Plastic Bottle Greenhouse
The holes have been dug, posts have been cemented in place and two plastic bottle frames have been put up.
WE NEED MORE 2LT PLASTIC BOTTLES

Leaves
The out door structure club built a leaf mould bin to make compost. We were interested to see what happened to the leaves, as they started to decay.
We collected leaves and grass, some that had already fallen from the trees and others that were still attached. We laminated our collections and took a photo copy so that we could compare the two.
A creative way to watch the process of turning leaves into compost.

Leaf Mould Bin
The out door structure club built a leaf mould bin to make compost.
Autumn leaves are mainly broken down by the slow action of fungi rather than by bacteria that decompose other compost bin ingredients quickly, so it’s best to compost them separately in a simple cage.
The leaves of all deciduous trees make good leaf mould. Small thin leaves such as birch break down fairly quickly, while large leathery ones such as chestnut are better being shredded first. Evergreen leaves and conifer needles take far longer to rot and should not be included in great quantities, and then only when chopped.
After a year, the leaves will have only half rotted, but will break up easily. They can be used for soil improvement or for mulching around shrubs, where they will continue to rot down in situ. After two years most will have turned into fine, dark leaf mould. Which can be used as a seed-sowing medium or mixed with equal parts of fine garden compost, loam and sharp sand for potting.
Stacking Bottles
Once we had washed and taken the labels off the bottles, it was time to cut the bottoms off and start to stack them onto canes. We stacked the bottles one inside another with a garden cane supporting them through the middle. The last bottle had to be reversed so it faced the opposite way to the others enabling it to fit with the cane sticking out of the tops of the bottles.
Our next job is to attach the canes and bottles to the frame of the greenhouse.
The Thermometer
We decided to make the thermometer with recycled wood left from the builders. We used chalk board paint so that it can be used for other collections in the future.
Our First Project, Plastic Bottle Greenhouse
Our first project:- to construct a plastic bottle greenhouse.
We started by cleaning and removing the labels from the 2 ltr bottles we had collected. It soon became apparent that we needed a lot more bottles to complete the greenhouse. We had a team discussion and came up with the idea of making a thermometer to enable our friends, parents and staff to see at a glance how our collection is going.
