Middle School Science Lessons

Objectives:

• Students will create models for different phases of Mitosis

Materials:

• paper plates
• pipe cleaners cut in 1/3rds or 1/4ths
• hot glue & gun
• markers
• scissors
• Reference material for the phases of Mitosis
  • Mitosis Flip Book (pdf)
  • Mitosis Notes
  • Mitosis Vocabulary – Definitions will pop up when you advance the slides (Google Slides, view only)
    • Flashcards – print and cut out (pdf)
  • Mitosis Coloring
    • Guided Activity – we did this together as a class
  • Mitosis Onion Cell – Identification Practice
    • Guided activity – Have students color code the phases identifying one phase at a time and count all the cells in that phase

Directions:

• Assign students into groups for each phase.
  • Interphase
  • Prophase
  • Metaphase
  • Anaphase
  • Telophase (1 plate cut or use 2 plates overlapping)
  • Cytokinesis (2 identical plates)
• Each student will create a version of their assigned phase, for example, Metaphase.
• Students will select 4 different colored chromosomes with copies if needed
• They will set up their cell then once checked, can hot glue pipe cleaners into position.
• Each cell should have the followed as needed: (the ones pictures are an older version)
  • nucleus/nuclear membrane
  • centrioles
  • chromatin or chromosomes/chromatids – 4 different colors
  • spindle fibers
  • one or two additional organelles
  • their phase, name, and class on the back
• When done, have one person from each group meet and make a timeline from Interphase to Cytokinesis.
• Have students walk around the room and look at the different timelines created.
