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.

In this activity, learners construct a cereal chain as a model of how proteins are made in the cell.

This laboratory exercise is designed to show learners how DNA can easily be extracted from wheat germ using simple materials.

This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells using simple materials.

In this activity (on pages 22-33), learners do the kind of work genetic scientists do, sorting and comparing (images of) genetic material strands called chromosomes.
