Exemplars (from the NaCCA curriculum)

- Guide learners are guided to breathe out or blow air onto a transparent surface, e.g. a glass or plastic bottle and share their observations.
- Explain to learners that just as humans release water vapour when they respire, so do plants when they transpire.
- Put learners into groups and give each group a young potted plant, plastic wrap bag and a rubber band to undertake the following activities:
(1) Let learners examine the surface of the leaves of the plants and mop off any water droplets on the leaves.
(2) Tie the plastic wrap bag around the plant up to the stem and leave it for an hour. (3) Observe both plant and plastic wrap surfaces. (4) Let learners report on what happens.
