When first introduced to the words "Kingdom," "Phylum," "Class," and so on, students don't have too much background knowledge to build on... BUT, students DO understand the words, "Planet," "Continent," and "Country." Show students that taxonomy is NOT that complicated when you interchange the word "Planet" for "Kingdom" in this activity that will have every student on their feet (but not for long!) until you taxonomize the class down to one specific student! This activity is short, but can be expanded upon for an entire class period!
