This is an amazing lab in which students study the characteristics of different types of pasta and create their own taxonomical key.
Objective: The purpose of this lab is to better understand how living organisms are classified.
Instructions: You are to construct an identification key and a dichotomous key for “The Kingdom of Pasta.” Read the background information then follow the procedures that follow.
Classification is the process of grouping objects or information based on similarities. The system of biological classification was invented by Carolus Linnaeus. This system, called binomial nomenclature, is based on evolutionary relationships between different species. All species are divided into several taxonomic categories. In order from most general to most specific, the categories are Kingdom, Phylum, Class, Order, Family, Genus, & Species. A species’ name is base biological name consists of the genus (capitalized) followed by the species (lowercase) and are types in italics. (EXAMPLES: Humans are Homo sapiens and Lynx are Lynx rufus.) Biological names are in Latin because Latin is a dead language and does not undergo changes like other languages.
A dichotomous key is a series of paired questions that refer to structural features. The answer to each question leads the reader to a different pair of questions each time until a definite classification can be made. The questions are designed to continually separate the subjects based on their structural differences.
