This zip file contains many different activities (66 pages of student handouts and 2 PowerPoint files with a total of 146 slides) which can be used to compose a unit for AP Biology or advanced Biology students involving the major topics of Cell Structure and Function and Cell Communication. Topics in this unit include cell surface area and volume considerations and calculations, introduction to the properties of the cell membrane, compartmentalization, cell organelle structure and function. as well as many aspects of cell communication. More specifics concerning the topics addressed in this package of activities appear in the objectives at the end of this description.
While these lessons were originally designed for my AP Biology curriculum, they can be adapted to any advanced level Biology program.
This lesson packet contains a listing of the learning goals, common core learning standards, NGSS learning standards and the AP Biology performance indicators addressed in these materials. These are included in the packet and at the end of the description of this lesson.
