Overview
In this activity, the instructor builds an alien cell out of different materials (see pdf) that resemble the organelles and compartments of a normal, plant cell. The instructor brings the alien cell to class and gets students to investigate what kind of cell it is.
The instructor dissects the alien cell while one student films what is happening up close. The video is projected onto a white board so that the whole class can see.
Students participate by sharing their cell knowledge with the class. Together, the class deduces what organelles are present in the alien cell and how they function, and compare them to the organelles of a normal plant cell.
Instructional Objectives
Students apply their knowledge of normal “terrestrial” cells to a new scenario (an alien cell), and learn to recognize cellular components based off of their location in the cell, or by their morphology or function.
Students also practice working as a team.
