This assignment can be a stand-alone activity to help students learn to identify the phases of mitosis by viewing various animations. There are several sites to visit, such as cellsalive.com tasks to perform at each site, such as labeling and making comparisons.
The biology.arizona.edu site also asks students to identify and count the number of cells in each phase of mitosis and calculate the percentage of cells in each phase. Students can then use that information to determine what phase cells spend most of their time in.
A final tasks asks students to draw each phase of mitosis, either on the paper or use an online drawing program, like sketchtoy.com and share their work.
HS-LS1-4 Use a model to illustrate the role of cellular division (mitosis) and differentiation in producing and maintaining complex organisms.
