Sustainable Kiwi Invention Design

Read the short design brief, then plan and pitch an invention that could help a place in Aotearoa New Zealand. Use clear, persuasive language and explain how your design is sustainable. You may invent a solution, but keep your claims realistic.

Design brief: A cleaner awa

After heavy rain, litter washes from streets into a local awa (river). The litter can harm manu (birds) and other wildlife. A community group wants an invention that helps stop litter reaching the water without blocking fish or making flooding worse. It should use durable materials, need little energy and be easy for people to maintain. Your task is to create a sustainable invention and persuade the group to try it.

Understand and choose

Use the brief to complete each task. Your answers should show how language can explain a problem and make an idea convincing.

1.Which sentence states the main problem the invention needs to address?

Litter can wash from streets into an awa and harm wildlife.
All rivers need to be made deeper.
Birds should be kept away from rivers.

2.The brief says the invention must not block fish or make flooding worse. Name one design feature that could help meet both needs.

3.Match each kupu to its English meaning.

awa
manu
ponga
kauri

bird
kauri tree
tree fern
river

4.Which material choice is most clearly sustainable for a reusable litter-catching device?

A durable recycled-plastic mesh, repaired when needed
Single-use plastic bags replaced every day
A fragile material that must be discarded after rain

5.Rewrite this plain statement as a persuasive but realistic slogan for the invention: “It catches litter near the river.”

Invent and pitch

Develop an idea for the design brief. Include practical details and use language that helps a community group understand why it is worth testing.

6.Give your invention a name and describe what it does in one clear sentence.

7.Choose two useful features for your invention and explain briefly how each one helps it meet the design brief.

8.Plan a labelled sketch of your invention. Show the litter, the direction of water flow and two important parts. Use the drawing space to make the design understandable.

Draw and label your design here. Include an arrow for the direction of water flow.

9.Write a short pitch to the community group. Explain the problem, how your invention works, one environmental benefit and one way local people could help maintain it. Use at least one persuasive word or phrase.

10.Review your pitch. Underline the phrase that gives a reason to act, then name one detail that makes your proposal realistic rather than an unsupported promise.
