Students step into the shoes of a taxonomist. Students make observations and inferences of specimens from the six kingdoms of living things. They use a dichotomous key to key out these organisms and compare and contrast the specimens in terms of cellular organization, method for obtaining oxygen, method for excreting wastes, method for obtaining food, etc. Fledgling taxonomists learn about one species in depth, and create an illustration of this organism’s classification. Finally, they create a dichotomous key for arthropods as a culminating activity.
S7L1. Students will investigate the diversity of living organisms and how they can be compared scientifically.
a. Demonstrate the process for the development of a dichotomous key.
b. Classify organisms based on physical characteristics using a dichotomous key of the six kingdom system (archaebacteria, eubacteria, protists, fungi, plants and animals).
S7L3. Students will recognize how biological traits are passed to successive generations.
b. Compare and contrast that organisms reproduce asexually and sexually (bacteria, protists, fungi, plants & animals).
