Lesson notes

Learning Objectives

Indicator: B4.2.1.1.1 - Demonstrate understanding of cyclic movements in the environment

By the end of the lesson, learners can:

Define a cyclic movement as a movement that repeats itself in a regular pattern.
Demonstrate a swinging pendulum using a ball hanging on a string and describe its back-and-forth motion.
Identify at least three examples of cyclic movements in their environment, such as a clock’s second hand, a merry-go-round, a swinging pendulum, and limb movements while walking.
State one thing common to all cyclic movements: they happen over and over again in a repeating pattern.
Predict what will happen to a pendulum if the string is made longer or shorter (a simple cause-and-effect observation).

Exemplars (from the NaCCA curriculum)

- Guide learners to build a pendulum (a ball hanging on a string) and let them observe the swinging motion.
- Learners observe the following movements: (1) the second hands on an analogue clock (2) merry-go-round (3) a swinging pendulum, (4) movement of their limbs during walking.
- Assist learners to come out with one thing that is common to all the movements.
Project: Life Cycle of a Maize Plant Learners investigate the life cycle of a maize plant and report on their findings.
