Allow students to discover the purpose and importance of cell division (mitosis) in organism growth, development, and for replacing dead and dying cells.
Students model an exponential growth pattern using pennies to represent cells and a grid containing 40 squares, each square representing one week of human gestation.
I typically use this activity with students after we have investigated the phases of mitosis and the cell cycle. I then follow up with allowing students to investigate the cell cycle in a variety of specialized cells.
