1. Mitosis Foldable

2. Do Now
On a whiteboard, put the following events in order based on your knowledge of cell division (mitosis)
A) Spindle fibers attach to the chromatids at the centromere; chromosomes appear at the equator of the cell
B) Two new nuclei form and chromosomes unwind into chromatin
C) Centrioles and spindle fibers appear and begin to move to the poles; chromatin condenses into chromosomes (easier to move around the cell)
D) Chromatids separate and begin to move to opposite ends of the cell (poles)

4. Foldable Step 1 Step 2 Step 3
Fold your paper in half length wise (hot dog)
Step 2
Fold your paper in half twice from top to bottom (create quarters)
Step 3
Unfold and cut each quarter through the front panel only (see Mr. Tran’s example for help)

5. Foldable Step 4 Step 5 Step 6
On each front flap, list the 4 phases of mitosis
Prophase, Metaphase, Anaphase, Telophase (PMAT)
Step 5
On the inside of each flap, list the key events/steps that occur in that phase (check notes/videos)
Ex. Prophase- Mitosis begins, centrioles and spindle fibers appear and begin to move to opposite sides of the cell, chromatin condenses into chromosomes
Step 6
On the opposite side, draw a picture of a cell in that phase (be sure to label the structures listed on the whiteboard)

Mitosis Quiz
Mitosis flip books may be edited based on today’s activity and help from Mr. Tran and turned in by Friday (before quiz)
