Death Cycle
On Wednesday, the 2nd of May, Room 16 drove to the Botanic Gardens on a bendy bus to learn about nature’s recycling. First we had morning tea under the huge covered courtyard with really fat birds. After that, two educators took us through a cold, dark bush walk. We had to pick a green, yellow and brown or skeleton leaf and put them in a line. The educators told us about the death cycle and that leaves have mould on them. Each year the leaves are not piling over us because of the F.B.I. That stands for fungi, bacteria and invertebrates. The invertebrates go chew, chew, chew, poo, poo, poo and the fungi and bacteria go rot, rot, rot and turn the leaves into soil.
Worm Farm
Next we went and did some worm farming. Each group made a worm farm. First we got a container with a hole in the bottom. Then we put in big, flat stones, then little stones, and then mesh so the worms can’t escape. Next we put in wet newspaper because worms need to be wet to live. Then we put in the tiger worms, and then some kitchen scraps for the worms to eat. Finally we put on a blanket, then a lid with air holes. The worm wee drains out of the hole at the bottom and can be mixed with water then put on the garden to help the plants grow.
Making a compost heap
After that we learnt how to make a compost heap. There was a green bin and a brown bin. In the green bin there were green leaves, old cabbage, lettuce, banana peels and apple cores which are all a little bit wet. Grass clippings are green waste too but not too much because it’s no good for the F.B.I. to breathe. In the brown bin there were dry twigs and leaves. We went on a twig hunt for the compost heap. We put some green materials and some brown materials on the compost heap. A compost heap needs to be on the ground so worms can get in. It can get so warm that sometimes cats sleep on it. Compost heaps also need to be moist.
