2013 revision

The biggest change in the 2013 revision of this activity has been to incorporate the helpful suggestion from K. Harding to make the model chromosomes from hair roller curlers. This approach provides model chromosomes that are relatively easy to make, engaging for the students to use, and an appropriate size for classroom use and storage. In addition, the introductory section of the Student Handout has been clarified and streamlined, the format of the Student Handout has been improved to facilitate classroom use, and the Teacher Preparation Notes have been revised to clarify the instructions for making model chromosomes and to explain the relationship of this activity to national standards.
