Lean, Mean Information Machine: Using a Simple Model to Learn about Chromosomal DNA

Learners observe a model of a cell and its chromosomal DNA made from a plastic egg and dental floss. Use this model to illustrate how much DNA is held in one cell. For comparison, multiple eggs can be prepared representing different species and their DNA. Introduce the demonstration by talking about the actual size of cells and DNA. Activity contains extension questions to assess learners' understanding.
