A group of learners simulates the spread of disease by trading slips of paper, one set of which has been treated with a baking soda solution.

Working in small groups, learners receive a written scenario regarding a bacterium with a certain goal it must carry out.

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.
