Do you have a school garden, packed
lunches, and pets at your school? Recycle the plant waste this
way.

Straw or dried plants (carbon)
|
 |
Manure, weeds, kitchen scraps (nitrogen)
and
|
 |
Soil or old compost
|
Key
|
Find a square metre of ground for your
heap.
|
|
Build your heap as shown in the
diagram.
|
|
Lightly water each layer.
|
|
Use the key above to colour the layers in
the heap from the bottom.
|
 |
Keep repeating layers 2, 3 and
4.
|
 |
Cut waste up small, it will rot more
quickly.
|
 |
Keep the heap moist, but not
soggy.
|
 |
Find a safe way to record temperatures in
the heap.
|
 |
See how the temperature changes over the
weeks.
|
Make a notice to encourage local families
to compost their waste plant material.
 |
Think of a way your local council could
do this on a larger scale and turn it into a
moneymaker.
|
 |
Write a letter to them explaining your
idea. List the main points for the letter in your
workbook.
