Spending Time in Mitosis

This lab is my own adaptation of a lab I used years ago, with some updates in procedure.

Some teachers like to have students count cells on microscope slides. Others find that this is very difficult, so they use printed images. In this version, you can use either, or both, OR have students use images available on the internet. 

This posting includes the lab packet, and two files you can download to use as pictures for use on a computer or to print. Please note that in my lab instructions, students are not told how to calculate the minutes in each phase or the number of wedges to fill in on the graph. This is deliberate, and requires students to some problem solving! You may need to help you class through this process, but I encourage you to make them think!
