The students can then gather their materials and construct
their models. During this time the teacher circulates around the
class to assist students and provide prompts for further
discussion. Once constructed the students can then take
them around the class and ask others to predict the molecule by
counting the beads in each pipe cleaner “shell”. If a display is to
be made from the models, then students can also produce a
backing card (Figure 5) for their molecule with some facts
about it.
