies that individual member of the family.
After sharing that information, introduce students to the Noble Foundation Plant Image Gallery. Students can use this image gallery to search for plants by their common or scientific names. You might use this resource to show students that two different species of goldenrod have the same last name and different first names. Do this by clicking on the Forbs (plants other than grasses) link on the home page, then on Common Names. Click on the common name Tall goldenrod, which is identified by its scientific name Solidago gigantean. Then click on the common name Flat-topped goldenrod, which carries the scientific name Solidago nitida. Another example: The Spach evening primrose is known scientifically as Oenothera spachiana, and the four-point evening primrose is known as Oenothera rhombipetala. Note: This does not work for all common names.
Hand out the Pair the Plant Names! work sheet. Students can use plant encyclopedias, field guides, and other library resources to complete the activity. If students are able to use online resources, the Noble Foundation Plant Image Gallery site is an excellent resource -- and a great source of plant photographs too! Another good source is the Plants Database.
