B5 Science · Term 2 Week 3: Life Cycles of Organisms

Lesson notes

Learning Objectives

Indicator: B5.2.2.1.1 - Relate structure of the parts of a plant (leaves, stem, root, flower) to the functions they perform

By the end of the lesson, learners can:

Identify and name the four main parts of a flowering plant: roots, stem, leaves, and flower.
Observe and describe the visible structures of each plant part (for example, root hairs, leaf veins, stem nodes) using simple language.
Relate each plant part’s structure to the function it performs (roots anchor and absorb; stem supports and transports; leaves make food; flower helps in reproduction).
Draw, colour, and label a complete plant showing all four parts and state one function for each part.
Sort and group different young plants according to similarities and differences in their roots, stems, and leaves.

Exemplars (from the NaCCA curriculum)

- Discuss functions of parts of plants with learners.
- Learners go on a nature walk to uproot young plants from school surroundings and bring them to class.
- Learners, in groups, observe parts of the plants and relate them to the functions they perform, e.g. the thin and large surface area of leaves and the presence of green colouring matter enhance their work. The roots are for anchorage and absorption of nutrients from the soil. The stem supports the upper part of the plant; conduct water and minerals from the roots to the leaves; carry food from leaves to other parts of the plant.
- Learners draw and colour a plant and label the parts.
