Project brief
COMPOST BIN
The problem
The plants in the garden at school are starting to
die. They need to be given more nutrients to help
them grow and blossom but the school gardener
can’t afford to keep buying fertiliser.
How can the school gardener use food scraps and
recyclable materials to provide nutrients to the
garden for free?
The task
Design and create a miniature compost bin using food and garden waste,
paper and cardboard. Use a calendar to record when food and garden
waste will be added to the bin and when the compost will be mixed.
Record a video explaining to the school gardener
how compost bins turn food and recyclable
materials into nutrient-rich compost for the
garden and how he/she will need to look after
the compost bin.
Important things you need to do!
• You must work in groups of 2–3 students.
• You must use a 2-L plastic ice cream container with a lid and holes in
the bottom and sides of the container so extra water can drain out
and air and micro-organisms can get in.
• The compost bin must include half of the mixture as garden waste,
one quarter of the mixture as recycled paper or cardboard and one
quarter of the mixture as food scraps.
• You must use a calendar to record when food and garden waste will
be added to the bin and when the compost will be mixed.
• The video must include an explanation of how a compost bin works
and how the gardener will need to look after it.
