Mitosis and Meiosis

This activity (lab) is designed to help students to learn the critical distinctions between what happens to chromosomes during mitosis vs meiosis. Students manipulate pipe-cleaner chromosomes on a template showing stages of mitosis with one pair of chromosomes until approved by the teacher. Then they repeat the exercise for meiosis until approved. After each phase, students draw in chromosomes on a summary sheet, then help other students. An application phase asks students to show the same thing using two pairs of chromosomes. Students who think they understand the critical distinctions and essential functions of these two processes going in, usually discover that it's not quite what they thought, and come out of this with a sharper understanding. This is best used as a Formative Assessment tool.

Teaching Idea

Mitosis and Meiosis Card Sort:

This minds-on activity is designed to help students review the processes of mitosis and meiosis and to ensure that students understand how chromosomes move during mitosis vs. meiosis. Students arrange the cards from a shuffled deck of the stages of mitosis and meiosis in the sequence of steps that occur during cell division by mitosis and another sequence of steps that occur during cell division by meiosis.
