A label tells us which part of a plant we are looking at. A function explains what that part does. Mixing the two can make a neat diagram less informative than it first appears.
For families exploring schools in Hougang, plant diagrams offer a practical connection between observation, representation and scientific explanation. Holy Innocents’ Primary provides a verified local school example.
This guide suggests a separate family drawing task. It is not an official school worksheet, and a diagram does not require pulling up a plant or collecting unfamiliar specimens.

CHAPTER 1 OF 4
1. Read the local Science approach
Holy Innocents’ Primary’s Science page describes inquiry-based learning, visible thinking and scientific reasoning. It also describes farming and hydroponics experiences connected with plant systems.
Its contact page lists 5 Lorong Low Koon and identifies Hougang as the nearest MRT station.
The independent task below is not one of the school’s published lessons. Use current teacher guidance and appropriate reference material when checking the parts and functions being studied.

2. Choose the kind of diagram you are making
Begin with a simple schematic drawing of a flowering plant. Include a stem, leaves, a flower and roots below a clearly marked soil line.
State that the drawing is a simplified model. It is not a photograph, a scale drawing or a claim that every plant has exactly this shape.
If drawing an intact plant you can observe, show what is visible. Do not pretend you have directly observed roots hidden inside its pot; use a checked schematic reference for those parts instead.
A simple diagram can leave out distracting surface detail while preserving the relationships needed for the explanation. Clear structure matters more than decorative shading.

3. Make each label point to the intended part
Write the names roots, stem, leaf and flower outside the outline. Draw a clear label line from each name to the relevant part.
Check the endpoint carefully. A line meant for the stem should not accidentally finish on a leaf. Avoid crossing several lines where the drawing allows a clearer arrangement.
A label line identifies a part; it does not automatically show the direction of water movement or any other process. Use arrows for a process only when their meaning is explicitly explained.
Ask another person to identify each labelled part without extra verbal hints. If they hesitate, revise the line or its endpoint rather than adding more decorative detail.
CHAPTER 4 OF 4
4. Write the function as a separate explanation
Beside the diagram, write one checked function statement for each part being studied. For a typical flowering plant, roots absorb water and mineral nutrients; the stem supports parts of the plant and transports substances.
Green leaves typically make food through photosynthesis using light energy. The word food here is not a synonym for mineral nutrients absorbed by the roots.
Keep the scope sensible: plants vary, and some parts have additional or specialised functions. A basic schematic is a starting model, not a complete account of plant diversity.
Finish by asking two different questions: “Which part is this?” and “What does it do?” A clear label and an accurate function answer different questions, and a useful Science explanation keeps that distinction visible.
