Cell division. Mitosis Simulation Playbook

Menu
Before Starting the Simulation:
  • Ensure all VR headsets are charged and properly calibrated
  • Review safety guidelines for VR equipment use
  • Show students the essential VR gestures and controls
  • Plan your time: allocate 20 minutes for interaction and 10–15 minutes for reflection
During the Simulation:
  • Designate student helpers to assist their peers
  • Circulate throughout the classroom to support struggling students
  • Guide students to observe and document cellular changes
  • Prompt students to share their observations verbally
Group Organization:
  • For classes with limited devices, form triads: one in VR, two observing/discussing
  • Rotate roles every 5–7 minutes
  • Provide printed diagrams of cellular structures for note-taking during observation
Troubleshooting Technical Issues:
  • Preload simulation and test each headset prior to class
  • Keep a backup tablet with 2D version of the lab in case of headset malfunction
  • Maintain clear VR boundaries and warn students about physical obstacles
Recommendations for Teachers

Before simulation:

  • Quick diagram task: “Draw the 4 main phases of mitosis”
  • Ask: “Why is it important for cells to divide perfectly?”

During simulation:

  • Pause after each phase and ask: “What changed here?” and “What might go wrong?”
  • Assign roles: one group tracks spindle, another tracks chromosomes

After simulation:

  • Group task: build mitosis storyboards
  • Comparison chart: Mitosis vs Meiosis
  • Short writing: “What if mitosis didn’t exist?”
1. Simulation Overview

Simulation title: Mitosis VR Simulation

Description: The student enters a cell undergoing division and helps initiate, observe, and restore key processes of mitosis, from prophase to cytokinesis.

Simulation type: VR

Subject and age: Biology, Grades 7–9

Key topics:

  • Phases of mitosis
  • Chromosome behavior
  • Role of spindle apparatus and centrioles
  • Cell cycle regulation
2. Key Simulation Milestones
Time Simulation stage What happens before the action? What should be done? What happens after the action?
00:00 Initial overview The student sees an animal cell with only the nucleus and centrosomes present. Nothing needs to be done at this stage. The student may use the wrist tablet for additional information. The simulation begins.
00:12 Interphase A nucleus contains six decondensed DNA strands. An orange centrosome consisting of two centrioles is visible. 1. Click each DNA molecule to duplicate it.
2. Click each centrosome to duplicate it. 		1. All DNA molecules become duplicated.
2. The centrosome also duplicates.
00:46 Prophase The nucleus is intact; chromatin is loose. 1. Click each chromatin strand to condense it.
2. Hold the trigger on each centrosome and drag it to opposite poles.
3. Click the nuclear envelope three times to break it down.
4. Click each centrosome to attach microtubules to the chromosomes. 		1. Chromatin condenses into chromosomes.
2. Centrosomes move to opposite poles.
3. The nuclear envelope disappears.
4. Microtubules attach to chromosomes.
02:15 Metaphase Chromosomes float randomly within the cell. Click each chromosome to align it along the equatorial plane. Chromosomes align at the metaphase plate.
03:00 Anaphase Sister chromatids remain attached. 1. Click each chromosome to separate sister chromatids.
2. Click each centrosome to pull chromatids toward opposite poles. 		1. Sister chromatids separate.
2. Daughter chromatids move toward opposite cell poles.
04:09 Telophase Chromatids have reached opposite ends of the cell. 1. Click each chromatid to decondense it.
2. Click near the chromosomes to rebuild the nuclear envelope.
3. Click each centrosome to disassemble microtubules. 		1. Chromosomes decondense.
2. Two new nuclear envelopes form.
3. Microtubules are dismantled.
04:51 Cytokinesis One cell is present; no division furrow is visible. Grab the model with both hands and pull it apart to form two cells. Two identical daughter cells are formed.
3. Theoretical Anchors (from the scene)
  • Cell cycle — the continuous sequence of growth and division that cells undergo, consisting of interphase (G₁, S, G₂) and the mitotic phase (M). It ensures proper replication and distribution of genetic material.
  • Interphase — the preparatory stage before mitosis during which the cell grows (G₁), replicates its DNA (S), and produces necessary proteins and organelles (G₂). DNA remains in the form of uncoiled chromatin.
  • DNA replication — the S-phase process in which the entire genome is duplicated so each daughter cell receives an identical set of genetic information.
  • Mitosis (M phase) — a highly ordered form of nuclear division that produces two genetically identical daughter cells. It includes five stages: prophase, metaphase, anaphase, telophase, and cytokinesis.
  • Prophase — chromatin condenses into chromosomes, spindle fibers begin forming from centrioles, and the nuclear envelope breaks down, allowing spindle attachment.
  • Metaphase — chromosomes line up along the metaphase plate (cell equator), and spindle fibers from opposite poles attach to kinetochores.
  • Anaphase — sister chromatids separate and are pulled toward opposite poles as spindle fibers shorten, ensuring equal chromosome distribution.
  • Telophase — new nuclear envelopes form around each chromosome set, chromosomes decondense, and nucleoli reappear.
  • Cytokinesis — the cytoplasm divides into two daughter cells. In animal cells this occurs via a cleavage furrow, while plant cells form a cell plate.
  • Spindle fibers and centrioles — microtubule-based structures that coordinate chromosome movement. Centrioles organize the spindle, while spindle fibers attach to and pull chromatids to opposite poles.
  • Cell cycle checkpoints — regulatory points (G₁/S, G₂/M, spindle checkpoint) that verify DNA integrity, chromosomal alignment, and proper cell size before division proceeds.
  • Biological significance of mitosis — ensures genetic stability by producing identical cells needed for growth, tissue repair, and asexual reproduction. Errors in mitosis can lead to chromosomal abnormalities or uncontrolled cell division (cancer).
  • Comparison with meiosis — unlike mitosis, which produces two identical diploid cells, meiosis generates four genetically unique haploid cells required for sexual reproduction.
4. Reflection Questions
  • What would happen if the chromosomes didn’t line up correctly in metaphase?
  • How did you feel watching the cell “split itself”?
  • Why is mitosis important beyond just creating new cells?
  • Which phase seemed most complex to restore? Why?
  • How do you think mitosis differs in plant cells?
5. Hard Skill Questions
  • List and describe the phases of mitosis in order.
  • What is the function of spindle fibers during mitosis?
  • How does cytokinesis differ from telophase?
  • What ensures that each daughter cell gets identical DNA?
  • Why is mitosis essential for growth and repair?
