Name ______________________________ Class ___________________ Date __________________ Skills Practice Lab DATASHEET FOR CHAPTER LAB Shape Island You are a biologist exploring uncharted parts of the world to look for new animal species. You sailed for days across the ocean and finally found Shape Island hundreds of miles south of Hawaii. Shape Island has some very unusual organisms. The shape of each organism is a variation of a geometric shape. You have spent more than a year collecting and classifying specimens. You have been able to assign a two-part scientific name to most of the species that you have collected. Now, you must assign a two-part scientific name to each of the last 12 specimens collected before you begin your journey home. OBJECTIVES Classify organisms. Name organisms. PROCEDURE 1. Beside each organism pictured on the next page, write a name for the organism. The first organism has already been named, but you must name the remaining 12. Use the glossary of Greek and Latin prefixes, suffixes, and root words in the table to help you name the organisms.

Analyzing Results If you gave species 1 a common name, such as round-faceno-nose, would any other scientist know which of the newly discovered organisms you were referring to? Explain. How many others have a round face and no nose? _______________________________________________________________ 2. Organizing Data Describe two characteristics that are shared by all of your newly discovered specimens. _______________________________________________________________ _______________________________________________________________ Original content Copyright © by Holt, Rinehart and Winston.

Applying Conclusions One more organism exists on Shape Island, but you have not been able to capture it. However, your supplies are running out, and you must start sailing for home. You have had a good look at the unusual animal and can draw it in detail. Draw an animal that is different from all of the others, and give it a two-part scientific name. APPLYING YOUR DATA Look up the scientific names Mertensia virginica and Porcellio scaber. Answer the following questions as they apply to each organism: Is the organism a plant or an animal? How many common names does the organism have? How many scientific names does it have? Think of the name of your favorite fruit or vegetable. Find out if it has other common names, and find out its two-part scientific name. __________________________________________________________________ __________________________________________________________________ __________________________________________________________________ __________________________________________________________________ __________________________________________________________________ __________________________________________________________________ __________________________________________________________________ __________________________________________________________________ __________________________________________________________________ Original content Copyright © by Holt, Rinehart and Winston.

Holt Science and Technology 75 Classification TEACHERS RESOURCES Skills Practice Lab DATASHEET FOR CHAPTER LAB Shape Island Teacher Notes TIME REQUIRED One 45-minute class period Maurine Marchani Raymond Park Middle School Indianapolis, Indiana RATING Teacher Prep–1 Student Set-Up–1 Concept Level–2 Clean Up–1 LAB NOTES This lab will help students demonstrate an understanding of binomial nomenclature by using a key to assign scientific names to fictional organisms. After completing the lab, students should be able to explain the function of the scientific naming system. This chapter on classification uses the term two-part scientific name instead of binomial nomenclature. You may wish to introduce the latter here. This activity may be more successful if you review prefixes, suffixes, and root words briefly before beginning. Remind students that the genus name is capitalized but the species name is not and that both words are underlined or italicized. Original content Copyright © by Holt, Rinehart and Winston.
