  • Investigation: Mitosis

    Investigation: Mitosis

    This mitosis investigation was created during the 2020 pandemic for remote learning. In previous years, biology students would view slides in the lab and analyze data on cancer and mitotic index. This at-home activity only looks at the mitosis of onion cells and I plan to add cancer and mitotic index as a separate activity.…

  • Cell Cycle Labeling

    Cell Cycle Labeling

    Students label the image of a cell undergoing mitosis and answer questions about the cell cycle. 

  • Investigation:  Mitosis and Cancer Cells

    Investigation: Mitosis and Cancer Cells

    The first part of this investigation, students examine slides of mitosis in an onion root tip and count the number of cells in each phase of the cell cycle.  An equation is then used to estimate the percentage of time the cell spends in each phase and students  create a bar graph to display results. …

  • Mitosis Coloring

    Mitosis Coloring

    Students read about each of the phases of the cell cycle and label and color a diagram that shows details of  interphase, prophase, metaphase, anaphase, and telophase.    Students must also label cell structures like the centrioles, aster, spindle, and nuclear membrane. This worksheet can be used as reinforcement for a lesson on mitosis and…
