7Bs.02 Identify and describe the functions of cell structures.

7Bp.04 Use and construct dichotomous keys to classify species and groups of related organisms.




In this experiment, the student classifies various living organisms and groups them with respect to the habitats they live in, the characteristics they have and their structures. Dichotomous key is used to lead the student in identifying the organism while practicing it’s characteristics. It is emphasized that even though the physical traits that one organism has might resemble the other, they might be classified as a different class.
