Insects in ecosystems

ScienceInsects & MinibeastsAges 9–11

Insects in ecosystems: the many roles insects play. Pollinators (bees, butterflies, hoverflies), decomposers (dung beetles, fly larvae), food source for birds, bats, fish, and frogs, and pest controllers (ladybirds eating aphids). The thought experiment: what would happen if all insects disappeared?

Teaching Table

Set out your lesson

Practise the bounded task in Insects in ecosystems; see exact limits before inferring broader coverage.

Activity

Understand one organism can affect another.

Policy

Exact directed source edges retained; earlier authorship is not learner attainment.

Materials

These supplied stage cards
Scrap paper and pencil; oral/pointing response where appropriate

Sequence

Read readiness and decide on support without treating prerequisite authoring as learner readiness.
Open Show first and explain its model.
Use Guided Try with support and its separate adult key.
Close Show and guided keys before Try, unless this Try is explicitly supported.
Reflect on an actual attempt, including help used.

No Printer

Use the supplied screen cards; copying the exact task to paper is optional, not required.

Privacy

Use only invented scenarios and optional anonymous local notes. Do not request names, photos, family finances, medical data, accounts or uploads. Stop uncomfortable physical activity.

Use the complete materials on screen or print only the current sheet. Keep adult guidance out of learner view. Retain an earlier model only when the current step supplies it as context.

Teaching limits and safe use

These are finite task opportunities, not proof of mastery. Record what was attempted and what support was used.

No local species survey or guaranteed extinction forecast; fictional garden web is not a population measurement.

Use only invented scenarios and optional anonymous local notes. Do not request names, photos, family finances, medical data, accounts or uploads. Stop uncomfortable physical activity.

Check understanding

Name at least three different ecological roles that insects play such as pollinator, decomposer, and food source
Explain how the removal of one insect group like bees would affect plants, other animals, and humans
Describe a specific example of insects as pest controllers such as ladybirds controlling aphid populations

“If you asked your child what would happen if all the insects in the world disappeared tomorrow, could they explain the chain of problems that would cause — for plants, animals, and people?”
