This lab partially aligns with the NGSS performance expectation:
HS-LS1-4 Use a model to illustrate the role of cellular division (mitosis) and differentiation in producing and maintaining complex organisms.
Science and Engineering Practice: The lab involves the use of a model (frequency of stage/relative length of stage) to predict the frequency/relative length of each stage in a different cell type.
Cross-Cutting Concept: The system is the mitosis and interphase part of the cell cycle (and the lab includes a look at how this system would be different in a different cell type).
DCI: The lab only indirectly addresses the role of mitosis in maintaining organisms. The cell cycle aspect hints at this, but largely this is a lab that could be done following students' creation of a physical model (e.g., yarn).
The word version is included so that you may edit to incorporate your own activities in the pre-lab.
