Floating Garden Challenge

A STEM Challenge that addresses how food can be grown on land that is flooded in Bangladesh

Years: 2, 3, 4, 5, 6, 7, 8, 9

Duration: 120mins

Curriculum Objectives: 6

Subject: Science

Resource Overview

The problem: as a result of climate change there is more rain in Bangladesh than ever before.  Land where farmers used to grow their crops is now flooded on a regular basis.  The result is families go hungry.

The challenge: to design and build a model structure that will enable farmers to grow crops even in an area that may become flooded.

Curriculum Objectives

  • Year 2 (aged 6-7)
    • Identify and compare the suitability of a variety of everyday materials, including wood, metal, plastic, glass, brick, rock, paper and cardboard for particular uses
    • Identify that most living things live in habitats to which they are suited and describe how different habitats provide for the basic needs of different kinds if animals and plants, and how they depend on each other
  • Year 3 (Age 7-8)
    • Explore the requirements of plants for life and growth (air, light, water, nutrients from soil, and room to grow) and how they vary from plant to plant.
  • Year 5 (Age 9-10)
    • Give reasons, based on evidence from comparative and fair tests, for the particular uses of everyday materials, including metals, wood and plastic.
  • Year 6 (Age 10-11)
    • Identify how animals and plants are adapted to suit their environment in different ways and that adaptation may lead to evolution.
    • Recognise that living things have changed over time and that fossils provide information about living things that inhabited the Earth millions of years ago.
