Bees and pollination

Bees and pollination: how flowers and insects depend on each other. Bees visit flowers for nectar, pollen sticks to their bodies and transfers to the next flower. Without pollination many plants cannot make seeds or fruit. Why bees matter for the food we eat.

Quick check

If the learner saw a bee buzzing around flowers in the garden, could they explain how the bee is helping the plant — and why that matters for the food we eat?

Ask this to see whether the topic is secure.

Topic // Mastery

What mastery looks like

What a learner can do once this topic is secure.
  • Describe how pollen moves from one flower to another when a bee visits to collect nectar
  • Explain that many fruits and vegetables depend on bees or other insects for pollination
  • State what would happen to a garden or farm if there were no pollinating insects

Teaching notes

From the Marble Skill Taxonomy. These notes have not been validated in classrooms, so treat them as a starting point for your own judgement.

The approach

For ages 7-9, teach bees and pollination as two linked ideas: the MECHANISM (a bee visits a flower for nectar, pollen sticks to its fuzzy body and rubs off onto the next flower) and the INTERDEPENDENCE (the bee gets food, the plant gets pollinated and can then make seeds and fruit; many of our foods depend on this). The crux children miss is the invisible pollen transfer BETWEEN flowers, so make it visible, distinguish pollination from the later seed/fruit stages, and anchor it to familiar foods like apples and strawberries.

Common misconceptions

  • 'Bees make/collect pollen on purpose to pollinate' — pollination is largely an accidental by-product of nectar-seeking.
  • 'Pollen is the same as nectar / a seed' — they are different things with different roles.
  • 'Pollination happens within one flower only' — the key idea is transfer BETWEEN flowers.
  • 'Only bees pollinate' — butterflies, hoverflies, beetles and others pollinate too.
  • 'Bees make honey and that's pollination' — conflating honey production with pollination.

Useful representations

  • A bee-and-flower scene with visible pollen grains transferring between flowers.
  • A labelled flower (nectar, pollen, stigma) with each part's role.
  • A before/after 'with bees vs no bees' fruit-set comparison.
  • A pollinator-to-crop matching set linking to our food.

Teaching practices

  • Make the invisible pollen transfer VISIBLE (grains sticking to the bee, rubbing onto the next flower) — it's the crux children miss.
  • Teach both the mechanism AND the mutual dependence (bee gets food, plant gets pollinated), not just one.
  • Anchor it to children's own food (apples, strawberries, tomatoes) so 'why pollinators matter' is concrete.
  • Distinguish pollination (pollen moving between flowers) from seed formation and dispersal that follow.
  • Use a no-pollinator contrast to make the consequence and interdependence vivid.

Activities to try

  1. 1

    Be the bee: carry the pollen flower to flower

    Why it works: For many plants, pollination happens when pollen accidentally rides from one flower to another on a food-seeking bee; this transfer is what lets the plant make seeds and fruit, so the bee and the flower (and we) depend on each other.

    1. Move a bee from one flower to a second flower: at the first flower it drinks nectar and pollen grains cling to its fuzzy body; at the second flower some of that pollen rubs off onto the flower's centre (stigma).
    2. Watch what happens next — the pollinated flower swells and ripens into a fruit (e.g. an apple or strawberry); in this model, flowers that were never visited make no fruit (in real life, unvisited flowers of these plants make little, small or misshapen fruit).
    3. Zoom in to look closely at the pollen grains on the bee's hairs and at the stigma where they land.
    4. Try a 'no pollinators' version: with no bee visiting, the flowers stay unvisited, and in this model none turn to fruit (real plants would make far less fruit); picture a shop shelf with far fewer apples and strawberries. Compare this with the version where bees did visit.
    5. Say in your own words what the bee does for the flower, what the flower does for the bee, and why this matters for the food we eat.
  2. 2

    Hands-on pollen transfer with a flour-dusted 'bee'

    Why it works: Pollen transfer is accidental — it sticks to and rubs off a fuzzy visitor — and it is a separate, earlier step from seed formation and fruit growth.

    1. Sprinkle flour (standing for pollen) on the centre of a first paper 'flower', then let a pipe-cleaner or cotton-wool 'bee' visit it so flour clings to the fuzzy 'bee'.
    2. Touch the 'bee' to a second paper 'flower' and look at the flour (pollen) left behind.
    3. Describe how the pollen got from the first flower to the second without the bee meaning to pollinate the flower.
    4. Discuss which part of this is pollination (the pollen moving between flowers), and what comes after it (seeds, then fruit).
  3. 3

    Label the flower and explain why it matters

    Why it works: Knowing the named parts (nectar as the bee's food, pollen as what transfers, stigma as where it lands) supports telling the full pollination-to-food story.

    1. On a labelled flower-and-bee scene, identify nectar, pollen and stigma and say what each does.
    2. Reveal a 'why it matters' note linking the flower to foods we eat (apples, strawberries, tomatoes).
    3. In your own words, connect each part to its role in the pollination story.
