Exemplars (from the NaCCA curriculum)

- Learners can be engaged in an activity that explains cyclic movement. (The second hand of an analogue clock, merry-go-round and circular cards, musical chairs could be used).
- Relate this activity to the occurrence of day and night and explain that the appearance of the Sun, Moon and stars follow a cyclic pattern.
- Let learners suggest other events in their environment that happen over and over again in a cycle. For example, dry and wet seasons.
- Learners make sketches displaying events that take place in the day and those that take place in the night.
