Parts of a Flower Worksheet (Free KS2 Science Printable)

What this worksheet teaches

The worksheet introduces the flower parts that Year 3 children are usually asked to recognise: the colourful petals that attract insects, the stamens (the male parts, each with a pollen-producing anther on top), and the carpel (the female part, with a sticky stigma at the tip that catches pollen). By colouring and labelling these parts, children begin to see a flower not just as something pretty but as the part of the plant where reproduction takes place. The aim is recognition and simple description rather than detailed biology, which keeps it age-appropriate for seven to nine year olds.

How flowers fit into the plant life cycle

In the National Curriculum, parts of a flower are taught alongside the wider life cycle of flowering plants. Pollen from an anther is carried to a stigma, often by insects such as bees or by the wind. This is pollination. Once pollen reaches the stigma, the flower can begin to make seeds inside the carpel, which later swells to form a fruit. The seeds are then spread away from the parent plant through seed dispersal by wind, water or animals. Pointing out this sequence as children label the diagram helps them connect the named parts to a purpose, which makes the vocabulary far easier to remember.

Using the worksheet at home or in class

Begin by colouring the flower so children spend time noticing where each part sits: the petals around the outside, the cluster of stamens in the middle, and the single taller carpel at the centre. Encourage them to use a different colour for the anthers and the stigma, as this draws attention to the parts that do the pollinating. Then move on to the labelling task, where they match each name from the word bank to a description. Saying the words aloud and finding the matching part on the picture reinforces both spelling and understanding. If you have a real flower such as a lily or a tulip, comparing it with the drawing makes the learning far more memorable. Lily anthers are large and easy to see, but their pollen stains clothes and lilies are poisonous to cats, so handle them with care.

Common questions children ask

Children at this age often ask why flowers are so colourful, why bees visit them, or which parts turn into seeds. These are excellent questions to explore. Colour and scent attract pollinating insects; the insects accidentally move pollen from anther to stigma as they feed on nectar; and the seeds form inside the carpel after pollination. A common mix-up is to think that bees visit flowers in order to help them; bees are collecting food, and pollination happens by accident as pollen sticks to their hairy bodies. At Year 3, naming the parts and knowing what each one does is enough; the finer detail of fertilisation comes later in school.
