Product Description
This bundle includes two meiosis activities and a meiosis/mitosis pre-assessment worksheet.

Independent Assortment Activity
This activity has students randomly place chromosomes during metaphase I of meiosis. Students manipulate maternal and paternal chromosomes based on the roll of a die or flip of a coin (both versions included). This activity only uses 10 pairs of chromosomes (rather than the 23 that humans have) but even with less than half, there will be a huge amount of variety in the way different groups randomly lay out their chromosomes. This can lead into a discussion of how many different combinations there would be with 23 pairs (8 million plus!).

Crossing Over Activity
This activity looks at the important process of crossing over during prophase I of meiosis. Students manipulate pieces of licorice to see how crossing over introduces variety among the chromosomes. Students will perform crossing over twice with the same chromosomes to see how even among the same set of chromosomes the location of the cross over introduces even more variation. Students will sketch their chromosomes and answer questions as they do they activity

Mitosis vs Meiosis Pre-assessment Worksheet
This worksheet is designed to be used at the beginning of a unit on mitosis and/or meiosis. The worksheet has examples of student responses to what they think about mitosis and meiosis. Students must then choose who they most agree with or write their own ideas. The worksheet was originally designed for use in a 10th grade biology class, but can easily be used in middle school.
