Provide "acknowledged body of knowledge" related to the concept. Emphasize the most significant aspects of the concept in an organized, organic manner. Present information sequentially so students see continuity. Draw attention to important, discrete details; don't swamp students with myriad facts.

Teacher provides info on classification schemes for living things.

Objective: To provide the students with the historical basis of biological classification, giving Aristotle's simple scheme, Linnaeus' contributions of levels of organization and binomial nomenclature and Whittaker's presently recognized five kingdom scheme.

Activity: Using the blackboard, colored chalk and imitating the same type of scheming patterns that the students used for the shoe activity, the teacher shows the progression and increasing complexity of how scientists have attempted to put living things in some kind of order so that they can be studied. When doing binomial nomenclature, many examples are given with a little explanation of why Latin was chosen. When explaining the Levels of Organization (Kingdom, Phylum, Class, Order, Family, Genus, Species) an analogy is drawn using the location of the teacher, i.e., Kingdom = country, Phylum = state, Class = city, Order = street, Family = #, Genus = last name, Species = first name. The most important point is that the more of these levels two organisms share in common, the more closely related they are. Finally, Whittaker's Five Kingdom Scheme is presented.

Assessment: Quality of students' notes; their ability to correctly answer class questions involving analysis of relationship charts and identification of the key characteristics and example organisms of each of the Kingdoms.
