This worksheet is designed to be used at the beginning of a unit on mitosis and/or meiosis. This worksheet was created in the same format as those found in the Uncovering Student Ideas series by NSTA. 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.
